solid device :-)

Makes at first sight a good impression. Macro function not bad at Nikon d90 but of course not the same as a true macro lens. Macro range is likely to be sharper ... for landscapes is the focus really well .... but I am testing on. First pictures have been satisfactory, and think it will be my top Always be objective. I got it only a few days and could not fully test it. What struck me immediately was that the bayonet very hard to "edgy" ran on after repeated and apart from the cam running it better and easier. I am ever stayed by any objective ... is a bit strange.
At first I thought the sun visor can be nciht into place well, is necessary ziemlichem emphatically, but then she snapped audibly and seat bombproof on the lens.
A great pity, I find that the 70-300 Sigma is a quiver here and at a Pbjektiv that significantly more than than twice is so expensive, not even a bag there. Probably comes top on where to buy the lens ... because at andenen providers there is a bag or quiver with them.
Otherwise, the lens makes a good impression processed. Good feel and I think it will serve its purpose as always top lens thoroughly.

Had a quiver here and would run the same bayonet easily and cleanly at the Nikon there is 5 points ... so I forgive only 4 ....
