Hi all,

I just bought the above lens. Tried shooting with the lens and I realised that the pic seems to be soft at 200mm compared to 135mm, both shot at f2.8. Is this normal?

And there seems to be a 'black dot' or dust inside the lens which I cannot clean it. But when I took a 'blank' picture, I can't find the dot. It is alright? :dunno:

Best that you post some pics. What shutter speed are you using?

Aiyah... I deleted pictures liao....

I was using flash from the SB-600. Max. shutter speed allow was 1/200. I can't set any higher leh. Can't be movement because it was mounted.

Wonder if it is due to movement of the camera? What shutter speed did you use?

It depends, normally, when used wide open, lenses tend to be slightly softer. And a longer focal length can affect pictures evem when mounted. The tripod may not be as stable as you think.

On lenses, it normally does not show up. Users tend to shoot white BG with small apertures to show up dust on the sensor. Not sure if this will affect lens problems.

just wondering what was your ISO. high ISO do soften images a little. at 2.8, focusing is critical for sharpness.

Eh.... the 'dust' is inside the lens, not the sensor. I was shooting with 200mm, f2.8, ISO200 with flash.

Well, I think it may just be the characteristic of the lens. I read somewhere that this lens is soft at 200mm if shoot at f2.8. Will try to shoot and f4. ;p

usually dust within the lens do not cause any visible issues. even new lenses can have some dust within

Had this lense in the past. Yep soft at 2.8, gorgeous at 4-5.6. It's a dumbell of a lens, heavy...
