Hi Magus,
It was a true dilema, but only on the M8.
The film side was very easy. (My 35, 50, 90 won out. I never really liked the 90 focal length before, but have come to like it and "see" shots with it also.)
-------------
The M8 was harder with the 1.33 crop.
The CV15 is just small and handy. It seems to always get into the bag. It is also my only super-wide.
I have really fallen in love with the 28 Cron's signature. It's focal length of 37 works for me on the M8 well. However, I never did get used to 28 on film.
The 50 Lux is a favorite.
I really liked the 90 Elmarit when I compared it against a new 90 Cron. It is much lighter, smaller, easier to focus, and has a signature which I prefer.
Those three lenses make up a good focal length range for me as a 3 lens kit with the possible addition of the CV15.
--------------
On film, I love the 35 Lux ASPH. On the M8, the 46 focal length is too close to the 28/37 and the 50/66 for my use with them at the same time. I really only end up using the 35 Lux with the 75 being the next step. This works great for a two lens kit, and my feet make up the difference.
The 75 Cron is another lens that I love, but don't really use on film. My preference is to grab the 50 or 90. This is not really because of the focal length, but rather because of the proximity to the 50 frame lines in the view finder. On the M8, it becomes a 100 that is close to a film 90 and is a good combination with the 35/46 for a nice change in perspective.
Although this could change in the future, it is how I'm shooting now.
Good to see you also my friend.
Best,
Ray
