Focal comparison 16-200mm

[Andy]

Nice comparison how lenses with different focal lengths project the 3d space into an 2d image plane

Or, impact of perspectives.

[Andy]

Correct

I just read Haruo Sato's article about the future of lens design at Nikon and he used the 3d/2d description what lenses actually do.

Thanks for the link.

Sato: 'We created a lens that is extremely capable in regards to creating point images on point, one of the key ideas of the Noct-NIKKOR design.'

Here is shot at medium to long distances with Noct showing this effect. I'm not sure how the new AFS58mm would render this but I think that this effect is what he is referring to?

Sat0's article makes me want to own one of these. I also want to buy a 45 PC an I already got some lenses in the 50/60 domain. I hope I do not end as a collector...

I am extremely sorry that Mr Koichi Ohshita is not developing F-mount lenses any longer because the two that he did develop the 85/1.4D and the 45/2.8P are my favorite ones.

Nice gif, quite a big difference it makes.

Please observe what is shown is actually the influence of perspective, not focal lengths per se.

[Chip Chipowski]

Bjorn, can you explain your comment re perspective?  I thought perspective remained the same when changing focal length. 

[Bjørn Rørslett]

Here the person is depicted at the same size for each focal length. Thus camera has moved and accordingly, perspective is changed.

If the camera standpoint remains unchanged, perspective of course also is constant. However, in that case, detail magnification is proportional to focal length.

Aha - thanks for the explanation!
