Got the 667 a couple of weeks ago. Tend to go for medium format more and more and got a decent price for some stuff I traded in. Anyway, I have a couple of other camera's which are medium format 6x6 and decided to do an non-comprehensive comparison. Subject: Newspaper front page, smallest print 1,4mm, next smallest 1,8mm. Distance 1.3 meters - I guestimated that the smallest print would be illegible at this distance and it's simply where my tripod wound up in front of the couch. I took four shots, at 3,5-5,6-8-16. I wanted no more than four because three times four makes twelve, and I shot them all on the same film (Acros 100, because of it's fine grain and no worries about reprocity failure, times ranged from 1/8 to 4 sec).
Result judged on a light box with loupe 10x, also wearing reading glasses. Sorry, scans not available - I gave up on scanning in favour of the darkroom and the scanner is somewhere in storage.
Here what it looked like with the loupe:
Rolleiflex E2, Planar 2,8:
At 3,5 unable to read the 1,8mm text.
At the 5,6 1,8mm partly legible.
At 8 1,8mm legible, 1,4mm not legible.
At 16 both texts legible.
(I found this al little surprising as I would expect some deterioration at 16, unless focussing was inaccurate. However, I have previously tested for this and the focussing screen seemed accurate).
Yashica 24, Yashinon 3,5:
At 3,5 1,8 text partly legible, slightly better than the Rolleiflex at 5,6...
At 5,6 1,8 text legible, 1,4 text partly
At 8 and 16 both texts legible.
(No surprise really, I've always found this one to be stingingly sharp. At the 40 euro's it cost me the word undervalued springs to mind)
VL 667: Both text legible at 3,5. Slightly better definition at 5,6, again slightly better at 8. At 16 it's hard to tell the difference with 8, it either equal or slightly less.
So... The 667 already has a reputation for sharpness and I'd say rightly so. No problem using it wide open. The Rolleiflex is less sharp than I would have expected. Not going up for sale though - it sometimes produces a kind of threedimensional look I immensely like. Which is just to say, I do realize it's not all about sharpness...
