Maybe the results are acceptable if you just use the upper focussing range from let's say 1m to 70cm AND stop down to f:16 AND if you just make small 5x7" prints. However if you focus down to 50cm the sharpness suffers greatly, even if stopped down to f:16. If you take SLIDE with this setup, they are definitely unusuable. Is it possible your friend shot the pics freehanded? If so, there is always a chance that you alter the distance slightly in the time between the focussing process and the shutter release. This could coincidently lead to some acceptable results. I used a tripod in order to check the focus of the SOOKY-setup at the closest distance and the results were clearly out of focus at all f-stops. Since there is only one SOOKY-M (or SOMKY) version, the result HAS to be the same with all modern Elmars (which are all technically identical). My modified SOOK-Y works now for a fixed distance of 43cm (=17"). You focus by approaching the object and fire the shutter as soon as get a complete overlap in the rangefinder patch. It works great and the focus is dead on - even at full aperture :-) Regards, Alex > Hi Alex, > > I know of two other users who just mounted their 50/2.8-M on their > close focusing "eyes" with no problems.
