Vignetting did not seem any better or worse wide open and in a few instances I was able to correct for the lens' short comings in Photoshop.<br /><br />Having read a review of the Zeiss Batis 25mm f/2 it seems that even suffers from some fall off and distortion when shot at wider apertures. Probably par for the course given the width and speed of that lens. I'd be curious to see that lens tested alongside the Oly Zukio 21/2 or 21/3.5. <br /><br />I have a feeling that the Batis would win in contrast and certainly flare resistance (flare and ghosting is an issue with the Olys). What I am most interested in is how they stack up in corner performance. The Olys are and have always been amazing in the corners for their focal length. I would think Zeiss could pull that off nowadays without issue, especially considering the lens is the less wide 25mm.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-1709537690528523236.post-40146948093417431372011-10-17T06:50:59.451+10:002011-10-17T06:50:59.451+10:00Charles

I thought I had this figured out as being ...Hmmmm. I thought I had this figured out as being the characteristic of an "inexpensive lens...but then at end you showed the same lens and 35mm film. Now I'm confused.<br /><br />In order to completely illuminate an area a lens must be well designed and produced (expensive) or be for a larger than usual format. My xPan for instance shoots 35mm film but uses medium-format lenses.<br /><br />There must be something about the angle at which light hits the sensor???Charles Maclauchlanhttps://www.blogger.com/profile/16371804975922943864noreply@blogger.com
