Notes on Sigma 70-300mm f/4-5.6 DG APO Macro Telephoto ...- I'm really happy with the result I achieved with this lens. Every shot is sharp. The only issue is the macro switch which is difficult to move at times.I tried shooting at f4 and the result is not as sharp but at f8 is where this lens shine. The lens feel is quite acceptable for it's price. I reccomend this lens because of it's value for money and acceptable performance.

Notes on Sigma 70-300mm f/4-5.6 DG APO Macro Telephoto ...- Great lense for the price. Works as advertised and I have no complaints about the sharpness or contrast. The macro works fine but with very limited depth of field.

Notes on Sigma 70-300mm f/4-5.6 DG APO Macro Telephoto ...- This range just does not seem to have a really good lens on the market right now and hopefully one of the companies who makes K mount lenses will do something about the problem. If I had it to do again I would buy a fixed lens at 300 or 400 in a manual focus lens.

Notes on Sigma 70-300mm f/4-5.6 DG APO Macro Telephoto ...- I've owned this lens for about a year and use it on a *istDS. Used in good light, the focusing is quick and accurate. My pictures are sharp wide open or stopped down... doesn't matter. I just returned from a vacation where I took many bird pictures and I can't see how the definition in the feathers could be any better.
No, it isn't an f/2.8 lens, so don't expect miracles in low light. Still, it does an acceptable job here, too. Macro function is good, but the switch can be difficult to move back out of macro mode.
The size and weight are reasonable. It is well worth the weight, space and effort to take on multi day hikes in the deep woods. Been there - happy I had it. Zoom in on the big animals far away or close in on the bugs and flowers.
I'm sure that there are slightly better lenses out there, but not for anywhere near this price. To me, it's easily worth twice what I paid for it. I'm extremely happy to have this lens in my bag! For the function and price, easily 5 stars.

Notes on Sigma 70-300mm f/4-5.6 DG APO Macro Telephoto ...- When I manually focus the lens the picture is of very good quality but the auto focus does not work very well at any distance
