Anyone own this lens? Seems too cheap to be good but you never know. Add in the crop factor and thats pretty decent.

It's not autofocus, and you have to set the aperture manually on the lens; there's no communication with the camera. So you have to run in manual or shutter-priority mode. That's a hell of a reach though, LOL.

No. The lens won't communicate with the camera, so the only adjusting the camera can do is the shutter speed. The lens stops down when you change the aperture manually, and you need to let the metering system set the appropriate shutter speed.

With fixed f16 at the longest reach, I think that Bulb might be more appropriate than shutter speed priority...

| Looks to me like that thing is more of a toy than anything else - it's probably best suited for use as a telescope rather than a camera lens. |

Not with that knid of reach but I'm inlove with the Sigma 120-300 F2.8
It's so beautifull!!!! And huge! But a zoom with this distance with a constant f2.8.

That IS aperture priority. Shutter priority would allow the camera to change the aperture. |

It'd have to be manual - with no ap reading at all i doubt the internal exposure computer would know what to do. I'll have to go play now and see - when i use an old vivitar lens on my Rebel i just use Manual mode and focus manually and it works. Ap reads '0' in the exif.

No, you have to use Av mode (or Aperture Priority), you change the aperture on the lens and the camera sets the exposure by setting the shutter speed according to how much light gets to the sensor. |
