Canon EF-S 10-22mm f/3.5-4.5 USM

Review Date: Nov 4, 2004 Recommend? yes | Price paid: $645.00 | Rating: 8 

Pros: 10mm! Lightweight; balances well on the 20D; pincushion & barrel distortions very well controlled; appears to be pretty well constructed; fast & silent; relatively sharp
High perspective distortion; no lens hood; pricy; EF-S mount

I missed my 17mm FOV on my 35mm camera so much when I switched to Digital with the 10D that I went out and get myself a fish-eye lens hoping that it will cover the wide angle - it didn't even come close; so when this lens was announced and was made available - i was the first in line to grab hold of it!

Initial tests show that pincushion & barrel distortions are very well controlled at 10mm; but this lens is highly prone to perspective distortions - objects at the extreme left/right of the frame will appear wider that they actually are. At 10mm, this baby is really wide and if you're not careful, it will take a lot of things into the frame, pretty much like the fish eye but the lines remained straight instead of curved - but it looks kinda weired!.

Sharpness are more than acceptable to me and its no worse no better than my 17-35 f/2.8. When tested with the 17-35 at 17mm f/4, the images taken with the 10-22 appears to be darker than the 17-35 - probably due to light fall-off. However, I noted that this lens has the tendency to over expose (sensor boom?)

My test shots also indicated no visible CA with this lens - but more testing will be needed to confirm this. Overall I am very happy with this purchase; but will have to be extra careful when using this lens to control distortions - keep the camera parallel to the subjects and keep people off the extreme left/right and you should be fine - though I would not recommend to shoot people using this lens at the wide end!


Canon EF 70-200mm f/2.8L IS USM

Review Date: Nov 10, 2003 Recommend? yes | Price paid: $1,500.00 | Rating: 10 

Pros: AF, IS, USM, f/2.8, UD, IF, FT-M, size, weight, length, range, its white! the works! A benchmark on how every Canon "L" series should be.
Buttons are easily shifted while shooting vertically. Gives Error 99 from time to time, draws battery power considerbly, tripod ring cannot be removed without dismounting lens from body.

I've owned the predesesors to this lens, i.e. the 80 - 200 & 70 - 200 and this zoom range has been the most useful for me. Was it worth the upgrade? - definately, the IS alone is worth the upgrade; and at the same time, shorter focusing & better sealing against the elements are thrown in (so does the weight, btw). If I were to sell-off all my other lenses, this one will NOT be on the "for sale" list.

Other than the cons mentioned above, this lens is simply AMAZING!
