Hello there,
I just purchased my first camcorder, the DVX 100B.
I ordered a .5x 72mm wide angle lens with my purchase, Digital Optics brand.
It's vignetting, I believe is the term used when the corners are blackened out, in wide in the viewfinder. When I zoom in to get rid of the vignetting, it seems that the wide is no wider than the original lens without the wide angle lens attachment, even less so!
The place I ordered it from is not letting me return the lens!
I'm a new user, and beginning to feel they sold me a lens that doesn't work for my camera.
PLEASE tell me if I am doing something wrong or if this lens just doesn't work on the DVX...it cost $500 and I'd hate to think I'm stuck with something I can't even use.
Purchased the camera to shoot a short film in tight quarters.

THANK YOU!!!:( :( :(
 
Are you attempting to use your wide angle lens with the DVX's lens hood installed on the camera?
 
You'll get that with .5x ....the lens that gives you full range of focus is the .7x wide angle.
 
This may be a silly thought but...is there a clear or UV filter between the lens and the wide angle adapter?

The extra distance could be causing some of the vignetting. If there's no extra filter taking up space...I'd go with the explanation from 330ceo.
 
How far can you zoom out before encounter vignetting?

I agree with 330ceo, if you are not trying to use it with the lens hood installed, then it is likely that the diameter of the wide angle lens is inadequate for a full zoom through range.

Can you find a compromise by using the in camera letterbox to mask off the corners to avoid the vignetting?
 
Thank you Tech Guru-
Though I thought that if I shoot in letterbox mode I had to shoot the entire film in that mode. This is the ope feature I have yet to decide on as for filming with the intent of it being shown at film festivals. The books suggest which aspect ratio mode to shoot in for television viewing but I don't see it mentioning which for film festivals/possible transfer to film, so I was planning on shooting in 4:3. Guess I got the wrong lens!

If the box it came in said Digital Optics, you got the wrong lens no matter what was in the box.

It is conceivable you'd get a better image if you carved an icecube into the proper shape.
 
Well from that comment I guess you don't exactly recommend "Digital Optics" as a brand!:laugh:
 
To be fair, I am only going by the opinions of respected folks here.

A search for that brand name will bring up a lot of negative posts.

It wouldn't surprise me to see a search for "paperweights" bring up the same posts. :)
 
How much vignetting shows up when you capture it into your NLE? Post a sceen grab, I might be able to help you. What is this lens being used for? If the vignetting is minimal on your computer but still noticeable then I think you will be fine if your going to be viewing whatever on the T. V.
 
Yeah, honestly stick to century optics, buy thier ultra fisheye converter MK2 or buy the mk1, mk1 is wider and both would need to be modified to fit your camera but reguardless they are amazing wide angle lenses.

Yeah if you really want good distortion and extreme wideness then the century optics fisheye is the way to go. You can only get the mark II though in 72mm bayonet mount. Century optics never made a mark I for the DVX and there is no way to modify the one for the Vx1000 ( the difference in the size of the bayo's is too big).
 
Digital Optics... That's about a $40 lens - And I'm being generous. You don't want that in front of your baby...
