Loving my ZM 25/2.8

Fabulous image qualities in that picture, and even to a gay man's eye, a beautiful subject. I'll have to try using my 25mm wide open like that. I've been using f/5.6 mostly, but you don't get that lush OOF with the lens stopped down, even just 2 stops.
 
Absolutely fabulous! I love the lens too, but I have not taken anything that nice yet!
 
CV and ZI?

CV and ZI?

Hello:

Very good! I've a question-do you have experience with the CV f4 25mm? Is f2.8 ZI better at f5.6/8? My f4 cannot match your shot of course.

Frank, the 25mm Biogon ZM is one of the highest resolution lenses ever produced commercial for 35mm photography, so it probably is better until f/8 when diffraction begins to limit both lenses' resolution. But I've never used the Skopar 25mm, so I'm saying this based on Zeiss' MTF measurements and my own use of the Biogon 25mm compared to Nikkor 24mm/2 AIs and 24mm/2.8 AF lenses. While those lenses are very good, the 25mm Biogon is just stunningly better. Unlike the current Skopar 25mm, the Zeiss 25mm is RF coupled (to 0.7M, but like the Skopar, decoupled scale focus is possible down to 0.5M.)

With the 25mm ZM lens at f/5.6 details are crisp over a huge depth of field, all the way to the very corners, for landscape/cityscape photos near infinity. Tonality is very smooth with fine grained films, and color rendition is gorgeous, with very realistic saturation. It's very flare resistant. I had not realized it was capable of such subtle background blur until I saw Tripplefinger's wonderful portrait. I definitely want to explore this aspect of the lens now. It's like a whole other world I never thought to explore. Sometimes I get trapped trying to keep everything in depth of field in a scene, ignoring when it might be interesting to have more blurred areas that can make the subject pop!

The size of the Biogon 25mm lens is going to be a huge difference to the Skopar, with the Biogon being much larger in length diameter and weight. It's long for an RF lens, but not too huge, projecting 47mm forward from the lens flange/camera body and taking 46mm filters (narrower than the Leica 24/2.8 ASPH with its 55mm filter size).
 
Thanks for posting this photo. It is beautiful. My interest in the lens you used comes as a distant second to the photo iteself. Please post some more!
 
THanks Frank, I have not shot the CV 25. I do have the 15, which is lovely, but does not match the color or tone of the ZM 25

Lovely photo with amazing sense of roundness, texture, 3-D, that feeling of being right there. Like I could reach into the photo and brush that lock of hair out of her eyes! Very impressive...
 
Wonderful shot. I just received my 2.8/28 Zeiss and while I am working at a novice RF level (and don't have a 2.8/25 in my kit), look forward to learning the wide angle ropes from the pros on the RFF.
