Today I had a nice walk through the forest with my Tamron adaptall 105mm 2.5 attached to my E-600. It's my newest lens and the second time I took it out. It was a rainy day, however at the end the sun came through for some fun. All without hood sadly as I have no fitting one for this lens, handheld and mostly around f/5.6 if I remember correctly.

#3 Wide open, with some processing (contrast boost, adjustment of brightness) as it had some veil flare

It is attached to the camera using a 4/3 - m42 adapter and an adaptall-2 to Pentacon electric m42 mount. Sadly the electric m42 mount is next to useless on other adaptall-2 lenses as the A-M switch on it does not lock in any way, making its use on adapters without flange questionable. Luckily the lens has an own A-M switch Smile .

The lens itself has a small scuffmark in the middle of the front element and is a bit loose. It looks well used and emits a very '70s vibe Wink , with the orange lettering. However it is still a nice lens even though it glows a bit wide open, it sharpens up nicely at f/4.
I havent been able to test performance stopped down very well, as the light is not very well this season and anything over f/5.6 is not very usable right now. Especially as on 4/3 it is a equivalent to 210mm tele, making it a tad long for walk around (although i have used a 200mm Zuiko as walkaround too Twisted Evil , so I guess I am slightly tele-minded)
Sadly i do not have a matching or fitting hood or front cap Crying or Very sad .

Some tech specs:
- It has a six bladed aperture, from f/2.5 to f/22.
- Focusses to 1.3m.
- It has a dedicated A-M switch.
- It is BBAR multicoated.

Picture of the lens itself:


Notice all the colored reflections, I havent really seen this wildly colored reflections in my other lenses. You can see green, gold, purple and deep red.

Thanks, the mushrooms are a my own favorite as well.
It is capable of some interesting bokeh indeed,
usually it is rather smooth, even stopped down, but give it some backlight and a forest full of waterdroplets and everything becomes almost psychedelic Laughing .
