Class telephoto zoom!

The Pentax SMC DA 50-135mm / F2.8 is the "small" Telezoom the DA * series. It is distinguished by a good light intensity, and the zoom is fully focussed inside - ie the lens is constant in length, regardless of whether the focal length is 50mm or 135mm used. The Focussierring to focus is very easy as with other DA * lenses, and has again a noticeable maximum and minimum stop. The Focussier ring itself can be even with this lens continue to rotate beyond the limit. The zooming ring is compared to the DA * 16-50mm and 60-250mm extremely smoothly. I think the reason is that this lens is traveling at greater distances Brenne tube out, and somehow the air must be transported in or out of the lens. The lens hood also has a cutout for the orientation of a polarizing filter. With good 800g the lens is not one of the lightest. The DA 55-300mm HD is only about 500g and has twice the focal length. But but no continuous high strength List.

Dealing with the DA * 50-135mm is really fun and supplements the DA * 16-50mm perfect. The colors are beautiful sick, and the contours are nice and sharp. Real weaknesses I have not found in my copy. The only thing that is perhaps negative, that the SDM autofocus is perhaps a little slow. I've got very clear Pentax lenses the focussieren faster. The lens is absolutely fail from autofocus. For poorer light conditions, the lens is really first class. I still have not found any problems Focus.

All in all, the DA * 50-135mm a prime lens, because you really can not say anything negative. I love it a lot of fun in connection with the DA * 16-50mm, it is also a great team. But compared to the HD DA 55-300mm is no lightweight.

Conclusion:
The DA * 50-135mm lens is a first class, the Focus is fail, the colors are crisp, the sharpness is great and I. Even light strongly at a consistent intensity Only the weight is perhaps negative to see in this objective.
