Hi guys !
Could you all give me some suggestions ? I like to do DSLR filming and taking quality photos . So I've set my eyes on the Tamron AF 24-70mm f/2.8 SP Di USD VC as it has F2.8 and VC which means a lot to me . But I'm kinda worried as it's mainly for full-frame cameras and so, there will be a crop factor on my Canon 650D which technically means that it will have a focal length equivalent to 38-112mm . Earlier , I saw the Tamron SP AF 17-50mm f/2.8 XR Di-II VC LD Aspherical (IF) Lens which is like one-third the price of the 24-70, But the focal length to me, is kind of limited and I'm not sure if it will produce a substantial amount of quality . Also , I'm afraid that there are compatibility issues or auto-focusing issues for either of the lenses as it will be very annoying to have a slow-focusing lens. So could you please advise me on this and if you have any suggestions of other lenses that fit what I want , feel free to tell me
