Hard to believe it was raining and 40 degrees F on 12/27 here (very unseasonably warm) and for the last day-and-a-half it's been about 8 degrees!

OK! Here's mine then:
These are all produced with the Knoica Minolta GT lens. I believe it's an achromat consisting of 16 elements in 13 groups, including two AD (anomalous dispersion) glass elements and two aspheric surfaces. It might actually classify as an Apochromatic design but I don't know the materials used (kind of glass) for the two AD elements so I guess I better not jump. It's 7.2mm ~ 50.8mm (f/2.3 ~ f3.2) which on a 2/3" sensor is the 35mm equivalent of 28mm ~ 200mm. It has a macro switch that can be positioned when at either end of it's focal length so there' a 160 ~ 200 zoomable macro at the top end and a fixed 28mm macro at the bottom end.

It's probably not important to this discussion but since the lens is not user replaceable it might be interesting to note that the auto-focus system is a "Video AF system," which uses phase-detection focusing technology rather than the much more common contrast-detection. This makes focus tracking with the system very very nice and speeds up AF in general. With this system the camera not only determines whether or not the lens is in focus, but also how far out of focus it is, and in which direction (near or far).

Subject Distances as specified (below) are measured from the sensor surface plane.

Act cleaned up.

I believe you can only get this lens by purchasing one of the cameras (DiMAGE 7D, A1, A2, and A200) built around it by the now defunct (out of the camera business) Minolta or Konica/Minolta companies. I think the A200 is still selling for about $450 (new) and all the others should be obtainable for under $200.

The point of the thread is to let everyone know where it came from...not to force them to guess.

I thought it was also to show what a lens does bokeh wise, not what the computer can do bokeh wise.

I misunderstood the intent of the thread originally also ... I posted several 'motion blur' pics ...

... before I realized it was intended to be more of a 'bokeh' evaluation thread.

The poster will probably adapt accordingly ... as others have.

Lol, what's going on here.... Don't people read all 100 pages before posting?!

Heh. Yeah, or implode; I have decided not to become upset until the World Soccer Championships.

If possible. Sometimes we have to show off, it's part of being photographer I guess. There is a tendency, since long, to show spectacular images rather than clinical boring describing evaluative images. I try to act as a model...

Bifurcator, you're welcome. Our friends are thinking of my wish as expressed for example here.

Rustibug, that's a cute little image.

Leica Summicron-C 40/2 @ f/2 on M8

This lens is a bit wierd since the bokeh gets harsher at closer distances. The opposite is the most common.

Ah, you never know with relative distances... "gets harsher"? Hmm, well, everyting isn't admirable.
I have a, to me new, Olympus Pen FT 42/1.2 sent for service and I'm looking forward to see how it renders OOF areas. I suspect it can look like your compact Summicron sometimes. It's very fun to play with these small old lenses!

Oh, OK. So only real lenses and they should be named. OK, I'll straighten up my act.

I hope his head will be OK. That sounds painful!

I straightened up my post above and added some information about the lens. Here's another shot with the same lens this time a distance shot taken about 4 to 5 meters from the focus point (subject).

Embarrassingly honest. Is that even allowed here? I like it!

Bifurcator, you're welcome. Our friends are thinking of my wish as expressed for example here.

Ah, way back on page 25.

Yeah, sorry, I took all my direction from the initial post. Hehehe,

It looks like I clobbered every one of your suggested revisions. Sorry about that. Oh well, it's all good... (I hope).
