Sigma 100-300mm f/4 EX DG IF APO with 1.4 TC

Pentax and K-Mount Cameras Forum - forums.photographyreview.com
Hi folks...Went out today with my new Sigma 100-300mm f/4 EX DG IF and Sigma 1.4TC...I must say, it is an impressive combo...It is large and heavy, but not like the bigma. The image quality is impressive to say the least...Now today was my first day out with it....

The first samples where all shot at 200 ISO and a distance of appx 120 Yards away...Focal length with TC IS 420MM...All exif in tact...

These next few where taken at ISO 500 and getting pretty dark...My other gear, would be struggling a little bit with the conditions. If you look close, you can see some motion blur that is caused when there is simply not enough light...

These next few I would not have been able to get with my other gear...This beast at F/4 (F/5.6 with TC) is amazing..It focuses really fast...I was using the K10D, not my K20D....These are at ISO 500 and quite dark conditions...With my other lenses, I would have had the ISO at about 1100-1600, but with this large glass, ISO 500 and some EV comp, I was in good shape...
