I have ordered Nikkor 10.5mm fisheye to use it for 360vr but its been 10 weeks and they have no idea when they will deliver the lens,

they told me they got sigma 15mm fish eye lense, I am know nothing about this lense,

Has anyone here used Sigma15mm fisheye lense for 360 VR?

Input will be helpful

I use the Peleng 8mm 3.5 fish eye lens for my aerial virtual tours. It works great for me. Been using it since 2002 with no problems.

Both you guys have cropping dslr's, right? I've been looking at lenses too, been doing vr's with my 17mm, but I'd like a real fisheye, but I'm convinced the 8mm might be too much with my 5d. I'm thinking the Canon 15mm..

Rhett..... I can't fly, but the Profi sure can.

Why do you think the 8mm would be too much for the 5D? If anything the panos would have more of a field of view and overlap to play with when stitching!

well, it might overlap, but I'd think the distortion would be more extreme, and the quality might drop. It certainly would be nice to have 2, or 3 shot pano's, versus my current.. 20 shots!

I take 6 pictures spaced 60 degrees apart. It's a little overkill but it works out just fine. If you are using the 5D for panos the picture will be crystal clear and the distortion is easily handled by PTGui without any problem.

I totally agree with Walter because I do exactly what he does....I would love to have the full frame behind this lens. PTGui Rocks....what a program!

360's

Has anyone tried one of these? It fits onto a Canon G5, whatever that is.

These type of 360 lenses are very fragile and would fall apart on an AP heli.

High Spy, that wudnt work, its quality is the lowest compared to all kinds of 360. Any 360vr that requires less then total 6 shots is a low quality

Just interested, I've never tried one. Thought it might be fun/easy and work well enough for web sites. I might ask if they have one that fits a 5D, if so I will post result.

There are a number of similar items highspy, and I've seen ones that do fit eos bodies. I think it would be useless for fun, or for cheap jobs including shooting rooms in a house. any high quality job deserves better.

i think that cool pix 8400 fisheye produces the same result.

Anyway back to the main topic, so no one here has any expirence with Sigma15mm fisheye?

Didn't mean to distract your thread, We have used the Canon EF 14mm f/2.8 L USM, this was some time ago with film. The results were spectacular. Big bit of glass. The shots were done of a rugby pitch to demonstrate what it would look like if used as a billboard on the flight path to London Heathrow. Sadly though, we handed over the negatives and the prints I kept seem lost.

Yes I would agree, luckily we can rent lens over here. Current list price for the 14mm is GBP 1399.00, we have better things to spend our money on.

I spent last week with Volovisione in Italy, setting up their new helicopter. They have bought the EF24mm f1.4 LUSM as their standard lens for a Canon 5D, previously I would have said this was too wide for everyday work. I've changed my mind the images were superb with little distortion and I now question why we have stayed with our EF28mm f1.8 USM.

The point of telling you this is down to weight not price. The 24mm is 550g, the 14mm is 560g. When we flew the 14mm it was under a Morley F1 and I remember thinking it was lucky we were only taking vertical shots, our mount could not hold the camera and lens horizontally. Now everyone has moved on and we seemingly can play with these heavy loads without worrying about it. A little repositioning to find balance and off we go. The F1 had to work hard to fly the weight, it coped well. Much better than the Concept 30 with a Mamiya 6x7 under it, burned a few engines doing that.

I fly with my 5d, with a 20mm lense, and i love it. I've just got a similar style from mount ( mine from copterfilms) and it required work to balance, but I've got my 5d balanced perfect, just took shifting my batteries way back, moving the tail servo aft, and downlink aft. when I get time, I'm going to rent the 15mm, and possibly the 14mm.

Rhett..... I can't fly, but the Profi sure can.
