Advantage of 6x8 over 6x7?

[Brett Rogers]

You should ask what the benefit compared with 6x9 is !
There is one like the statements of some with 6x8 mentioned before.
A little more resolution one should Not forget.
The ideal format is 6x9 with 120 film.
Thats fine - But what camera is the next
question?
And thats the problem - what camera ?
I personally just know the Fuji GSW 690.
And GW 690 but that should be all ..
The rest is manufactured in the 20th and
30th.
Fuji has not a system to change the lenses with GW/GSW cameras.
And that is the rule of 6x8 today because
there are no modern cameras to 6x9.
Come and have a look from his point
to 6x8.
There are not many options with cameras
to 6x8 exept Fuji and Mamija.
But there are some - that is the advantage of 6x8 : 6x9 = NO options.
I decided to 6x7 because Pentax has a very great system.
But 6x7 is sometimes a problem.....
4,5 x 6 is also ideal from my point of view but it is to smal - at the end you are standing still with 135 films.
That is indeed a positive alternate ..
Have a right choice with the right Format to you.
In case of 4x5 inch it is the same as 6x7.
But here with 4x5 inch it is not a question
to format - you never care about - it is just the (sometimes) unreachable quality of 4x5 films.
More quality you will (often) see with 5x7 and with 8x10.
At the very end some Apug members swear on 16 x 20 films ...?
I want to ask what kind of pickup is the
right car to this equipment.
But before lets talk about 6x8 here.....
A realy nice discussion - I like it..
Never the less it is from 2010...

Linhof will still sell you a camera and 6x9 Rollex back for their various bodies, if you're willing to pay for them. Granted, the list price for a new Super Rollex is over 1200 Euros, and you may not wish to pay Linhof's prices for their equipment. That's fine, but it is an altogether different thing to claiming that there are NO options presently available for 6x9 today (which is what you've said).

Sure you said it Brett - "Linhof" !!!
And you might be also right.
Obviously some photographers are not willing to handle such big equipment like
Linhoff's just to shot 6x9 ?
But not me - I am willing to transport biggest cases - if there is only a small profit.
In case of the Rolex back I informed me at about 2004 because of the fact that
4x5 as a normated standard gives a option to some cameras with the 6x9
back.
But I found out there is a much better option with the various format back.
4,5 x 6 up to 6x12 ! I tryed to get it on ebay to that time the max. I tryed to pay
was $400/500 if I remember correct.
But with no chance at all - it should cost
over $ 1400,- at the end.

PS : The Rolex Back is a little bit tricky from my point - because of the 4x5 lenses.
Best in use to tele shots / not easy to have wide angle shots ?
But tele shots are the classic domain for
135 cameras - never the less you may have also many options with 4x5.

Um, er, ah, Trendland, I have a funny sort of Cambo camera. 2x3 front standard, 4x5 rear standard. Tapered bellows (two, bag and pleated). And I have a 2x3 Super Rollex that fits a 4x5 Graflok back. Cost ~ USD 125 delivered from France. The rig works with all of my lenses. Shortest is a 35/4.5 Apo Grandagon. Longest is a 900/10 Apo Saphir.

The roll holder has nothing to do with which focal lengths can be used. The camera's minimum and maximum extensions are what matters for that.

Roll film holders have real pros and cons. Some are very well made, some are not. Some are just too heavy for light field cameras and prone to tug the film plane out of focus. The slide-in one's won't fit most cameras. If you want an all-metal system, Horseman is every bit as well made as Linhof at a much lower price, but with less bellows ext in the Technical camera category. Either way, you're talking about view camera technique rather than ordinary MF.

Perhaps I made a misstake but if your format is 4x5 inch and you use a 6x9 Back the focal lens will not change - right ...?

If you use ( just for example ) a Rodenstock 210/5,6 Sironar N the focal lenghts is in the near of a standard - like one mans eye ( from optical concern of view ) we all know this from 50mm lenghts with 135mm cameras.

Now your format changes to 6x9 ( but the focal lenghts does not change - it is also 210mm with 6x9 ) but the angle of your shot will change - right
...)

you will need something in the near of half 210 mm because you crop your 4x5 format with a 6x9 back ! 105mm should it be to have the same angle
to your shot.

Therefore I mentioned : It is fine to Tele Shots because a 6x9 back will shorten the angle of your shot - it makes a Tele from a standard 4x5 lens.

But if you will have a wide shot you should have 45mm - 55 mm to 6x9 ( not so easy from my point of view with large format lenses ) ?

youst look to price lists. I just had a look to 40mm (Rodenstock HR Digaron $ 4598,-.....)


Allways with exeptions of cause - so like you : 35mm - 900mm....Um,er,ah........!

 

[Brett Rogers]

Well there are any number of used, older types of cameras that can natively produce a nominal 6x9 image or be made to do so with the appropriate back. But your comment (the one I quoted, previously) was clearly referring to "modern" 6x9 options.

My point was, (and is), that Linhof continue to manufacture and sell several different camera models, some of them medium format, others, large format with medium format capability depending on the back, and you can purchase these items, brand new, from Linhof in 2017.

I appreciate your point that fitting a medium format back to some 4x5" cameras will often tend to result in being restricted to a widest lens for Eg. the 6x7 or 6x9 ratios that yields only a normal(ish) angle of view. As someone who shoots 4x5" with an older Super Technika and also uses Rollex medium format backs on it, this is an issue I'm well aware of. But Linhof continue to make several medium format cameras that will take lenses in a variety of focal lengths able to be fitted with their 6x9 Super Rollex—so, if a brand new 6x9 format camera you must have—you may still buy one (if you can afford it, that's altogether another matter), and it doesn't have to mean using a 4x5 Master Technika at a reduced format size, either.
Cheers,
Brett

The nice thing about roll film backs is that you've still got a full 4x5 camera when you want specific shots capable of greater enlargement quality, even on the same outing, using mostly the same lenses. For example, for 6x9, my 300 Nikkor M gives the same perspective as my 450 Fuji C on full 4x5 - both wonderfully light precise lenses, but one helluva different bellows ext !

Ideed - and it is in relation quite cheap to use 120 film a back to 6x9/6x8/6x12.
And with some changes again 4x5 film.
The Most advantage is also the international standard with 4x5.
