430's do not support strobscopic/multi mode if that is of interest to you.

Yeah, it's only a 196MP UltraCamXP... If they don't bring out the MKII soon- I'm selling all my glass and moving to Nikon...
I wish Canon would focus more on the most popular lenses. The 50mm f/1.4 is only OK at best and is REALLY old. This is a bread & butter lens, along with the 85mm f/1.8, and really these should be top priority. A stellar 50mm & 85mm would make someone consider switching brands. Canon does not have great quality in the non L wider angle primes either (20-35mm range). The newly announced primes with IS are too expensive and cheap looking for a non L leaving a void. There is no excuse for not having a stellar non-L prime lineup with 24-35mm, 50mm, and 85mm. Nikon has brought out a new 50mm & 85mm too.
I'll add to Jamesy's test... Here are two 'equivalent' images:Interesting - what made you select 85_F2.5 vs 135_F4 - did you just chimp until the bokeh looked similar or did you bust out the calculator?
#1: 135mm f/4 on a 5D
#2: 85mm f/2.5 still on a 5D, but I cropped the center in post.
The camera-to-subject distance was fixed.
The key thing to note is that the Bokeh appears identical between the two focal lengths.
#3 is the 135mm FF at f/2...
Note that a 135 f2 has far more bokeh than an 85mm f2.5 cropped.
(Unfortunately I didn't do an f2<>f2 comparison, and I ate the tomato)
@neuro: do you know if it's possible to use the FastenR-T1 without putting the Manfrotto RC2 plate? Basically I don't always want my Manfrotto RC2 plate on my camera. But I don't like the original bulging FastenR-3 for storage reason. I do like FastenR-T1 since its D-ring can be flattened.!
I didn't try it, but I would think it would be possible to use the rubber washer from a Fasten-R3 on the FastenR-T1 and tighten it sufficiently like that.
Not sure if you can find them anywhere (I've probably got a couple of them in a drawer), but the older FastenR-2 folded flat:
i often hook on to manfrotto tripod mounting plate too...
Cringe - assuming you mean the little D-ring thumbscrew used to tighten the plate, bad idea. I'd suggest reading this. Then, get yourself a FastenR-T1 instead.
Hence, the lack of posts after people pointing that out.
