Initial impressions and notes
- weight 1.6kg/3.5 lb, quite heavy
- very long lens, about 9.5 inches without hood
- filter size: 72mm
- lens hood reminds me of a toilet plunger
- color and contrast is quite good straight from jpg and K20D
- sharpness is reasonable at f/5.6, I tested few shots in f/4.5, a touch soft but still usable, more use will tell, I have many user errors due to its weight and length
- focusing is on a knob underneath the lens barrel, surprisingly good in focusing
- due to focusing knob location, it is extremely odd if not impossible to shoot portrait orientation, tripod will help
- no aperture f/stop in half stop, even if you turn preset ring into half-stop, the diaphragm release bar will reset it to full stop
- Due to M42 mount in manual diaphragm, blades are closing down in stop-down, I can confirm focus easily in f/4.5, f/5.6, but I can't confirm focus easily on f/8.0 onwards due to dimmer light. A tripod setup may help. Also, the sniper stock gun has a mechanism in cocking the gun wide open for focusing, but I have to choose between gun stock or tripod but not both of them at the same time
- This lens will require genuine m42 adapter with adapter mounted on camera body first, extreme caution is needed as the rear is small and not able to cover the K mount locking pin. All electric contacts are exposed.
- More to come as I put this lens into use

Nice :)
Hey, do you still use the photosniper? I got one and modded it to fit my ef 100-400L. The tair-3 works also good with a m42 to eos af-confirm mount.
