It's 62 mm. So I have a 46 - 62 mm step-up ring.
That is strange, because it is said to work directly with one macro lens with a 52mm filter thread, and to require the included 62mm adapter to work with two macro lenses with 62mm filter threads.

I just checked again.

The ES-2 is 52 mm. The set includes a step-down ring for 62 > 52. For some reason, I am using two rings: a 46 > 62, then 62 > 52. A single 46 > 52 would have made more sense.

In short, if your lens' filter threads are 52 or 62 mm, you're fine without any further stepping rings. If they're other than 52 or 62, you'll need to step up or down.

It's disappointing, how rude people can become when they're behind the veil of the internet. It shows a person's true character.

We have this old saying: "You can judge the quality of a person by the way he treats those who can do nothing for him." It holds true here. The trick is that we decent people have to continually shrug it off and continue being classy; otherwise the rude people win.

We can also report posts that are exceedingly rude and let the moderators take care of it. I don't remember all the forum rules verbatim, but I BET there is one against being rude. ;-)

Oh please stop the embarrassing virtue signaling and back slapping in the echo chamber guys! You’re sounding like teenage girls.

He’s a blatant classic example of a “nice guy”, humble bragging YouTuber, who is thinking he is covering his bases by coming with all kinds of disclaimers such as “in my opinion”, or “for me...”.
We know! This is not a religion.

He no doubt has a tonne of influence, and what he says will affect popular discourse and opinion for years to come.
You are obligated as a sane person to say the emperor has no clothes on when you see it.

You are not protecting a small, humble little guy here.
You are supporting a grownup who is selling a dream, getting a sizeable part of his income from peddling questionable advice to the masses.

Helge,
I have no dog in this hunt. I have a Nikon 5000 ED scanner, and you will have to pry it out of my cold, dead fingers. How is this YouTuber getting income from his videos? If in fact that is his hidden motive, then he should be exposed. If not, then maybe he is just humble bragging, which is not exactly admirable in of itself.

Most notable YouTubers get some kind of income from their videos. That’s no secret. It’s the add program. Some for YT and some for the content creator.
I doubt, even with his sizeable subscriber base that he gets enough revenue to make it sustainable though.
However, no one continually puts as much effort into videos, and rubber band stretches so little content over so much time, without getting something for it.

Sorry to say it, but there is a good chance that you will outlive your Nikon scanner.
Though they were build to a high standard, they are made to last ten years or less.
You can make them go three times that with service probably. But service, and compatible OSes with machines capable of running them will dry up soon.

All the stock revival, new cameras and film holders are fine.
But what we really, really need right now, more than anything, is a good, cheap and last but not least flexible scanner.
Good and cheap are not as mutually exclusive as they once were.
It’s very easy to imagine a simple mobile tech CMOS based scanner that would kill a Flexthight in most ways.
And flexible is also extremely important. There are some OK ish 135 scanners out there, but they can’t even scan half frame or square Robot frames, let alone X-Pan.
Scanning medium format, 126, 127 and large format is not just “nice to have”. It’s something most people will need more than once, and something many will need most of the time.

There is a potential upgrade for the V800. It would consist in replacing the higher resolution lens to scan only 4" (or 6cm) instead 5.9". Right now film flatness is better ensured thanks to ANR holders so that enhacement may make sense.

Present design resolves 2900 effective dpi in the Hor axis, so with a longuer focal covering only 4" in theory it would resolve 2900*5.9/4 = 4277 dpi effective, the drawback is that only three 35mm film strips would fit in the 35mm holder, and only one 120 format strip.

Carriage drive should also be improved, I guess.

Also electronics can be enhanced, it is (amazingly) a 2006 product and I'd say that after 14 years there is room to make a cheaper/better electronics design with higher integration: A single board with less components, with lower connectivity costs. A new design should also be able to perform Multi-Exposure in a single pass, making both HDR exposures before advancing the carriage. Perhaps cost reduction in the PCBs manufacturing may pay for the design update.

