My next question is how heavily should I weight this > functionality Contax offers in my quest for a medium format system. I think that Linhoff offers a 70mm vacuum back. Most aerial cameras can be had with vacuum backs that use larger film sizes (5" rolls or bigger). To be honest, I think that this feature would only be helpful if a) you shoot 220 film - this assumes that the film you want to use is available in 220. b) you shoot at or near maximum aperture. c) absolute sharpness is a major requirement. What I mean by the last point is that a minor focussing discrepancy can ruin a whole day of aerial photography (incl. plane rental, etc), but may go unnoticed in a portrait session. I guess that I should add one more point, d) you are unable to bracket your focusing on critical shots. Again, this is an issue in a moving airplane, but not so much when you are shooting a landscape from a tripod.

I once was given two (rather old and beaten) Hasselblad 70 mm backs, previously owned by our national Department of Transport, that were modified for aerial photography. They had provisions for being used as vacuum backs: holes and grooves in a modified pressure plate, and an air outlet. No pump, but any external pump would do (yet making it to blow or suck at the appropriate moment would require some thought...). I don't know whether these adaptations were done by Hasselblad, or by the Department of Transport. Nor do i know whether or not they were a success, yet someone must have thought it needed a try. ------------------------------ Date: Wed, 01 Nov 2000 18:25:38 GMT From: To: hasselblad@kelvin.net Subject: Re: Film scan Message-ID: <58d5e5a865.5a86558d5e@eresmas.com> This is a multi-part message in MIME format. ----1bc07081355732b6 Content-Type: text/plain; charset=iso-8859-1 Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Hello all=3A I am also looking for a good-reasonable =24 scan for transparencies and negatives=2E I saw an Epson 1640 Photo with a 1600x3200 optic resolution = (42 bit colour depth and maximum density 3=2E1) with an special device for scanning transparencies till 4X5=2E Anybody has experience with this=3F Thank you=2C Rafael Alday --- Descubre lo f=E1cil y c=F3modo que es hacer tus compras por internet en Comproahora=2Ecom de eresMas=2E Haz click aqu=ED=3A = http=3A//www=2Eeresmas=2Ecom/fs/tiendas ----1bc07081355732b6 Content-Type: text/x-vcard; name="ralday.vcf"; charset=us-ascii Content-Disposition: attachment; filename="ralday.vcf Content-Description: Card for Content-Transfer-Encoding: 7bit begin:vcard n:Alday Anzola;Rafael fn:Alday Anzola, Rafael version:2.1 email;internet:ralday@eresmas.com end:vcard ----1bc07081355732b6-- ------------------------------ Date: Wed, 1 Nov 2000 12:51:32 -0800 (PST) From: Eric Maquiling To: hasselblad@kelvin.net Subject: standard on 50 anniversary 500c/m?

Message-ID: <20001102015351.26415.qmail@web3106.mail.yahoo.com> First off, lets put things in perspective. Perspective with respect to film flatness with 'Blad and other MF cameras and a comment or two about mf format to other formats. Secondly, I'm concerned that we aren't chasing rabbits that are difficult to catch. Are we photographers or are we inflating the importance of the whole film flatness issue out of proportion, because isn't it really a non-issue to the majority of people in the audience who view the finished enlargments? Now, not to ruin anyone's day, but supposedly, the Rollei 600x film backs hold the film flatter than Hasselblad, due to the clamping film guides or something or other. This is according to someone I met at a Chicago camera store with access to all the 'Blad and Rollei stock they carried at that time, who was deciding on 'Blad vs Rollei. He compared both the 'blad lenses against Rollei, and examined the chromes under a 200x microscope. He said the two were so close that the differences weren't worth talking about. However, with respect to Rollei, Schneider had the edge on the lenses he checked out. He also said the construction of the Rollei film back positioned the film plane more consistently than 'Blads did. He did not like the Rollei electronics, and heard several heated complaints from customers returning their equipment. So, he liked Rollei but didn't feel he could rely on it due to early models with quality control problems. His favorite two cameras: 903SWC and Contax T2. Oh, by the way, Rollei also has a 70mm vacuum back, very expensive though. On the other hand, do many 'Blad users complain about fuzzy pictures because the film wasn't flat enough? Perhaps anything perceived is more due to mismatching film back mechanisms against another film back that it wasn't mated to, thereby introducing differences in where optimum film placement is with respect to the lens? I still don't see or hear complaints about this. Not that it doesn't happen, it's just that I haven't seen them. 'Blad didn't get to be the most widely distributed MF system in the world by having film flatness problems, but most salesmen have cautioned me to not mix and match components for 'Blad film backs. Besides Rollei, in comparison to other MF cameras, it doesn't matter much whether the picture was taken with Rollei, 'Blad, Contax, Pentax, Bronica, Fuji or Mamiya 7 II. They all make the film flat enough. MTF curves and lines/mm are all nice and well, but has anyone ever made a demonstrative graphic example that shows the difference between say, 67 lines/mm and 62 lines/mm? You have to blow the picture up so large that it approaches ludicrousness. You have to graphically attach the numbers with an actual picture to grasp the significance, or lack thereof. I've seen this done only once with Sinar literature, if memory serves. Maybe someone knows of a web link that graphically shows this sort of thing? With respect to different formats, I think that the smaller the format the less leeway you'll have for errors in film flatness. If anyone really wants to be 'King Of The Hill', you should consider shooting large format, like 8x10. I've got 8x10 velvia chromes that leave no argument when compared with medium format. Sure, medium format can capture more lines/mm, but so what? Put an 8x10 chrome on a light table alongside a MF and 35mm chrome of the same subject. Viewers won't even see the MF. It's just no contest. Does anyone question whether the 8x10 sheet film was held flat enough against a sheet film back? Nope, never comes up. Does anyone looking at the chromes care? Nope, because the overall picture, composition, exposure, colors, etc. all work together to create a visual impact on the viewer. Film flatness just isn't that big of an issue. Your milage may vary, of course. 8-) So, what's the point in bringing this up, you wonder? The bottom line is that what we're talking about here with MF film flatness, there just isn't going to be enough difference for the average person to notice unless the print is absolutely humongous, and even then you'd probably have to point it out to him and he wouldn't even care because he's so overwhelmed by the colors, the size of the print, the composition, that what you're talking about significantly dwindles in importance by comparison. --- Simon Lamb wrote: > Michael > > Film flatness is indeed an issue but I am sure it > will not be one that > bothers the majority of Hasselblad users.
