In short:
I am very pleased with the lens: excellent optical performance; relatively light and compact; feels quality; Autofocus at Sony A7 OK to Sony A6000 fantastic;
In the article description is a mistake: "The constant maximum aperture of F2.8 ..." The lens has a maximum aperture of F4.
In More Detail:
This paragraph refers to a deleted in the meantime recession. Since the definition for SAL70200G still remains of interest he stops:
The objective to reduce only the light intensity does not make sense. The lens can be for many reasons not compare with the SAL-70200G: The SAL is for A-mount; it is more expensive than 1000; It is brighter, which of course is great, but for heavier and larger (comparison: SAL70200G: 87 x 197 mm, 1340g; SEL70200G: 80x175mm 840g) offer such a lens again for E-mount does not make much sense because you can the SAL70200G with an adapter (LA-EA-X) on all E-mount cameras use. The lack of image stabilization in the camera to complain about is pointless because the lens has an Image Stabilizer, which works very well.
The SEL70200G takes a different approach: Not as bright, but more compact, lighter and cheaper. What you should know but that should not lead to a deduction. With adapter you anyway choosing the E-mount to use both lenses.
The recession of HG war:
It may be that the lens does not focus very quickly on the A7R but it's the camera fault. To point out I find useful, I can not understand to reduce the assessment of the objective reason. I am quite pleased with the focus speed of the Sony A7. On the A6000 really super -> The camera makes it.
The lens has a lens hood, a tripod mount and a lens case is included. The tripod mount can be attached without tools here and contrary to some assertions decrease in the comments: Simply rotate the wheel and pull the wheel. This additional security I think is very useful because so the lens does not drop when it eg carries on a belt and somehow solves the screw.
About the Lens:
+ Looks good (color is a matter of taste), feels at wertig
+ Relatively light and compact for a 70-200mm
+ Optical performance convinced at all focal lengths (please note this end, the numerous reports on the Internet that the SEL70200G certify all good to very good optical performance)
+ Very nice bokeh (blurred area)
+ Beautiful color reproduction, good contrast
+ Protection against splash and dust
+ The focus speed at the Sony A7 is OK
+ Focus range can be switched between "complete" and "infinite-3m". By limiting can be accelerated autofocus
+ Autofocus at the Sony A6000 quickly and accurately. Of course, there are at sequential shots with 11 frames per second committee but the result has convinced me. Have children playing and fast moving dogs photographed with great results. Even birds in flight, you can take pictures with the A6000 and this objective.
Who can afford the luxury of two cameras:
+ At the A7 with full frame great for portraits, etc.
+ At the A6000 great for sports and action; Through the crop factor has an equivalent focal length of 105-300mm with a Super autofocus, continuous shooting speed on the A6000: 11 frames per second with a quite ordinary maximum aperture of F4.
For many applications, the A6000 is the SEL70200G a very interesting combination
o The gray-whitish color is certainly not for everyone
o The light intensity could of course be better but then the lens would again bigger, heavier, more expensive. Here, everyone has to decide for yourself
The only negative thing I can say right now about the lens:
- The surface is very sensitive. I have the lens worn with a belt around the waist where it could easily swing back and forth. By a rivet in the jeans some fine scratches are incurred even though the lens was never pressed firmly
- With landscaped Stativschelle you have to try a bit around the lens in the quiver to get because it is very close. But it is.
Conclusion: For me, the right mix luminous intensity 4, but smaller, lighter, cheaper; great optical properties; Super suitable to the A6000 for Action
