debuggerus Online Buy and Sell: On p.1 #1 · Zuikos on Sony DSLR I have just finished converting a zuiko 21mm f3.5 and a 40mm f2 to alpha mount to use with my A900. The process was a lot easier than I anticipated. All took ~2-3 hrs for the conversion. Basically, I just replaced the old mount with a M42 to A mount + a 0.5mm spacer. Infinity adjustment was made thru the side of the zuiko after removing the focusing rubber. The good new is that the process is totally reversible just in case I decide to use them on my canon again. Here are a few photos: 1) 21mm f3.5: sample shot @f8: 2) 40mm f2: sample shot @f2: Nov 06, 2009 at 10:08 PM

pingflood Offline Buy and Sell: On p.1 #2 · Zuikos on Sony DSLR Wonderful! I was just speculating in another thread here about using a similar approach (attaching an M42-Alpha adapter) but thought I would have to dremel part of the original mount off... were you able to just directly attach the adapter after removing the original lens mount? Did you just drill new screw holes in the adapter and spacer to match the existing ones? Was there any gap or anything afterwards? More pics (both of the conversion and with the lenses) would be great! Nov 06, 2009 at 11:13 PM

Tariq Gibran Online Image Upload: Off p.1 #3 · Zuikos on Sony DSLR That's very impressive! I too would love to see more pics such as the rear of the converted OM lenses. Of course, a photographically illustrated step-by-step would be awesome for such a conversion. I sold my OM 24 long ago as I did not think it would be such an easy conversion.

JimU Offline Image Upload: Off p.1 #4 · Zuikos on Sony DSLR interesting. how does that compare to the minolta 20/2.8? Nov 07, 2009 at 02:16 AM

debuggerus Online Buy and Sell: On p.1 #5 · Zuikos on Sony DSLR pingflood/Tarig, I was able to remove the mount and directly put a replacement mount over. It was dead simple. I just needed to pull the internal aperture level using a spring (left over from a rokkor) so the lens can stop down without the need of the original mount (similar to a rokkor 85 f1.7 if you have done one). I used epoxy as I planned to put an M42 mount on them later. Unfortunately I forgot to take photos of the process. The only one I took was of the 40mm f2 with the back mount removed so I would remember how to put them back. That piece in the photo was removed as well before I put the adapter in. I also have a 28mm f3.5. Let me open it and see if it is similar. If it is, I can make some photos. Jim, I've never owned a minolta 20mm f2.8 I have no idea how they compare. I suspect the zuiko has better resolution and color but that's totally speculation. Nov 09, 2009 at 07:19 PM
