I recently had the chance to try out this lens briefly at an event thanks to a photographer who lent me his and here's my thots:
Currently one of Canon's best offerings for the 70-200mm range IMO. For the (relatively affordable for most enthusiasts) price you get an all round superb lens, IQ is top notch even wide open. Lightweight and compact compared to its f2.8 brothers. IS is amazing...can get decently sharp pics even handholding at say 135mm range at 1/30s, if ur handholding technique is good.
Pros:
- Superb IQ, sharp, contrasty with great 'L' colours even wide open through the entire range
- Relatively lightweight and compact compared to the f2.8 versions
- IS is a major plus for this lens....the 3rd gen IS (up to 3 stops correction) is even better than the older f2.8 IS version
Cons:
- f4 (may be too slow for indoor unless u boost up ISO...not a problem for current gen DSLR bodies but maybe for older ones)
- Price might be a bit too steep for most beginners and amateurs, but u get what u pay for
- No tripod collar included, unlike the f2.8 versions (must buy separately - $$$)
Verdict: Highly recommended if u are looking for a good quality lens to cover the 70-200mm telezoom range and have the budget. But do take note that f4 maybe a bit dark for certain indoor scenario so make sure u have a faster lens on hand just in case.
This lens so impressed me that I am contemplating a switch from my current 70-200mm f2.8L (non IS)...the savings in weight and the IS are very tempting factors...but as I do shoot indoor events from time to time I would still need the f2.8 aperture, so still hanging on to my current f2.8. Perhaps I might do so if and when I get a current gen FF body. :think:
