1.- Why?
2.- Is the performance of them so different?
3.- Is relevant the mount type?
4.- About the weight, size and built quality
5.- About price
1. Lets me shoot at 1/60 @ ISO 640 on my M8 at night, or indoors, or any bad light situations I might run into. This is super invaluable for shooting people like this. If I was shooting with the 1.5, that's a full stop slower, and I'd be shooting instead at 1/30 and get a lot more blurred pictures. It's the same reason why people will spend 4K+ on a noctilux over a summilux - they want that extra stop.
2. Performance seems to be the same or similar.
3. I do prefer unconverted/native M Lenses to screw mount and adapted lenses. They are easier to code, seem more secure, and I feel like they are built better too. I also hate the push on caps that require the use of the hood to be functional that are included with the LTM voigtlanders.. the pinch caps are much better and I like how I can use the same cap whether or not the hood is mounted or not. The push on cap for my 28mm ultron 1.9 doesn't stay on at all
4. Weight is definitely the larger issue than size - I definitely notice the weight of my m8 with the 1.1. The build quality is unquestionably better on the 1.1, however.. I much prefer the more positive clicks of the aperture dial rather than the smooth dial on the 1.5. Size is large but I can deal with it.. it's not as quite as large as the 75 lux or 90 cron, and it's still small enough to be smaller than most slr lenses.
5. Price is a pretty large difference, but buying new, you have to figure in the cost of the adapter for the 1.5, which is not cheap either. The cost of both the 52 and 58mm uv/ir filters is pretty crazy, though.
To me it's harder to justify the 35 1.2 over the 35 1.4 CV... for sure the 35 performs better, but the 1.4 is SO much smaller, and in this case we're only talking a half-stop difference, so the price, size, and weight is a lot harder to swallow.
The 50, however, is just fast enough to warrant its extra speed, and since I use a 50 more than any other lens, I feel it's my general purpose lens that can tackle any situation, worry free.
