A case a bang and broken was our original objective. A new was needed, only this should can shoot things well from a greater distance. The household budget was no longer ago than the cost of a Tamron lens. Whether that what is good for this money? It's the Cheapest undefeated in region 70 - 300th So the customer reverences had to serve .... Schönwetter lens to read (s) as to slow Objetiv etc, etc. Despite everything, the price makes the music ... so ordered. A few days later it was there, hurray. But, the thing is herje opposite the old Supersize, logic is supposed to zoom properly ... :). The Objetiv makes a decent impression, ran at our Nikon D40 and behold, awesome. To photograph our dog in the race is now a completely new experience and please me is not now by saying it was too slow for moving objects. Anyone who wants to take pictures of aircraft or Formula One weighing at full speed nor the straight-hitting fly to such Objetive not buy and has no eg Nikon D40 .... We have discovered our camera with this Objetiv new. It's nice people during a call, from a good distance, very close, to photograph undisturbed. It is normal for the "photographers" just right and just plain fun and the way it should be!
