Tokina 300mm f/2.8 AT-X 300 AF PRO

Review Date: Dec 20, 2008 Recommend? yes | Price paid: Not Indicated | Rating: 10 

Pros: Sharp, good build, good image quality even with kenko pro 300 2.x if stopped down, nice bokeh, AF is fast in case when it does not start hunting
Full AF path takes a lot of time to scan in and out, and a bit loud on my copy which is well used but still works fine and accurate.

A great, nicely priced fast telephoto prime that has everything that a keen amaterur would ever need. It has great detail resolving power, nicely blurred bokeh with thin DOF, nice colours. Can be used with converters I use a 2x on mine - image quality suffers when aperture is fully opened but around F4 (effective F8 - kenko does not report the real aperture on my 20d) it is great - anyway I strongly recommend to use such a combo with a sturdy tripod with remote and MLU otherwise there is a great chance to make the pic unusable thanks to camera shake. This is not a big deal IMHO.

BTW when used itself it is more than usable wide open but sharpens up marginally when stopped down.

There is slight CA but nothing to worry about.

Tokina 11-16mm f/2.8 AT-X 116 PRO DX SD

Review Date: Nov 10, 2008 Recommend? yes | Price paid: Not Indicated | Rating: 10 

Pros: Sharpness, Build Quality, color rendition, great feel and built, nice handling
none so far

A real surprise for me. I have never seen this sharpness from an UWA lens before.

Center sharpness is outstanding even wide open, and stopping down some clicks pulls up the corners to this standard. My opinion is the limiting factor of resolution is the 8 mpix sensor on my 20d. The colors are neutral and nicely saturated. On a good sunny day using a polariser is pure joy.

Build is sturdy, but forget the older tokina's 'all-metal-and-glass' build here. Otherwise the plastic parts are well put together, the lens handling and using feels great, rings are moving smooth but not too easily. AF-MF switch is clever, just pulling back the focus ring makes MF, pushing forth makes AF.

AF is fast, accurate and moderately silent, although not hsm. Not a big deal.

Some other owners complains about CA and some flare, none of these were noticable in my photographing habits not to mention that newer bodies eliminate CA themselves and all raw converter offer nowadays some kind of CA removing methods.

Personally I have never had to use CA removal on my copy was absolutely negligible.

Now I have to learn how to use properly an UWA... Smile

Canon EF-S 55-250mm f/4-5.6 IS

Review Date: Jul 23, 2008 Recommend? yes | Price paid: $230.00 | Rating: 9 

Pros: Price-performance ratio, small, lightweight therefore portable, acceptable image quality, very good price. Good range. Focus is reasonably fast considering the micromotor drive.
All plastic build, including lens mount, front lens filter thread and manual focus ring rotating during focusing.

A good color and contrast with a bit above average resolution in a lightweight, compact and not too expensive package. I got mine used at 115 GPB which is great price for this range and portability.

I have tried 2 examples and was not able to reach the above mentioned 4 stop IS effectivity. Maybe it is somewhere between 1 or 2.5 stops, but as the shutter time goes under the 1/focal lenght rule visible loss of sharpness appears on the pics - maybe I have a bad technique or I am expecting too much from the IS system. In my opinion it helps to avoid blurred images at a price - this price is we are loosing some of the sharpness.

I will practice further because I am going to use this lens as a travel lens together with my 11-16 tokina.

All in all, a good performance for the price paid.
