Hi,

excuese me, but the picture quality of the Sony FE 70-200mm F/4 is much better as the quality and sharpness of your image. Your image dont really show the possibilitys of the excellent lens.

The FE 70-200mm F/4 lens is razor-scharp on f/4. I can not tell you why your picture isnt perfect sharp. Maybe sou should improve your photographic skills a bit. There are a lot possibilitys to get an unsharp picture. For bird photography you should use a tripod with a gimble. Your camera and the lens should be as stable es it is possible. You should optimize the af settings of your cam. And the exposure time should be as short as it can. Set a bit higher ISO levels to shorten the exposure time. Depend from your camera (fullframe or crop) it is possible to use ISO 400-800 wihout noise. Your A6000 has a crop-sensor. It means that your effective focal length on 200mm 200x1,6 (crop-faktor) conforms to 320mm lens at a full-frame camera. It is not easy to shoot freehand free a sharp image at this focal length. And sorry for my language skills, i am not a native speaker.

Camera was set at 1/640

The exposure time was ok. Shorter is better.

With that lens you can use F/4. It is razor-sharp.

ISO100

With ISO 200 or 400 you get faster shutter-speed. it is absolutely necessary if you shoot freehand free.

Hand Held

Tripod and a Gimble ar the better solution to photograph birds.

L:24M image size aspect ratio 3.2, Fine quality record F440x1080 12M,

Why??? Use the full and best possible resolution of your camera.

continous shoot mode, continous auto focus, centre metering.

For Birds in flight the settings are ok. But If they are sitting it is better to use single shutter mode and AF-S.

This attached photo is full size, the first one was cropped.

As i said, use the full possible resolution on your cam and crop the images on your pc.

And you are a bit far away from the bird. Nature-Photograper using 400mm, 500mm and 600mm lenses to get closer. But it is really expensive and heavy. To get closer to the birds use camouflage suits or tents.

I thought I had camera set for best resolution, how do you use crop sensor on camera?

Many thanks Ian

The highest Resolution of your Cam are 24,3 Mpix (6000 x 4000px). And the sensor of your camera is allready cropped. It means the sensor in your camera is 1,6x smaller than a fullframe-sensor.

"I thought I had camera set for best resolution"

use the 24mpix mode and maximum L: 6000x4000px quality.

Another example uncropped taken 1/800 F7.1 iSO 800 L 6000x4000 Fine, I think it is a focus problem

Why f/7??? Please use the 200mm Lens with f/4.
And you are still to far away from the bird. It is not a focus problem.
Is there a Zoo in your city? Go to the Zoo and test the Lens on objects they are closer to you. It is not possible to make a picture with 200mm focal lenght and 100m distance, crop over 90% of the image and get an sharp result.
You should go closer as possible.

Thanks, my expectations for the lens are too high, I have had it for nearly 2 years and get good results from closer. I should perhaps have bought a different camera but have spent a lot of money on this system and will have to make do unless there are any longer lenses I could fit on the a6000.

It is posible to conect othe rlenses to the sony system. There is an adapter from commlite E-Mount to EF for 50$.

With the adapte rit is possible to use the Tamron or Sigma 150-600mm on your cam. But a tripod an a gimble are absolutely neccesary. The lenses are big guys and they are heavy. As i know there are no other lenses from Sony with higher focal length.