Presently sensor is not limiting resolving power, of the 6400 dpi on sensor (it is +40k pix in 2 rgb rows) only 2900 are resolved horizontally.

In a perfect world the V800 substitute would incorporate a 3rd lens, displacing the lens holder also in the other direction.

Also Plusteks could be improved with a larger sensor with more pixels.

Problem is lack of competition and reduced market size, but perhaps if that "film flourishment" stays those manufacturers may make upgrades, now Hasselblad has abandoned and the related (small) Pro nich is not exploited.

If Epson/Plustek do not react in time with a convenient/faster/better design the future trend may be DSLR scanning.

A problem with ‘DSLR scanning’ (and many dedicated film scanners) is holding the film flat and square to the optical axis. This problem becomes more critical (limiting) as you improve the lens and image sensor.

This is why the Imacon/Hasselblad Flextight ‘virtual drum’ design was so good: by curving the film, a perfectly straight line was assured across the curve, and so grain-sharp focus across the whole frame was guaranteed as long as the line was perpendicular to the optical axis.

Perhaps that method, if it’s patented, could be licensed from DJI for a modest fee. Why would DJI decline now that Hasselblad is out of the scanning business?

I agree scanning is a major problem for film users. You see that by the lengths people go to to get antique Pakon scanners working on modern computers, and the success of VueScan (imagine the money that has brought in!), and the fact that many scanners (Coolscan models, Minoltas, etc., routinely sell for more than their new cost 15 or 20 years ago – even though they’re ticking time bombs or need Windows XP in many cases).

Consider that:
  • modern integrated electronics over a USB-C interface would take care of scanning times
  • off-the-shelf (or nearly) Chinese optics would take care of the lens, even if you require an excellent one
  • a modern sensor, if necessary an off-the-shelf camera sensor, could be pressed into service with better signal-to-noise and read-out speed than any line CCD from the Coolscan (or Epson V800) era
  • the scanning software could (and should) be brutally simple (cheap to develop): no-one needs to edit or even crop in the scanning software today. All it should do is spit out a Raw file. And the DNG format is freely available for that
  • easy software stitching might open up new possibilities for improving image quality in a low-cost scanner, for example having the lens and sensor cover only a 35 mm frame (for best quality) and do multiple passes for medium-format
  • etc.
Making something like this would be an awful lot easier and cheaper today than it was 15 years ago. That’s why it’s such a mystery to me that no-one has done it yet.

The glass negative carrier of the LS-9000 is reasonably effective at holding the film flat, not withstanding any random outbreak of Newton's rings. However as you're probably aware using the Coolscan 9000 for any kind of 'volume' work quickly becomes extremely time consuming.

YouTube/Google pays people for allowing ads to run on their videos. That is why you hear so many of them begging for us to "Click like and Subscribe" Clicking 'Like' teaches YouTube to recommend more videos from that channel to a viewer. Same with Subscribe.
That is also why some YouTubers have these click-bait video titles, like "Is Micro 4/3 dead?!" That causes a lot of people to click into their video, which in turn gets them ad revenue. On a popular channel with thousands of subscribers, that revenue can be substantial enough to be the person's only job. Especially if he lives in his mother's basement.

Now and then, you see the rare video without ads enabled. THOSE are the guys who are doing it for the joy of doing it.

Yeah, I don't like the guys style and I'm expressing my dislike. Since when did that become wrong?
Personal style and method/argument are not always separate.

His style, mannerisms and ideas tells us something about his stringency, knowledge and whether he is in general a person to take advice from, and about him being a poor "role model" to others.
His skill as a photographer and general level of knowledge is directly and tangentially connected to his ability do tests and evaluate the results.

I have a feeling we are dealing with callout culture here..?
Ad hominem attacks would have been seen as bad style in an academic journal. But this is not an academic journal.
And sometimes even in academic circles, ad hominem is necessary to explain the level of doubt cast on results, however regrettable it is to drag a researchers name through the mud.
There are different kinds of ad hominem.

When I say "it's beside the point", I'm suggesting that only looking at his conclusions alone should be enough in itself to tell you he is at best idiosyncratic.
But taking a look at the whole person and style of the video, will clarify some things in ways that should not be victim of mistaken continuum fallacy like reasoning.

