Ahhhh... the GF55/1.7. Very nice images in these pages from it. I prefer the OOF rendering and also FOV of the Mitakon 65/1.4 but must admit the strengths of the 55/1.7 (sharpness, control of aberrations) cannot be denied.
I really wanted to like the GF 55/1.7 when I owned it with my 50sII but couldn't stand the focusing noise and "chatter"/hunting that it would often do, even when I had set focus to manual mode.
I really wish Fuji had included the LM design for AF but I guess couldn't for size/cost/technical constraints?
I'm currently shooting with the 100sII. For those of you who have shot this lens with both the 50sII and 100sII, does the 100sII do away with the random chatter/hunting?
Thanks,
Peter.
My solution was to shoot the GF 80mm f1.7 for awhile, so when I went back to the GF55, it didn't seem so bad, and at least, my shots with the GF55 were mostly in-focus.
As a retired engineer who designed servo systems very early in my career, I am a bit perplexed by the crudeness of the Fuji focus system - even with my GF110 with the LM. Modern focus systems utilize phase-detect interfaced with contrast-detect for fine-tuning. It is my guess that Fuji has not figured-out how to effectively interface the two systems. Nikon/Canon/Sony have figured-out how to instantaneously move massive lens elements in near silence for perfect focus in some of their larger lenses.
For me, I have become accustomed to the annoying sounds from the GF55 and it does yield perfectly focused shots most all of the time. I certainly wouldn't complain if they released a Version II with a LIM and technical improvements, however.
