4 Aspherical and 5 SLD glass elements shows that it probably is'nt easy to design such a fast zoom.
Too bad it is not a constant F4, that way the price would have been more in the affordable amateur territory, and smaller size.
Absolutic: Another slow variable aperture lens? Why does it weigh so much? We r talking apertures similar to canons 55-250 is lens which is lighter. X system is supposed to be somewhat a compact system from the get go. Why not have a quality constant f/2.8 tele zoom instead?
Always this fast aperture/bokeh obsession these days, there are lens designs that can stop down further than others without getting huge diffraction but people do not care about that anymore?
The lens is surprisingly small in diameter considering it is a DX sensor, could the relatively high f-stop number for a prime play a part in this?
These IQ tests are mostly for color rendition and quality in general and not for sharpness as ive understood? Because i will not buy the fact that my D3100 beats the Leica M9 in sharpness am i right? Sorry for the offtopic question, i thought it better than to start a thread about it.
Mystery Gardener: 'Photojournalist Ben Lowy explains why he uses an iPhone'
Plain and simple, because someone is paying him to do so. Cheers :-)
Exactly, on top of it all, he does not bring truth out, but instead his view of "art" from the people that suffer, those pictures are a perversion of the truth that actually occurs in our world today.
Isit13: I've understood the maximum speed for a lens is dependent on the rear element diameter vs the sensor distance?
If so, this means you cannot get any magical low size number mounting a version of this with a f/1.2 Noct Nikkor?
I understand that a bigger lens can be widened and therefore let in more light by condensing it, but the rear element has a finite size. But is it really so, that by having let us say the Nikkor 200mm f/2.8, and use this approach in multiple times, you could end up with wide angle f/1 on any mount? Aperture must have its limits, regardless. Because i find it hard to believe that lens makers which have this knowledge would not construct a lens that would let in the light in an unlimited fashion that this adapter does not tell us. No matter how big the first element is, the rear one is limited by F-stop, a mount can only give "so much" f-stop for a given length. I am not sure though?