While I don't wish to comment on the particular individual under discussion, I haven't found that much good content on YouTube in relation to photography. Surprisingly the dpreview videos seem pretty good, with reasonable presentation and competence. Otherwise it is surprising how lack-lustre some of the work is over there. I suspect the main point is to produce video that generates clicks and advertising revenue rather than good photographic content.

A. There is probably close to zero possibility that Epson is ever going to significantly touch the V800 series.
B. The upgrades needed would entail an entirely new design anyway.

The Epsons are far too expensive for what they offer, they are an old golden egg the company is just sucking dry, and getting ready to chuck when profitability drops too low.
They have a setup production line they run once in a while. Upgrading or changing that would take a leap of faith uncharacteristic of a big established entity.

I'm thinking line CCDs are getting scarce and expensive to make.
Probably they are:
A. Being fabbed on old legacy process equipment, that is getting worn out and getting increasingly expensive. Possibly what Epson and Plustec is using is old stock from finite sources.
B. Being run on very expensive custom fabs, for specialty purposes (scan backs, military and astronomy etc.).

Using a small non Bayered CMOS sensor with variable backlight, being close proximity footprint stepped or slid over the film, would be better because:
  • They are cheap, available and readily compatible with current ISAs.
  • They have no limits in terms of width (or length) and number of exposures.
  • They are small, so optics can be small and cheap, they have a big DoF, in combination with the small optics and you get a little of the benefit of the small aperture of the drum scanner, in that it minimises global veiling flare and blooming (which is already better than CCDs) between different parts of the frame.
  • They are more fault tolerant, especially with overlapping exposures. A single spec of dust or a dead sensor site, on the sensor is not going leave a line covering the whole image.
  • It would give better black and white scanning,
I'm thinking ditch the cabinet entirely. You don't need a plastic box to house what is essentially a microscopic camera.
Have the micro camera on a small probe that can be freely placed anywhere on the film or glass covering the film.

I'm thinking having no, or minimal motors and complex mechanics, would drastically cut down on costs of the whole thing. And equally drastically increase flexibility for different formats and uses and reduce bulk.
It would entail a bit more user interaction with the scanning process, but that would be entirely in line with the rest of the photographic process and not be excessive and certainly not more time consuming at all.

You might, or might not need to put the probe on a pantograph with rotary encoders, or use some other means to establish absolute position.
This might especially become necessary with larger formats.
Otherwise you'd use generously overlapping exposures to establish continuity between exposures.

The backlight might consist of a simple LED for focus confirmation/orientation and a standard flash tube with changeable filters in front for the actual exposure.
A flash is preferable for the cleaner brighter light, incidentally containing also a portion of the IR spectrum for use in ICE like correction.
C41 orange mask correction is meant to be possible with a single Wratten like filter, so it would be a matter having the appropriate colour filters on a rotary tube disc in front of the light source.
RGB LEDs might be cheaper though.

The holder might consist of a shallow tray that would be filled with scanning fluid, so the tip of the probe, with the front element is submerged in it while scanning.
This would cut down on optical index change refraction, and vastly simplify good inexpensive optics in front of the sensor.
It would also mean using glass to hold the film flat would become trivial. Alleviating Newton rings and making the glass very little of an optical problem.

But Epson has a powerful industrial product development department that makes easy new reliable designs. Core know-how fields are supported by a legion of specialists that are very well coordinated, so they can issue complex new designs at a very fast pace. Anyway any product has to be profitable. I can't say if they will upgrade the V850 in the future, of course, but they have all the synergy that it would be necessary to make it easily.


The Epsons are far too expensive for what they offer

It looks that you are not aware of the Epson capabilities. The Epson resolves 17000 pixels in a single pass on the scanned width, with a unique 40k pix sensor no other flatbed has, and with lenses able to resolve those 17000pix. In the Hor axir it resolves 2900dpi effective in a 5.9" width.

