Kit Obj. 18-55 had already shot tens of hours of video and thousands of pictures and was pleased with many. With the 70-300 I am closer not only in the hall handball off and bekomm better Action Images (problem is always in the hall, the light intensity and thus the reduction of the still acceptable exposure time (1/250 usually skyrocket in Action or shorter) with simultaneous the ISOs). Even at ISO 3200 and 1/250 in part I 300 focal length still acceptable Portraibilder in motion I go but before direction 70mm and even if ISO remains at 3200 we see on the screen when viewing still good pictures. The kit Obj 18-55 I had with 55mm and 3200 so the grain was this not nice because I had to part 1/100 down what this degenerate into bad to useless Schlieren images in motion again.
Disadvantage is that no one has beautiful wide angle like the 18-55 which suggests some action scenes but come across better. Tested Maybe times n with Sigma f2.8 or even less with wide angle for the future, I have the Zomm F1.8 and was impressed but unfortunately the focal length somewhat limited, but when the light intensity should be not so much complain)
This lens I have also used nature shots and sharp images get compared to the past. Get closer without having to go, macro at 300mm without a tripod even good pictures (Sony A57 has a built like all Sony Stabilizierer). 300mm recorded beautifully the city and the cathedral, unfortunately a big push in those recordings is very temperature dependent. One sees otherwise excessively deforming the air by the heat of the sun on the roofs. Marriage in the morning or on cooler days with less smog but the lens is recommended for beginners.
Advantages over a 18-250 Always plan objective is that one has built a much finer Focusierung what surprises me a little. This is probably done on purpose because here you have the 70-300 normal range 90 ° rotation in Macro switching (only in the range 200-300) did a 180 ° Focusierungsfreiheit. When I found that you no 18-250 90 ° had thus Währe 70-300 fine adjustable.
Did this not bought here special but the specialist shop with an Action of 50 for old lens (but none have delivered) the price Währe instead of 200 only 150. They had but given me without exchanging lens but 40 discount and for 160 I can not muck definitely , Should even a 70-200 f2.8 be (think before on 1st generation Tamron, they have better optical performance than the sigmal this for but other advantages) then I highly recommend this lens then sell or use as a spare or for certain applications.
