Here are some more shots taken with the Optomax 200mm F/3.5 that I reviewed here
Because I was impressed by the overall performance of it's smaller brother I decided to try out the Tokina SZ-X SD 28-105mm F/4-5.3 to see if it could deliver a similar performance over a more versatile focal range (albeit with slightly slower maximum apertures)
Build quality and finish:
A similar story to the 28-70mm, this lens has a lot of metal and an overall solid feel. This lens is a push/pull design as opposed to the traditional 2 touch design of the smaller 28-70mm but otherwise has a very similar finish.
And once again a similar story, very similar!. Wide open we have decent central resolution at the wide end and decent resolution across the frame at the long end. Stopped down to F8 produces razor sharp results ideal for landscapes. Because of the relatively slow maximum apertures bokeh is not a consideration all too often but when coaxed into producing it the lens shows a relatively smooth performance for an older zoom lens, one benefit of the slow apertures is that axial chromatic aberrations (sometimes referred to as bokeh CA) is extremely well controlled. That just leaves colour and contrast, both excellent across the aperture range!
By clicking on these images you can go to flickr where a larger version is available:
It has to be another recommendation, apart from low light work where the slow maximum apertures would be a disadvantage this is a great all rounder and puts in a decent optical performance, best of all people are practically giving them away, go and buy one!
