When Cosina decided to discontinue the best selling lens of it's entire "SL" line of lenses for SLRs, I was disappointed (and a bit confused). A couple (probably three) of months after Cosina's discontinuing of the Voigtlander 75mm f/2.5 SL, Pentax announced a new Limited, the DA70mm f/2.4, disappointment turned to suspicion that maybe Pentax had licensed the earlier discontinued Voigtlander 75mm design; the FL and apertures of the lenses are both fairly close (2.4 vs 2.5 is almost nothing) too. At that point I couldn't get my hands on an image of the new DA70's lens formula, so I waited for Bojidar Dimitrov to update his site, which he did, and here's what I got:
Seems as though my thinking was right. Pentax seems to have "flattened" the design a bit, but otherwise they look identical.
So now we have a Voigtlander SL lens with SMC coating and Limited metal jacket. Strange and interesting beast, the V75 I have has some great properties and can compete with the 77 save for aperture and skin tone.
If Pentax drops the price a bit, I'd be interested, only $100 or so less than a 77 doesn't make it too attractive for me, especially when the 77 can still be found brand new.
What do you folks think.
Cheers!
