Just got the lens and haven't had the chance to take it outside yet, but here are some test pictures indoors at my desk. Room light with the addition of a desk lamp. Not sure if I'm pixel peeping too much, but initially it seemed like it was front focusing just slightly. I played around with lens micro adjustment and settled on +5. Not sure if it really helped, just seemed a little sharper on the LCD when fully zoomed and seems a little better. I've never micro adjusted any of my lenses and not sure if +/-5 is even noticeable to the human eye. I'll take it outdoors tomorrow and see what happens.

Looks fine, but you really want to do the MAs at the distances at which you are actually going to use the the lens.

that's true, MA should be done between 5 and 10 meters ..

Your 135/2 is within tolerance.

How did you come about this number and is there a general formula based on the lens' focal length?

Thanks for the link. I think I'm going to reset it back to 0 and take some real world shots outside. I don't have 22ft of space to point the camera to my monitor.

Unless I made an error, 50X85mm = about 14 feet.

That would be correct.......if......​. he were testing an 85mm lens.

However, since he's testing a 135mm lens, his approximation of 22 ft. is correct. :)

The test shots look ok to me. What do real-world shots look like?
