Hey, i am considering getting a new DSLR, currently anything will be a huge improvement since i am running a d 1000 by canon. so i am trying to decide between 3 cameras. 6D Full frame but bloddy expensive 70D Seemes OK but double digit number so its missing something 7D Old So i would like to know your opinnions on these cameras.
6D if you purely shoot landscapes and portraiture, IQ is tops, keep in mind you'll have to also invest in EF lenses if you don't have some already 70D if you want a do it all camera, very nice, live view auto focus is fantastic and flippable touch screen is very nice, basically same AF system as 7D (minus a couple focus modes i think) i wouldn't get 7D now...only reason i'd pick up a 7D over the 70D is if having a metal body is that important to you or you really need 8 fps
well i have been playing arround with the camera, its nice. except for the fact that L lenses are pretty much a necessity for 100% crops, and the ammount of noise EVEN at iso 100 and f22 is kind of alot. then again you will rarely use 20 megapixel images for anything, and anything you CAN use it for (large printouts) the noise will get lost in the printing process. so all in all i think this is the best APS-C camera so far.
congrats, it's an excellent camera and major upgrade over 1000D... why shooting at f22? and noise has nothing to do with lenses... for walk around ef-s 15-85 is nice, should definitely look at sigma 18-35 1.8, short zoom but useful focal length nonetheless, it's prime sharp and you get f1.8 in a zoom
sorry i put noise and lens in same scentence, they were meant to be seperate. small aperture gives better sharpness sigmas have a tendancy to ware out quickly.
Small aperture gives you bigger dof, not sharpness, tho most lenses do perform better stopped down a bit, but by f/22 lenses would be soft because of diffraction Not sure what you meant about sigma lenses, but you really need to check out their recent and upcoming releases
He's probably referring to their kit lenses. We all know kit lenses, non f2.8 lenses are $hit when compared to quality glass. Not all kit lenses are crap but quality images need quality glass. Pay for what you get. Also, it depends on the photographer, obviously.
Apparently a lot of 70D cameras have problems focusing through the viewfinder at F 2.8 or less. In liveview focus works fine.
Aperture has zero effect on noise. too-small an aperture makes images SOFT. Read up on diffraction. Sigmas do not have a "tendency" to wear out quickly any more than Canons or Nikons. Don't spout nonsense you've read on the web.
Smaller aperture does not give better sharpness. Not beyond around f8-f10 anyway. It puts more stuff in focus, which is not the same a the glass being sharp. If anything else, you start seeing artifacts with extremely narrow apertures because of diffraction.
Apparently there is a custom function to fix the back / front focusing issue where you can adjust it per lens.
