I Finally Broke Down!

Too much compression to tell if this one exhibits good resolution or not. How about shooting a resolution chart and posting the results?

Just curious, what did you use for your focus screen?
 
THere seems to be some vignetting.
Like KHmuse said, it's tough to judge the quality at that resolution.

Hey Iced - I'd love to check out that adapter sometime if you've ever got the time.
I'm in Austin as well.
 
oh for sure!
Luis, we need to hook up sometime. I'd be more than happy to let you check out the adapter-
I live directly off of Duval and Mopac right next to National Instruments.
hit me on PM and I'll give you more info-
 
khmuse,
thanks for watching. I'll get a less compressed version up soon, but to answer your question, I used an UV filter and grinded one side of the thing for about 1.5 hrs in shifts over several days.
 
Even with the vignetting and grain of some mini35 adapters, they still capture a really cool old timey effect that is very filmic. Look foward to seeing hgher-res.
 
pretty good, you might be able to kill the vignetting by getting a faster lens. Your look is what I get when I use my 28mm 2.8. My 50mm 1.4 shows virtually no vignetting
 
i'm not sure but it looks like theres some sort of circular smudging going on, might be as a result of the grinding...but i noticed it most on the second shot

Get yourself another UV filter, and take it in to a glass supply, and have them sandblast the surface. Just make sure to tell them to "frost" not "etch" the surface. It's been mentioned there is a circular grind showing, get that changed, and you're well on your way.
 
I had a UV filter sand blasted and it showed up too much grain. Etching may work better. The only thing that seemed to work for me was to grind on aluminum oxide and water in a figure 8 while rotating it every15 seconds.

Yes, it all depends what abrasive they use.
There's a serious difference between etching and frosting.

You want "frosted" glass, with a powder abrasive.
