Fisheye Converters???

Hi all!

New guy here so apologies if this is a silly line of questions (I tried searching and didn't find an answer).

So I've been having a ton of fun with my D5100, went over to B&H today to get a few goodies.

Snagged a Opteka 0.35X fisheye lens, Opteka 0.35x High Definition II Wide Angle Panoramic Macro Fisheye Lens for Digital Cameras , and I was all excited to shoot some bent pictures.

This is what they advertise:

The way the sales person at B&H made it sound was thread this bad boy on and get winners everytime.

All I've managed thus far is shots so blurry you can't discern at all what time I'm taking picture of (I tried it on my 18-55, my 55-200, and my 35mm, going from all the way zoomed in to zoomed out, from one end of focus to the the other, aperture all over this place, and still no joy).

Am I missing something here? or did I just get taken for a ride by a good salesmen?
Is there some setting I'm missing out on perhaps?
Are fish eye converters just not cool with my base lenses? the D5100?

Any insight would be greatly appreciated, no going to lie I was really bummed that i can't get it to work after being in B&H (place is AWESOME)

P.S. Mods sorry if this is in the wrong sub forum.

I'm pretty sure you will never achieve anything like that image with that thing attached to your lens

The image you've posted is probably taken with a fish-eye lens on a full frame camera...

Blurry images mean slow shutter speed or camera movement or both..

I think you would need a shutter speed of 1/400th of a sec or more......

And pan your subject as well...

Likewise, I'd be surprised if that photo above was taken with a screw on F/E lens. But you never know for sure. But screw on F/E lenses and W/A screw ons are a waste of money really.
You are adding even more glass ( substandard ) to a lens that already has a lot of glass , and neither the base lens or the screw on have been properly manufactured as genuine F/E

If you desperately want an F/E lens, the best bang for buck would be the rectilinear ( as opposed to the circular F/E in that photo ) Samyang 8mm. It goes under other names too, but Samyang is probably the best known

Pedroj, I hear ya but that image is right off the manufactures and says taken with the same converter.
I'm not shooting anything in motion, totally still subject, I cant even get it to come clear in the view finder.
I think i'll be taking a trip back to B&H tomorrow to return it. :(

Click to expand...

And they always tell the truth...LOL...If your subject is not moving and you can't get clear images the shutter speed is to slow or you are moving

Just take it back and ask for your money back. I think you were taken for a ride. There is no such thing as a screw-on "High definition" lens. It's just a gimmick that you will never enjoy using.

There is no such things as a free meal when it comes to quality lenses. If you want sharpness, you've got to pay for it.

Good luck getting your money back.

I've played with one but focus needs to be done manually. AND when manually focused for the center you will have blur the further out from the center area. I have fun playing with it but that's exactly it... I'm just playing.
