Optics Theory - This forum is aimed towards the TECHNICAL side of photographic OPTICS THEORY. There will be some overlap by camera/manufacturer, but this forum is for the heavy duty tech discussions. This is NOT the place to discuss a specific lens or lens line, do that in the appropriate forum. This is the forum to discuss optics or lenses in general, to learn about the tech behind the lenses and images. IF you have a question about a specific lens, post it in the forum about that type of camera, NOT HERE.

There is no denying the technological advances going in to lens design these days. Is it necessary for 'world class' photography? I'll leave that for others but the weight reductions in teles is dramatic and welcome. If these things interest you (they don't me) one might try www.lensrentals.com/blog for some great tear-downs. (I'm not a customer or advertiser of their services.)

Is it necessary to ask this question?

Lens makers are responsible for making lenses, not photographs.

They all have that worried "Sakamoto Ryōma look" to their face.

The subdued Canon sensor colour to their portraits does not help in this matter, but only adds extra sombreness.

Fascinating, indeed.

And Canon, Nikon and Pentax continue to improve and extend their lens programmes for their (D)SLRs. Good to see.

With this new design strategy and on parallel the new lenses with diffraction / Fresnel elements (like the latest Nikkor 5.6/500 PF) sports and wildlife photographers even get less weight with their (D)SLR / lens combination than e.g. Sony Alpha users get with their combinations with Sony super telephoto lenses. Interesting times.

Cheers, Jan
