Using a 50mm f1.4 on a 7D will make it an 80mm, BUT how much light do I lose due to the crop factor? Has anyone done this with much success?
Been pondering a change to full frame for a while now, the 6D has whet my appetite, but in order to fund, I'm proposing to sell a fair bit of crop kit, specifically my current 450D and kit 18-55mm lens, my 15-85mm, my 10-22mm and possibly my very underused 70-300 IS - which would net me about £1000-1200, leaving me to find about £450 to buy a 6D body.
I'm left with the 135mm L and 50mm 1.4, but I'm wondering about a wide option, my local camera shop has a second hand 28-135mm for £125, would I be selling myself short and better off with a cheapish wide prime, 28mm 1.8 perhaps ? Looking at my shots in the last year, my 135mm & 50mm have been used most, I'm using my 15-85 and 10-22 mostly at their widest.
I'm keen to slowly build a good lens set, interested in the yet to be released 24-70 f4, plus the 8-15 in due course, I'm not shooting much beyond 135mm as I generally shot portraits, plants and landscape, but my lingering thought right now is just how much gain will I get from the upgrade, specifically in terms of light collecting performance, imagine noise and colour rendition over my 450D
Go on, help me press the button - and no buy a 5DIII pundits thanks ;-)
