It's quite good, isn't it? Holds up well against the K5 IQ wise, and noticeably outresolves the Kr.
If you download the JPG's and look through a viewer that allows compare such as Farstone the Canon is way sharper than the K-5

The trouble is Pentax don't really have a standard lens suitable to do this kind of test, unless the 50mm f/2.8 Macro is still available? The 50mm FA f/1.4 isn't the sharpest chisel in the toolbox

The test should also be done at f/5.6 these kind of lenses (apart from the macro fall off at f/8 )

I have my suspicions about this test. The Canon looks sharper, but the Pentax doesn't look in focus and at f/9 that takes some doing

Against the K-5 it's the same?

The Exif according to Photome does not recognise the lens on the Pentax, so I suspect it's a 50mm f/2.8 Sigma

I posted a link yesterday on another thread to some photos taken on 6x7 Portra 160VC the shadow detail is really impressive. Larger pics are at the bottom of the page. Looks an ideal way of doing architectural shots.link

If you look back at cameras of the past, none of them would have been built by marketing or accountants and then where would we be today

Well some would have at least been made such as the Kodak Instamatic's That's a marketing term if ever I heard one "Instamatic" which means it isn't Instant. I suppose they made it from Plastic to keep the Accountants Happy if they hadn't had such powerful Marketing and Accounting they wouldn't be where they are today??? Where are they today apart from marketing cheap batteries :

Kodak did let the Engineers run wild once and they made the best lenses ever made regardless of cost the Kodak Ektars of the 50's and 60's much better than anything the Germans could make

Never seen any results from v2, but, v1 was very well made and I suspect v2 involved a bit of cost cutting. The chrome ring was 1st to go

There are probably 2 types of 6x6 lenses, some not too sharp and some that are exceptional. Generally lenses are designed for the highest MTF wide open, sometimes they may just use an old design such as Tessar.

My Bronica S2A 75mm Nikkor lens tested out at a maximum of 140lpmm the same as my Pentax A 50mm f/1.7. The lens on my Koni-Omega 6x7 went right of the scale

Some Koni-Omega scans (not mine). Scroll down to the larger pics lower down the page.

The extra 1 Zone on Ansel Adams Zone scale for 6x4.5 and greater comes from the film/film development and not the lens.
Look at the 1st and 4th photos on the above link... under a bridge in bright sunlight and all the detail recorded.... you would have to resort to HDR on Digital for that 1/15th handheld as well

They seem to sell quite well and for good consistent prices, because of that I would expect that you would get the same price for UK ONLY SALES.
