Welcome to a world where corporations control us, instead of the state.

mahonj: Surely each focal length would need a different curvature.
hence are we not better sticking with flat sensors for interchangeable lens cameras?

Well I guess that optical engineers could determine what sensor curvature would be compatible with any lens focal length, by finding the optimal curvature for each focal length, then average it.

Anadrol: Canon should add orange and green cartridges... gamut lacks there compared to Epson (overall IQ is much better on Canon though, I own both).

The resolution is much better on the PRO-1000 (the PRO-6000 is just a bigger version) compared to the Epson 4900 (I own both).
Epson prints are much more grainy !

Thank you Tony Wong, indeed yes, oranges and greens are duller on Canon, but blues are better, it's surprising that Canon removed the green cartridge they had on previous models...

By the way, Epson does make the paper more wet that Canon, Epson seem to use more ink, that's especially an issue if you need to print on plain paper, I have seen a review from some printshop, Epson used about 15% more ink than Canon if I remember well.

HeyItsJoel: FU Nikon. Give me my DL18-50 like you promised.

Wow I didn't know this camera thank you ! Well I'd be very interested by such a camera too, a 18-50 lens is fantastic for travelling !

Well reaching a set curvature would be still easier I guess that trying to get a flat image circle, and you have the advantages of better IQ in corners.

It has been said that it would be impossible to make zooms for a curved sensor, but I don't see why it would be harder to reach a standard curve for all lenses and focal lengths, rather than a flat image circle.

All lenses could be made to fit a set curvature.

In reply to:

Moon0326: Who's gonna use 14mm f/1.8? For astro, you can just buy 20mm or 24mm then stitch. Those two focal length with the same F or faster (1.4) absorbs much much more light (at least 3x). I expected 14mm f/1.8 to be cheaper. At this price range, I don't really see a reason to buy one.

"absorbs much much more light (at least 3x)."

How did you make this calculation ?!?!?!
The difference between f1.4 and f1.8 is 2/3 of a stop (0.66), so 66% more light.

3x MORE would be +300% ! So 4X the original EV value.

Calculate here:

On article Sony FE 100-400mm F4.5-5.6 GM sample gallery (101 comments in total)
In reply to:

deep7: Thanks for the gallery. The lens looks pretty good. Is it my imagination, or have Sony worked very hard to make it work better at the long end (a bit like the old Olympus 18-180 and unlike most zooms)?

These samples also show how much cleaner the A9 is than the A7r2. Interesting.

I do wish you people would learn to use the aperture control on your cameras...

If you would mix A9 pictures and A7R2 pictures downsized to 24 MP,
without EXIF you wouldn't be able to tell which is which...

In reply to:

samhain: If the old saying "lenses are the heart of a camera system" is true, then it's pretty easy to see why Nikon is flailing while Sony is creeping into the #2 position.

Nikon makes great bodies, but the only lens from Nikon in the past 10 years that's been even remotely appealing to me is the 58mm, and sadly that one didn't live up to expectations.

I was shocked to see that Nikon does not offer a 16-35 f/2.8 !

In reply to:

john: I found this long ago when testing the NEX-5N burst mode picture ISO noises. The burst pictures are always noisier than the single shot pictures with exactly the same settings. At that time many people did not understand the reason behind it.

Well among other reasons, when electronics heat there is worse S/N ratio.

In reply to:

whyamihere: The first two thoughts that immediately jumped to mind:

1. This is, to me, the more interesting of the two lenses announced today.

2. I can only imagine how much the lens is depending on the camera for image correction. The Sigma and Canon equivalents are big and have huge, bulbous front elements in order to produce the flattest image possible at the wide end. I can't imagine this lens producing the same level of image quality across the frame as its competitors, meaning there will probably be some optical compromise (distortion, vignetting?) that the camera will try to correct. Of course, that's always the price you pay for a more compact lens.

Well it's maybe easier to make a wide angle lens for a mirrorless camera, optical formulas may be intricate for DSLRs.
