<p>thanx all of you my friends . i got almost all of my answers . if you take an image with canon 7D and sigma 10-20mm f 4-5.6 at 10mm in f 22 and take another image with canon 5D mkII and canon 16-35 f2.8 L at 16mm and f22 , is this two image has the same distortion and DOF or the distortion of the sigma is lower than FF canon 16-35 and the DOF is higfher ??</p>

<p>thanx for your response , i mean if you take an image with sigma 10-20 on a crop sensore in 10mm and take another image with canon 16-35 on a full frame in 16mm , and compare this two image , the veiw is the same ( 16mm equivalant) but i wanna know which one has more distortion in image and which one has better quality in contrast and sharpness ?</p>

<p>is there any opinion about these two lens and comparsion of them in distorsion of image and image quality ( sigma on a APS-c and canon on a full frame sensores ) ?? cuz these two have equivalant focal lenght on wide angle .</p>

<p>i have a sigma 150mm f2.8 macro for macro shots and i wanna know is there any need or advantage for sigma 180mm f3.5 macro about resolution and sharpness and color contrast for me to go for a change my macro lens ?? </p>

<p>i think the best lens for indoor sport photography is canon EF 135mm f 2 L ...but you must think for the price of that ...</p>

<p>i can say that you can take the same sharpness of L series from canon 100mm f2.8 macro and more better in price from the sigma 105mm f2.8 macro and even more sharper than L series about half price of the prime lens from sigma 150mm f2.8 macro .</p>
