I used my homemade adapter. with pentacon 50mm f1.8 len.
I don't have camera yet(too poor). all picture is taken by Canon S3 IS.
The picture is 2816X1584 in reslution and around 2.8 MB each.

This was my initial plan. I tried many ground glass with many different solution. thay just NOT good enough for HD video.
so I come a new plan to make it not show granule(grain) even in 2K resulution.
PS.I will try some HD video cameras.....SONY Z1 & SONY A1P. (they are from school. are they good??)

Looks like you are getting that undesirable circular pattern in your bokeh...a dead giveaway that it's a low quality 35mm adapter. I don't mean to be disrespectful in any way but bokeh is a big deal with these things and when I look at your stills, I find the pattern to be distracting and unnatural. The last thing you want is for your audience to be looking at the very thing you want de-emphasized (the out of focus region). Not sure what the fix for this is because I'm not an engineer but just wanted to give you my opinion for what it's worth.
That may be an artifact from a Cmos, Digital still camera's rolling shutter at high speeds, or its a lens effect. Spinning adapters wont really smear detial in a circular pattern, if it did that would affect the infocus parts too.

I think there really because the cheap len I uesd. It very cheap at about $13 USD. I going to bid another better one....
PS. my adapter is spinning CD one.
PS2. yeah, I bidding a CANON FD ssc 35-70mm f2.8-3.5 WOW!!!
some test say it very very sharp and has very good at colors.
Anyone has any idea about it??

I rethink about what you said. I think you are right about the shutter speeds effect the bokeh. Because those flower pictures were take at 1/20 inside. and the girls picture were take under bright day light at 1/150 ouside.
the 135 len is all at fstop F1.8 . only different is the shutter speed. they looks much different due to that.
Anyone mention this before?? or maybe other people's adapter are able to take good pic at high shutter speed???? please give me some ideas about this. I lost................

What bokeh problems are you guys talking about - in which shots - where?

I think the last two pictures. they were taken under very bright day light. and the len is face to the sun.

WOW, thnak you for this infro.
My adapter works much better. I made the flange depth about 45.5mm for m42 lens. but I don't from what part of the len.
But tonight I made change and meter with where object to len. they are complete wrong.
NOW, they should be right. the picture even easier to get. because I move tooo far between GG and len.
I will update some pic soon.
