I have a Nikon D200 and i want to do 180 and 360 panos. The only lens i have is a 50mm f1.4.

I need to know whether to go for a new fisheye lens like a Sigma (but not sure on focal length needed - would it be 8mm or 15mm?)

Or, should i go for a fish eye attachment to go on the front of my 50mm f1.4 lens?

What are the pros and cons of both methods, and what are my options?

Do you have any examples i could see with similar bits of kit?

Thanks.

Not possible with Panoweaver and 50mm

To use Panoweaver you need to use a fisheye lens like a Nikkor 10.5.  This will requre 6 images around +1 UP zenith and +1 DOWN Nadir image total 8.  OR

Sigma 8mm f/3.5  with a Nikon Mount. 4 images around optional +2 1up/1down

Forget attachments as they are all rubbish and never offer any decent quality.

Nikkor 10.5mm Fisheye

Sigma 8mm Fisheye

Tokina 10-17mm Zoom Fisheye

are all worth your money.

Regards, Smooth

Always the option of a peleng 8mm for the cheapskates, sharp if basic. Look on ebay.

http://timhatch.com/projects/wwp-equipment/
has examples of virtually every equipment combination at their best from the world wide panorama exhibition.

Thanks, not sure if i want to fall into the cheapskate category (!) i'm after something cheap though if the quality is severely sacrificed then i'm willing to spend out a little more.

I was speaking to someone about the two fish eye lenses, Nikkor and Sigma. And they said the Nikkor's quality was so much better. Would it be a waste of time for me to get the Sigma 8mm?

I want sharp pictures really and i want to operate professionally so is there a great difference between the two?

Thanks all of you (again) for the help.

It's all relevant.

The Nikkor 10.5mm is sharper than the Sigma 8mm (by a little) but you shoot 6+TB to cover a sphere. Where as the Sigma 8mm can cover the same in 4 shots with a little clone/patch/heal on the tiny zenith star.

The Peleng is a budget lens that can produce some good results "IF" you get a good one "IF" you can live without camera auto focus and "IF" you shoot to avoid it's sun flare disadvantages.

People who say the Nikkor is "much" sharper are kidding themselves with what is relevant to Internet display. It's better but not HUGE and really for the extra work...... (6+TB vs 4 shots) Make up your own mind!

Owning a Nikon DSLR already the Nikkor 10.5mm could very well be the best solution for you.

Remember this: Just because you see or a pointed to some panorama images shot with a particular camera/lens combination doesn't mean these will be the results for you just because you spend the money buying them! There is way more to it then just dollars. Photography skill, processing skill and optimizing all come into play.

Regards, Smooth

Thanks Smooth

By the way, what does 'TB' stand for?

TB = Top and Bottom Shots. You will also here these called Zenith and Nadir or Ceiling and Floor, Up and Down shots. Easypano choose to call them Top and Bottom.

Agreed.  Sometimes use of terms is confusing.  Write down on piece of paper..

All horizon images = all images taken around the horizon

Zenith image taken at 90 degrees UP from the horizon. 

Nadir image taken at 90 degrees DOWN from the horizon.

Hope this helps
