Not bad at all.....
not bad at all indeed what did you do , be very detailed! also details on lens and speed
could this be the same lens!!!!! as the other thread , please post pics and lots of details , thanks
Same exact lens... Grinded the hell out of the mount with dremel.... for 30 bucks I really didn't take too many precautions... Apparently as Kai pointed out the aperture marking being perpendicular to the hotshoe is way off... This thing needed to turn 1/2 turn further.. As such the aperture marking is directly the bottom.
The shot above was 3 seconds at F/11
Here is a pic of the lens
Ouch! for the lens!! I just lost out on a 25mm last night on evilbay. Think it went for $49. I was looking for around $20-30 range. I would have taken it to my trusty machinist to help me cut down the edges. Be glad they did not use stainless steel in those days ;-)
30 bucks... f it
Is that a cropped and doctored image. Hard to believe no vignetting from a 8mm c-mount lens.
P.S. I have never seen a cut-down job with as much 'character' as that.
It's cropped of course... Lol You should see what I can do with a clutch
Out of camera.. only cropped.. You get reasonable 1600x1600 shots.. Which are fine for 5x5 prints... I wouldn't go any higher...
impressive , i do alot of dremel modifications but never a c mount lens , i used a dremel to modify my case with a 90 mm contax g mount len and to make an ebony grip also to remove stubborn lenses from 110 minolta zoom cameras , etc do you have a pic uncropped, im curious how much larger youve made the image circle with the deeper recessing vs the images in the other thread
So how wide does it compare to? Taking the vignetting in account? I have a 12,5 Meopta something, produces almost a full round circle. A rectangular cutout would be like 24mm Iirc. That's why square is a good way to use these lenses.
Cosina, I'll upload some tonight... I set the camera to 6x6 and there wasn't much to crop.. Given the 6x6 is just digital crop anyway... I'll take a full size tonight for comparison..
Laptopprob, I honestly don't know.... Even in what's in view I't still seems wider than my CV 15mm...
This thing is Stupid Wide in the available fov... I was standing across the street was able to get a 30 story building.. Will post tonight
Well done!! I knew you'd get there eventually. The rear end of your lens is... how can I put this gently and diplomatically? Oh, I know: Butt Ugly!! But who cares what it looks like back there; you never see it while it's mounted, and the fantastic image results speaks loudly!
