PHOTOOG Photography writings by Olivier Giroux


Holy cow, I'm excited by the 21mm Distagon!

There's a brochure PDF now, but no charts yet.

If you've been reading my blog for a little bit (nearing post #100!), then you'll know I've linked to this Distagon 21 MM PDF a couple of times (1,2,3,4). Most recently that was in a post discussing the 18mm Distagon's launch. I wasn't very excited by that lens, and hoped the 21mm would be resurrected instead...

Well I didn't have to wait a long time. :^)

I'm just ebullient with excitement now!

The optical design did change a little bit, see the rear groups below. I expected that after Zeiss had replied to my questions earlier this year. They said ROHS rules were preventing them from shipping the previous design as-is.

Here's a comparison:

New design: 16 elements in 13 groups.

Old design: 15 elements in 13 groups.

Let's hope the new design lives up to its predecessor's reputation. Can't wait t get my hands on the charts. I bet Lloyd Chambers will get them soon.
