if you're doing candids, 50. One sec lemme find something you'll find useful-
I don't know, i only ever tried them in my iPhone. Try googling for answers if the OEM iPhone headset works in Blackberry's, if they do, it's a safe bet the Klipsch's will too.
there's a 50mm canon lens that's roughly the same if that's what you really want
I'd suggest hitting the photo gear thread and asking a bit more in there, I'm not the best at remembering who has all the canon lenses
bopie is one
that's actually my main 50mm, the only issue is that it's pretty zoomed in and I don't know if you're looking to do sky shots or not, but it's a gorgeous portrait lens.
here's an adapter for cheap, only thing is that you have to operate in complete manual (or maybe aperture priority works, I dunno)
ah, right, the whole EU thing. Is there an equivalent service maybe?
craigslist and thrift/pawn shops may yield cheaper results, but then again those are also the sketchiest results, heh.
people seem to enjoy it, though I'd keep an eye on the price, that site shows an average price of $153.04 according to the reviewers, the link you sent me is equiv to $212 or so now
something wide with a nice, open aperture, of course. the 28mm 2.8 I linked has been pretty useful to me so if you can find something similar, you'd be good.
opening a new one will get dust on it too. a quick cleaning takes care of most issues, if it's an interior dust problem taking it to a local camera store for 40 bucks will make it good as new.
I bought a bunch of lenses with a camera that hadn't been used in 20 years, most of the lenses were 30 years or more old and were in faux leather/rubber bags that were deteriorating into ugly, rubbery dust. It was like sticky soot.
only with a LITTLE self cleaning, the 28mm 2.8 from that set has been one of my clearest and sharpest old lenses.
another issue with the whole nikon vs canon thing in lenses is that nikon still uses the same "F-bayonet" mount it did with its first SLRs so something like this fits my D7000 (obviously minus autofocus), but canon kept changing things and you can only buy DSLR-specific EL-mount lenses for canon DSLRs, roping you into staying in the modern market.
such is life buying lenses for a canon DSLR
dig around craigslist or ebay for used ones or something similar, otherwise you're much stuck with $400+ for pretty much anything of value
