Certainly not all. There are quite many of them which are genuine
inhouse designs IMHO. Also, many lenses from many manufacturers are
just derived from earlier lenses, as are the USSR (not copies,
derived). Like most primes, etc. It's the tweaking that makes a
perfect lens often not a completely new design. Most 50 primes are
very similar gaussian lenses, etc... The same for fabled 35/3.5 SMC
which is the simplest wideangle possible, a simple Tessar with large negative
element up front, completely same design as several cheapest 3rd party 35mm lenses
out there. It's the tweaking that makes it good. And in the USSR, the
Maksutov catadioptric design was made, too, which is among the best
for mirror lenses.

Well, I got on a little cardbox soap here ;-)

Good light,

Vs: OT: Yashica MF lenses

2002-04-06 Thread Raimo Korhonen

Yes - the Zeiss Planar is the most prestigious, but optically the best is Schneider 
Xenotar - and it is cheaper. Yes, I have owned Rolleiflexes with both lenses. I have 
to agree about the screen (and split-image rangefinder).
All the best!

BTW, I have seen several Rolleiflexes (I have and used some older
ones, prewar) but Yashicas are clearly better in their focusing screen. Yes,
Planar is better than Tessar design by many degrees, but so is the
price. If I bought a Rollei (a 2.8 Planar tempts me, in such a small
box. Although I love the early, smaller Standard Rolleiflex '35), I
would have the screen changed to a beattie/microprism. The original
screen really sucks (sorry Wendy, but it's been long time somebody
used this word g). Why did Franke und Heidecke they put such stupid screen on 
otherwise great camera ?!?
