Sigma 70-200 Problem Update

[whitewolf]

Hi guys

After all those tips, suggestion, help and reviews from all out there, I have finally put it to Practice and believe me have also found out what the problem was.
Firstly, I just had to get out there to practice what was suggested by all of you, but....sadly it still did not work out well. Disappointing....yes:cry: it was after all those time taking down notes and putting it to practice. I was about to put down my equipment for further review of notes and tips from u guys when, I decided to look for some reasons to blame the equipment than to blame myself soooo, took off the CPL (Polarising Filter) and started to give it a good clean up of the lens.
Took a picture and WHAM...:bsmilie:all expectations of the lens good, sharp money well spent was once again true to it's review. Hence I decided to take a few more shots, without the Filter, and every shot was Sharp and Good...surprised indeed:think:
Well anyways, story is getting to long...sorry, I found out that the Polarizing Filter, SteinZeiser, was the Culprit, confirmed that by putting it on and off.
Hence here are the results that I have after using all the tips n suggestions needed for a good shot. Once again Thank You All....

Aiyoo. You never told us you were using a cheap, second-rate, chop-shop con job filter!!!

I guess your lens is still not sharp dude. Why not follow the instructions given in your earlier post and post some results without the filter.

PS: I see that you've shot these at the widest aperture and @ 200mm focal length. Go in manual mode and try to shoot at a shutter speed of 1/focal length as a minimum. At 200mm, a tiny little vibration can cause the image to be out of focus especially when you're using a thin DOF.

Apart from the lousy crappy filter itself: when testing any equipment it's one of the basics to remove any additional gear to avoid side effects. No lens test ever was done using any filter in front.
