fisheye adapter crashes minilab scanner

[ampguy]

I purchased the Kenko 180 deg .16x fisheye adapter from dazedgonebye (Thanks for the prompt and safe shipping!), and attached it to a 50mm lens on my SLR which has matching 49mm threads.

Shot a quick roll and dropped it off at Longs. Got a call a few hours later that the edges or blackness around each image is freaking out the scanner and is taking the Longs guy several minutes per shot to get scanned correctly.

Interesting, in my inexpensive SLR (Chinon CM-5), I don't see any blackness or the usual circle thing, just the widely distorted rectangle. I can't wait to see the images.

An interesting thing about this adapter is it has it's own set of fstops, so you can adjust your prime lens, or the adapter's lens (recommended in the instructions) to get to a proper exposure.

That's just plain weird.. I can't imagine that you're the only one shooting fish eye..

What these guys really need, is more experience; a couple of rolls shot through these: http://www.cokin.com/cokin-data/composants2/pages-filtres/filtre-397st.html 😀

My own neg scanner is a bit weird like that. It tries to automate the contrast/tones/levels on each scan. So depending on how much bordering there is to an image it can turn out very dull or very bright - even with various blue/green/brown tints. It won't scan 'normal' by default.

If they're using that kind of software they should learn to click the "reset" button to get a proper scan, not an auto-levelled scan.

Least, thats all I can make out from it!

What pvdhaar said. They just need more experience. Actually, they are lucky you shot a whole roll that way. I seldom use the one I have, but when I do, it is usually just one or two frames on a roll.

I picked my negs and cd up yesterday and chatted with the minilab operator about it, he said to his knowledge, there is no setting or automated way to scan these with his setup, he has to manually go through each negative.

I can't understand why I don't see the black part around the image circle on my SLR screen, I just see a warped rectangular image. I thought my SLR was giving me like a 90%+ realistic view of what the film is "seeing" through the lens??

Depending on the focal length of the lens, you may get vignetting. I haven't used mine for a long time so I don't remember where that starts. But I would certainly have thought you would see it in the viewfinder of an SLR. How much are you seeing on the print? I don't think any SLR gives less than 90% viewing area.

I think that dark border is more from lack of light, so when you look through the eyepiece you are seeing the same as on the neg, but you can see it with more light.

If you used a tripod, prolonged exposure, wide open aperture etc, you'll get much less vignetting.

Thats my thoughts, i may be wrong but I used fisheyes for months and thats how I combatted it
