ok so i picked up my 70-200 f4 L from the post office depot last night and of course first instinct was to fire off a few snaps with it.
(note: for the past few months i've just been using my 50 f1.4 and the low-light performance has spoiled me really)
it was just before dusk (so it was still daylight but was quickly fading) and i was in my garden but i was having to bump it all the way to iso 800/1600 just to even get a 1/100 shutter speed, in some cases it wouldnt even go to that.
now i knew that the f4 is an outdoors/daylight lens when i bought it but surely there are ways of squeezing some use out of it in what was to me still very decent light.
luckily this lens is a sort of stop-gap for me while i check out if the 70-200 range is of any use to me and then i'll sell it and get something else (either 70-200 f2.8 or something completely different), but in the meantime has anyone got any tips for how i can squeeze some decent use out of this lens now. i work all day during the week and it's a shame if i could only use this lens on weekends when the sun is out.