A recent serious test demonstrated that for MF and up the V700 equals Creo and Scanmate 11000 drum results, if you want I give you the details.

For 35mm it is true that we have better/choices choices, like the Plustek 8200, but for MF and up the V700-V850 has been best value for decade and an half.

If they had any intention of doing it, they would have done it years ago.
As said. they are coasting on fumes and are probably happy that way.

Big corps feel no need to cater to the long tail segment of consumers. That is how big guns are taken down.
Xerox snubbed small Japanese copier producers, and later largely snubbed all the computer technology they developed in the 70s, that you are using crippled watered down versions of right now.
Microsoft snubbed the smartphone and the importance of their own deservedly bad image.
Kodak didn't know where to put their eggs at the right time. They had all the best digital sensors and associated technology, but didn't use the last (million) bucks in hiring world class enduser software people.

I'm not saying film is going to explode like a new technology, but with a great cheap scanner, it will very suddenly become a hell of a lot more accessible, affordable and fun for people being hesitant now.
Sure, Epson has all the necessary tech, people and cash buffer to do it.
But they won't.

You don't shoot medium format or large only to use a tenth of the resolution.
It might be OK for proof and small prints. But for end use you almost might as well use 135 and a dedicated scanner or DSLR rig then.
The lens in the Epsons is not very good. Real resolving power has been shown to be wayyy off specs sheet claims many a time in tests.
Yes, I'd sure like to see the test you mention.

The problem is not so much the sensor (even if I think a CMOS array sensor would be more appropriate today) it's everything else in-between.

Oh please! Explain exactly what “toxic” means.
Apart from it being a favorite empty buzzword of the chronically offended.

Your behavior in this thread has mostly been toxic to put it politely. This reply from you is yet another example of that toxic behavior.
I suppose that you can keep it up see and hope people shy away from your bullying but, I'd suggest that you just tone it down and try to get along with others.

In this thread, for example, you could have simply stated that you did not like the guy’s style and went on with an explanation of how his methods could be better - or whatever. This would have been a more powerful and useful approach than spewing copious quantities of invective.

Present film usage is a surprise for many manufacturers, but this is a 2006 design, see that schematic from service manual: it uses use extensively 74VLC245A parts !!!




The V700 has around 11 boards inside... I design PCBs... and I use 74xxx245 parts, but I think that Epson today would include a single board with different parts. My view is that if "film flourishment" continues then Epson may release an enhanced design, those 14 years in production are a really long term in the electronics market.

Yes, I'd sure like to see the test you mention.

It's not so much the resolution problems as the god-awful MTF performance - and there are high quality tests that show just how bad the performance really is. The only time an Epson might do better than a high end scanner is when the operator is so inept that the idiot-proofing of the Epson saves them. The claims about being able to equal high end scans via magical sharpening routines are just plain dishonest & based on partial, manipulated data of high contrast edges & use web compression as camouflage. Low contrast areas with fine detail are where the rubber hits the road MTF-wise and the Epson defenders hear the song of the Sausage Creature as their (apparently incredibly delicate) egos meet the tarmac. A lot of the defense of Epsons and similar flatbeds is down to sour grapes/ envy.

As it is, the company with the best potential mix of tech & knowledge is Fujifilm - if they put a higher res monochrome CMOS sensor into the pixel shift setup & R-G-B-IR LED backlight of the SP3000 type of design (and added LF capability) rather than the 1500x2000px CCD & let you get linear un-inverted 16-bit output from it, that could be a game changer.

Lachlan, you are totally wrong, For MF and up the V700 / V850 is a solid scanner that in the right hands it delivers practical results that totally match drums and high end flatbeds, specially for MF and up. There are some jobs, (say 5%) in what a drum provides an slight advantage, but not much.

If you want I can provide smoking gun type evidence about that, and many examples of clearly forged side by sides throwing lies about the V700 because it was a hard competition for scanning services and pre-press gear dealers.

The V700 it is not a Pro scanner, a Pro scanner operator scanning all day long wants another thing, but at home it can deliver totally Pro resuts with some effort.

Do you want to see the evidences ?
