cjlai: Nice!
yuhi: Not really.
I have 3 main zooms:
17-35mm (ultra-wide to moderate wide)
24-105mm (wide to moderate telephoto)
70-210mm (moderate telephoto to telephoto)
24mm fits right in between 17-35mm.
50mm is a 'normal' and it fits right in between 24-105mm.
135mm is what I prefer in the 70-210mm range for telephoto. Meaning if I was to shoot stage/concerts the 135mm is the right spot.
That is how I came to like the 24-50-135 combo. I never quite liked 28mm - it's not as able to get everything in. The 24mm is as wide as it gets without appearing like a gimmick.
I also didn't like 35mm on FF because it is too uh, boring, but it does have very practical use, and that is why it is the default focal length on point-and-shoots and phones.
When you use the 135mm much, you'll discover at times that something wider is nice too, and that the 85mm is right in between the 50mm and 135mm. It lets you do some of the shots you'd do with the 50mm and 135mm.
The problem with primes is that as a result of using one focal length you might start to be curious about other focal lengths. For example, I loved the 50mm and 135mm, but when I got the 24mm I started to get into shooting a lot more wide and I forgot how to use the 135mm, tending to like the 85mm more. Also, I fell out of love with the 50mm length, starting to like how 35mm feels.
Longitudinal CA is in the out-of-focus areas - reddish in front, green behind. At the point of focus it's purple fringing. However it's easily Photoshopped - Hue/Saturation/Lightness then pick Magenta and knock down the saturation and lightness.
Mikeshashimi: Ah but the 35mm is sharp too!
ahpingko: Hope you get it back soon!
mastering89: Yeah, but that is what some blogs/forums say - could very well be the people who sell the fake alloy ones posting that. I would rather hear it from B+W themselves.
Second 'big fat and kiut' shot is awesome!
fansoption: If you walk around with your 35mm, I wonder if you'll wonder what it's like if the 35mm has macro (like the 30mm macro.) Then you'd know why the 30mm macro exists.
zhan82: The Sony 28-75mm F2.8 SAM is a great lens. Much better optically than the Tamron and Konica Minolta version. However they downgraded the minimum focus distance. Unfortunately it has a SAM motor, which is potong stim on any camera with DMF capability (A100, A700, A850, A900).
