The kit lens will likely be at its total worst wide open (f3.5) and at 18mm, will give a shallow DOF making things look bad (out of focus) and if your still struggling for speed you will have hand shake. You are waiting for the IS to cut in and steady it up too?
An f2.8 lens will give you barely any more 'light' than an f3.5 one - will still leave you with a shallow DOF and wont have IS to help with the hand shakes (ignoring the 28-135 which isnt worth the bother).
If you are REALY struggling for light you have 3 real options.
1 - use a tripod - if the subject isnt moving this is THE best deal. Now you can shoot at f8 and get a sharp pic.
2 - Use a flash. Subject moving? Then you need to add light , onboard flahs at a pinch .. or ..
3 - buy a very fast prime and shoot high ISO. I shoot indoors with a 50/1.8 and ISO 800-1600 with good enough shutter speeds.
Honestly, unless you want VERY thin DOF or a very fast lens the IS kit lens is fine. |
yes, the kit lens is at its worse wide open at 18mm but its no good saying its better at 5.6-8 when that is not practical for me, just like using a tripod or flash isnt either.
you say unless i want a shallow DOF or fast lens the kit lens is fine but my problems with the kit lens were that it was too slow, not sharp, slow and unaccurate AF, rotating front element when using a polarizer

and chromatic aberration.
as for shooting at high iso, i dont know what camera you have but anything past 400 on the 450D is really noisy.
and the best part about getting the 24-70 that i didn't realize at the time is that because of the weight and size of the lens i can properly get my hand around it and rest the body on my arm and dig my elbow in above my pelvis which allows me to take handheld photos down to half a second without blur. on the kit lens because it is so light i get verticle camera shake. see attached pics:
Kit lens, best out of 10, 55MM - 1/2 - F5.6 - ISO400 - IS on
this is obviously far too much camera shake for the photo to be usable
24-70, best out of 10, 45MM - 1/2 - F5.6 - ISO400 - no IS
unlike the kit lens i consider half of them usable.
not only can i take less blurry photos with my 24-70 without IS i also have the option of stopping down twice at 55MM.
you may not understand or agree with my ways of doing things but the 24-70 has made taking pictures aw hole lot easier than before and it is giving me sharper, better quality photos and also more opportunities to get the photos in the first place.
