FX Fish Eye Lens on DX Format Camera?
I'm looking at getting a Rokinon fish eye for my Nikon D3100. ( http://www.amazon.com/...002LTWDSK/ )
I know it will work but my question is, does it eliminate the fish eye effect, if so what's the effective angle of the dx fish eye on my D3100?
I don't want to lose too much out of the angle, but I can't find a DX fish eye for around $300.
You should read the description again.
"The ROKINON 8mm lens is designed for digital SLR cameras with APS-C image sensors. For these types of cameras, it provides full-frame coverage - which means that pictures will cover the entire frame. It is also compatible with cameras that have a full-frame sensor."
That fishes just fine. IT's also going to be useable in M mode only.
It's an 8mm. Add crop factor and that becomes a 12mm, still super wide for my taste. I think it will still have the fisheye effect.
The simple answer is, no it will not cure the barrel distortion (fish-eye) inherent in the lens. The crop factor of a D3100 and other DSLRs mean the image is taken from the center of the lens' view. To remove the distortion, use Photoshop or DxO or other software. I believe only rectilinear lenses do not have a fish-eye effect in the wide-angle category.
Ah yes the Samyang 8mm, also sold under many other names.
A full manual lens that does F1, 4. Again it is FULL MANUAL LENS! This doesn't only means you have to focus but also have to set aperture using an aperture ring on the lens.
On your body effectively it would be a 12mm, be aware to that this is very wide and has very strong distortions.
Is this a good lens.yes and no. This lens makes great pictures for a cheap price but you have to learn how to handle it. This is not a lens for quick snapshots. You have to really set things up!
Its manual handling also will mean that it really is a lens for shots you have to set up. You simple are not quick enough to make a picture of an event that suddenly happens. Not going to happen!
So think deep about this. Is it a good lens, well read the reviews I say. Does it gets you some interesting pictures? Yes.
It will work fine. There's a price to be paid though- you lose autofocus and auto-metering.
