I can't give an actual resolution test, but I can dig up the negatives from the couple rolls I scanned on the old machine a few weeks ago and rescan to compare detail levels. claimed resolution is double that of the old scanner (Agfa Arcus 1200), = 4x pixel count. Shouldn't be too hard to compare, I have a couple negatives in mind that have considerable sharp detail.
would be great to see.

If could check how the two scanners perform given vastly different resolution claims, we would at least know the 'fudge' factor
associated with the flatbed scanner resolution.
I'm also guilty of stuff-lying-around as a basis for solutions. For people who don't have such stuff, it represents a fair amount of gear, money and time. It depends how badly you need to digitise negatives and slides compared to their traditional means of exhibition. For someone who shoots film exclusively and regularly, all forms of digitisation are slow and the resulting print will carry artefacts of film and digital production. The biggest breakthrough would be some means of automating the process, so each frame doesn't require individual attention.I set up my duping "platform" from existing stuff I had laying around.

The important thing about film is that I get a negative …
I really don’t see what you tried to prove or show in the above?Okay, change of plan.
Apparently, the only film carriers available for the 4870 I just bought are modified 4990 units, at about $127 each (vs. the $70 plus shipping I paid for a set of four -- 4x 35mm 6-frame strips, 2x 120 1/4 roll strips, 2x 4x5, and 12x 2x2 mounted slides, masked for 35mm frame). Looking closely at the modified units, it was obvious what mods were made -- they took off the standoff feet, and then removed the alignment tabs on the user's right edge. Conversion obviously requires sophisticated tools -- converting the 35mm carrier took me about five minutes, with fingertips (the feet have clip latches accessible from the top side, just squeeze and they drop out), a folding knife I carry every day (to score the alignment tabs so they break off cleanly), and the file blade of my Leatherman multi-tool (to smooth off where the tabs were removed).
With the conversion completed, I found the auto focus apparently succeeds, and got what appears to be a correctly focused scan. Here's a 1:1 crop comparison, all from same negative frame.

From the Agfa Arcus 1200, original glassless carrier at fixed-focus position (pardon the apparently underexposure, this is cropped from the raw TIFF scan rather than the auto-corrected JPG). 1:1 crop.

Epson Perfection 4870, modified 4990 film holder on bed glass, autofocus, 4800 ppi. Yep, it's 4x the size, 16x pixel count. Cropped from JPG (hence exposure corrected).

Epson, same crop as above, 2400 ppi.
This all stems from the discussion about how "easy" it is or isn't for a new film photographer to digitize their images. Obviously, if you're sending your film out, you almost can't avoid getting a DVD or thumb drive with lower resolution scans than even the Agfa Arcus example above. Digitizing doesn't get any easier than that, but if you don't live in a major city, you probably don't have a local processing lab, so you wind up sending your film hundreds or thousands of miles to one of the big labs that advertises online. Cost will be close to $20, including priced-in postage, to get your negatives back along with the scans (else why both with film, just shoot digital in the first place), a little more to get higher resolution scans, even as good as the Agfa scan above (just under 2 megapixel from a 35mm frame).
This shows that, for about $200 (one time) and a little research, you can get 8-ish megapixels from 35mm even if you're downgrading your scans to half the nominal optical resolution of the scanner. At full optical resolution, you're likely to wind up doing some digital grain reduction (most casual users will do that anyway, along with automatic dust removal). But once you know you need to modify the film carriers, and how easy it is to do, along with learning to process your own film (also pretty easy, and you don't have to spend the money for that equipment at the same time you buy the used scanner), you can shoot film for a couple dollars a roll above the actual cost of the film itself, and the scanner pays for itself in a few months.
So, "easy" is relative. IMO, it's both easier and cheaper to obtain, set up, and use a flatbed scanner than a quality digital macro setup, with either slide copying attachment (only works on 35mm, remember, and requires you have a compatible camera body and lens) or copy stand, macro lens, and backlight source, and unless you've got a professional eye, you'll probably never be able to see the difference in the final images (certainly not if they're displayed on a common computer monitor).
I send my film to The Darkroom, and get my film developed plus high resolution scans. If I want prints I can get silver emulsion prints too (I have a few and they turn out well).

I'm not sure is $30 and 10¢/g for plastic and printed at home or at your local public library like mine is affordable, but. the more things change, the more they remain the same.
I was genuinely curious, because I felt it wasn’t clear at all.
BTW, I recently watched a Nick Carver Youtube video that compares drum scans, Epson flatbed scans and digital camera scans. I love his photography, and he makes a good living at it. Might be worth a look.
Ok, I had a bit of trouble finding the post you replied to.Okay. I'm sure it was clear to the person I posted it for. Aside from being no faster (in fact, scanning at higher resolution is slower, as well as the old USB connection being a good bit slower than the SCSI my Agfa ran on -- offset by ever-falling availability of SCSI cards to fit this year's and next years motherboards), this scanner is much better than the old -- better dynamic range, 4x resolution (= 16x pixel count from same negative, if wanted), handles silver-image negatives better, offers automatic dust removal in Vuescan, doesn't require pulling out and safely storing the bed glass to scan film, autofocus or manual focus adjustment, and is significantly smaller/lighter than the old one. The only thing I don't like by comparison, so far, is that there's no counterbalance spring in the lid, so it won't stay up unless it's tipped back against the hinge lock -- and that's just a matter of developing the habit of opening it all the way.
Please don’t continually draw the mildly offended card.When I bought the Agfa (2003) it was the best scanner I could afford.
Same is true of the Epson I have now (4870). I'd love to have a 700/750 or 800/850, but they're hundreds of dollars out of my budget -- and according to you, are still crap.
I have had (not sure if it still works) Epson v700, I was ok with how it handled to scan my rare medium format shots, but was total pain and time
drain for 35mm. Every time, back then, when I enabled the ICE feature, it took ages.. and something did not work after my windows OS upgrades...
This was about 8-9 years ago or so.
I was hoping by now this whole area got significantly improved, but even with your skill and passion (which are way above average consumer) -- it does not look like we moved
far.
Obviously you missed this whirlpool of a thread:

I’m not so sure he actually makes that good of a living off of his photography. He’s good at making it appear that way though.
He strikes me as just another Matt Day jam band.
Another YouTuber I have no inclination towards.
No, why waste time and energy on that shit‽ I just avoid watching him.Haters gona hate and it's obvious you hate this guy. No idea why. Sounds like a bit of jealousy?
