Hi guys, first thank you for this thread. Then, I own a Canon 35mm f/1.5 LTM myself and I really love this lens. In fact it's certainly my favorite one, all mounts.
I've just found a M-Summilux 35mm f/1.4 1rst version (non-asph), so I hope I'll be able to compare them soon. Summi is pretended to be quite soft wide open, but to me it should be better in B&W than the Canon 35mm f/1.5.
After 18 months using it in every day use, I find the Canon not so good in B&W, compared to the 35mm f/2 for example (a real Summicron killer with incredible bokeh WO). But for colours, with slides films, I must say I just L O V E the Canon 35mm f/1.5 LTM. I noticed the same thing with the Canon 50mm f/1.2 LTM : very 'milky' with flare in B&W at wide apertures, I did not like it very much, but with colors...
Dante Stella, who
seems to like Canon LTM lenses, wrote :
We accept that a F/1.4 lens is tougher to make than an F/2.
Probably easier with a longer than a shorter lens. There are several brilliant choices, for instance, in an 85 /1.4 lens: Contax Planar, Leica R Summilux, Nikon, Minolta... they are all expensive, have fantastic 'build quality', and deliver wonderful, EQUAL, images. And all must be used wide open to show off their unique image properties: a fine F/2 lens is as-good-or-better at any aperture smaller than F/2.8. And I'll suggest there is less difference between F/1.4 and F/2 performance at 85mm than at 50mm, and less at 50mm than 35mm.
I'm sure he's right, and comparing the 50mm f/1.2 to the 35mm f/1.5 suddenly makes sense, don't you think ?
FYI, Peter Kitchingman talks about 5537 copies of this lens.
