SIGMA 24-135mm Asph. IF REVIEW - PART II
Because of the 10 photo per thread limit, I had to split the review into two parts. This is a continuation of Part I.
(Please go back and see Part One first if you haven't already done so.)
24mm - f4.5 (I know the film name says f4..photobucket cut off the '.5' part)
24mm - f8.0
24mm - f11.0
48mm - f3.5 (Note this was to be 50mm but apparently according to the EXIF, I missed by 2mm)
48mm - f4.5
48mm - f8.0
48mm - f11.0
135mm - f4.5
135mm - f8.0
135mm - f11.0 (I think I might have moved the camera by accident on this one.)
The general trend is that as you stop the lens down, the sharpness goes up quite a bit. Some of you may wonder why the sharpness varied a bit and it was because I didn't have a tripod at the time and set the camera on a textbook. When the lens extended to 135mm, it was so long that the camera tipped over. I had to hold it down on the other end with my hand for the telephoto shots. Despite a 2s Self timer, my hand may have attribuited to the expected blur. Another bit of info is that the AF was a little indecisive or it could have been because of the small changes in camera postion when I changed aperture and focal length. I've hyperlinked the image crop labels so you can view the full resolution images. (Note: all images have thus far come straight from the camera, not modifications made whatsoever.)
Overall I found the lens sharpness fairly good and quite adequate for my use. 24mm at the f2.8 max was a bit soft but judging from the full size photos, I don't think one will notice unless really big prints were made. The AF will hunt a bit but find some distinct lines/edges and its fine. I think this may also be the fact that the Samsung only as 5 AF sensors.
Is this lens worth the price?: Yes (Its a real bargain at $99US)
Would You Buy This Lens Again?: Yes
Thanks for reading and I hope that you all have found this informative or not useful.

Critique and comments anyone? LoL.
Just that I'd love to see some real world shots
At 99 I'd say sure it was a deal but as the suggest retail of what? 399? It
looks to be a pretty poor purchase.
These lenses only cost $99 USD? Or did I misunderstand somewhere?
Well yea. The MSRP at Sigma is $500USD...but if you check out Cameta Camera's ebay store, the lens goes for $99.99US. (buy-It-Now)
So far, I've only seen the Pentax AF mount lens on sale for that price although I've heard that Minolta a-Mount users once enjoyed the same prices.

Thanks for reviewing... Although this Sigma is nothing very special (own one) it is of great use as a general walkaround use (and nice add-on to weather-sealed K10D due to low price and non-availability of sealed lenses yet :-( ). One thing You missed over 10% was weight- this 530 g is something general but with Pentax Kaf-mount it reads as high as 595 g- so heavier of some camera... :-) Anyway it is a nice piece especially considering its low price and possibility of full-frame usage :-) And one the worst side- zoom creep, You know- always streching out (although setting to 24mm helps 90% of cases... why no lock switch (action lens idea by Sigma? :-) ).
Thanks and happy shooting, JR
