I have a 650d which came with an 18-55 IS lens, I am looking to buy a telephoto lens. Still a beginner and not sure what is best as there seem to be so many lenses available.
A quick look on Ebay shows
EF -S 55-250 F/4 -5.6 Mk11 £119
EF 75 - 300 F/4 - 5.6 III £109
EF 80 - 200 F/4.5 - 5.6 II
EF 70 - 300 F/4.0 - 5.6 18 USM
Sigma 70 - 300 F/4 - 5.6 DG Macro £93
Can all these lenses be very different? or will they basically do the same job? Are they just cheap lenses that dont compare to a £1000 zoom lens ?
A little confused with all the choice!......
