Correct... the lens does not influence the camera sensor's ability, but the "wrong" lens on the "right" body can easily reduce the available pixels for the sensor.

A 6mp camera with the right lens, can get almost as many pixels as a 21mp camera with the same lens.... in which case the 21mp camera would be a "bad investment" if only used for panos.

("bad investment" is of course to be taken lightly, but still it has merit).

Better read what the experts on the subject say:

For example shooting 4-around with the Sigma 8mm f3.5 FE on a 6MP 1.5x crop DX sensor Nikon body in portarit oreinetation I get a stitched 360x180 of just over 6,000 x 3,000 pixels; yet with the Sigma 8mm f3.5 FE on a 21MP fullframe sensor body Canon 5DMkII you only get a little larger 360x180 pano of 7,000 x3,500 pixels.

Default Lens comparison

Thanks for the replies, this is exactly what I thought: that if wrong lens type would be selected I would get only low resolution images. The forum links you have posted suggest that a 12mm Tokina might be better than a 8 or 10.5mm Sigma fisheye. Which one would you suggest for me with the Nikon D90?

I am absolutely not qualified to suggest anything for you, since I only use Olympus equipment.

If Hans gives his opinion, I would urge you to follow his advice.

Note that those images shows the image circles on a Full Frame sensor, and not on a DX, which I believe your Nikon is? On a DX camera the 8mm will fill much more of the sensor, just like the quoted text says (with that 6Mpx camera).
More mm means more shots and higher resloution.
It's always a compromise.
Like Trausti I'm only using Olympus, and thus we feel safe because all our lens choices are good , while with Nikon and Canon you may end up with something that isn't optimal? Listen to other Nikonians!

Good? You say GOOD?

Have you ever tried a 12-60mm? That is one FANTASTIC lens!

With the E-3 body it is unbelievably good. Fast and clear images.

The kit lenses I got with the E-520 body (14-42mm and 40-150mm) were really good in my opinion, and these are also praised as some of the best kit lenses available from any camera company... but comparing those to the 12-60 .... the only realistic comparison would be something like milk compared to bread.

I was just deliberately trying to be modest, to not upset our friends with Nikon/Canon too much
No, I haven't tried the 12-60. Neither have I used my kit lens, but my 7-14mm is "glued" to my E body !
Not a bad lens that neither

I have never come across 7-14mm, but it is very highly praised EVEN by the NiConians, and what little I have seen shot with it, has been worth quite a few WOW's. It is indeed the next lens I am wishing for, and after that I should be set... except for a Samyang for 4/3 mount. Just for playing with it, and see how well it does. The price is so low that one simply can't be on the losing end by purchasing it.

Still for me to get the 7-14mm... it will require a lot of luck involved, since there is almost nothing "Oly" here in Peru. My E-3 with the 12-60 was a once in a lifetime lucky buy. Brand new camera (517 actuations - in shop)... for only 1230 dollars. Crazily lucky.

For a Nikon APS like the D90 I would buy the Nikkor 10.5.

Stitching 6 around + zenith is always easier than stitching 4 around with a Sigma 8mm.

You will always get good controlpoints with 6 around.
This also means that it is much easier to do automatic template stitching in PTGui Pro
