Yes
currently with my canon equipment i have a tamron 70-300mm lens....

i saw a canon 70-300mm lens 2nd hand for £115 in a shop yesterday, apparently in pristene condition....

would i get any benefit in having the 'canon branded' as opposed to tamron alternative??? i know zoomable lengths will be the same etc- just wondered if it would be worthwhile in purchase the canon branded one and then selling the tamron??

what do you guys think??
 
depending on which 70-300 the canon was, you might well see an improvement, but then I guess it'll cost more than you'll get for your tamron?

I had a Canon 70-300 IS and thought it was a great little lens.
 
Can the 650d do in camera lens correction? This only works with Canon lenses...
 
in camera lens correction (perhipheral illumination correction) is in my 60d and I think it can be used with 3rd party lens. You have to plug it in to a computer and use EOS utility to set up a new lens thats not built in from out the box.
 
Will need to double check aperture specs etc as this would be handy to know...


Ive used all my lens on my 1000d with no issues
Ive only recently purchased the 650d and have only tried the 18-55mm canon and 55-200mm sigma- both of which worked perfectly ok

Re the lens correction..... Ive not had to plug camera into computer to do anything, so i assume it has inside what ever it needs in order to be functonal

What they mean by lens correction is stuff like in camera distortion correction, CA etc... The lens will work (if it's Canon AF fit and suitable for use on a digital camera) but your camera may or may not have built in corrections.

PS. If it's the Canon 70-300mm IS USM you're looking at... I have one and optically it's ok, nothing spectial, just ok. Mechanically it's like a last generation product, the USM doesn't allow full time manual focus, the front of the lens rotates and the IS grumbles and groans but is effective and allows different modes of operation including panning. If it is this lens you're looking at it may be worth thinking about but don't expect it to blow your socks off, IMVHO, it's just a workhorse lens.
 
Cheers for responding....

My understanding and relatively little knowledge compared to most as i can make out lets me think the 650d is only compatible with the ef and efs lens... Not the af lenses - ive seen some adapters on the net £15 -25 that apparently allow the older af lens to attach to the eos bodies. So would i be correct in thinking the correction required would be for the af lens then???
 
Sorry, I wasn't clear, by AF I mean Auto Focus.

Your camera will take Canon EF and EF-S lenses as well as Tamron, Sigma and other lenses made to fit Canon Auto Focus Digital DSLR cameras.

Older third party lenses made for use on Canon 35mm film SLR's may not work fully on your camera which is understandable as digital cameras didn't exist when they were designed. Older Canon EF fit lenses will be ok, but Canon FD lenses wont work. You may be able to use other lenses with an adapter but anything requiring electronic communication between the camera and lens such as auto focus or changing aperture may not work.
