Hi Magus,
Thanks for the kind comment.
I originally had the same view of the 28 Cron as you did. As you know, I like the rendering of the 35 Lux ASPH much more so than the 35 Cron ASPH. To me the 35 Cron is too sharp, too contrasty, without smooth transitions and can block-up in contrasty light (as here in AZ). I am relating comments about the 35 because it will apply to the 28 as a reference point.
Upon purchasing the M8, I really needed to have a lens in the FOV of a 35. I therefore got the 28 Cron based on looking at a lot of photos from others.
In actual use of the 28, I have found it to really have very rich colors, textures, and a 3D like rendering which is not plasticky at all. However, it is very dependent on the film type that you use. When used with a low contrast film like a Portra NC or a chromogenic B&W like XP2, I really came to appreciate the lens. (Remember some similiar comments you had about the 35 Cron with different development and printing. My earlier 35 discussion is to basically portray that the 28 is a very similiar situation, but is a superior lens to the 35 Cron ASPH.) Another advantage to the 28 Cron is its truly amazing resistance to flare.
In use with the M8 and the profile that I made for C1, it is really turning out some beautiful files that are smooth, and rich both tonally and with detail. With proper exposure and film selection or profiling on the M8, it is very much to my likes.
If I were to expand on my order for choices purely on image qualities today, it would be:
1) 50 Lux ASPH
2) 75 Cron ASPH
3) 28 Cron ASPH
4) 35 Lux ASPH
5) 50 Cron
My 50 Cron is one of the "limited edition" screw mount remakes, that goes on my M5 with the adaptor but really shares my iiig with a perfect 1956 50mm 2.8 Elmar.
Best,
Ray
