On article Nikon D810 firmware C 1.10 now available (62 comments in total)
In reply to:

Vanitas Photo: Canon, Nikon, Olympus... and every other camera manufacturer:

Could you stop punishing your early adopters with half baked cameras and PLEASE deliver quality products from the first day of selling your gear?

Truly yours,
All of us the ef ing customers who buy your gear.

Get real. Today's DSLRs are some of the most complicated elctro-mechanical devices ever made. If they took the time to get every single bug out of the system before launching the product they would be far more expensive and take far longer to develop.
They actually do a pretty good job in my opinion compared with other products out there.

On article Samsung launches enormous 18.4-inch Galaxy View tablet (87 comments in total)

I already carry around a Dell M6700 that weighs over 3kg, this might not be so bad for the increased screen size, though it is a bit overkill . . .

Actually, I have some technical imaging applications that could use all the light they can get at this focal length - I wonder how close it can focus!

I'll just have to limp along with my 135/2 APO Zeiss until I can find one of these on sale . . . ;>).

Is now really a good time for a company to come out with their first full-frame DSLR when likely a mirrorless full frame design would be where camera technology is going in general? Can they make money with a FF DSLR?

Not a Fuji user (please make a full frame system - please!), but I very much admire what they are doing with their lenses and camera bodies.

stevef1961: At 100% those pictures are TERRIBLE. I was considering this lens but if these sample images are legit... either the d810 sux or the lens is sub par. Does anyone agree with me? Soft as heck...

Uh, the wide open shot of the space needle looks pretty darned good to me from edge to edge when I load up the NEF into ACR and apply my standard minimal sharpening. Usually it's the fault of the default jpg settings of the camera or post processing if images posted by DPR are soft - they tend to be conservative in their camera settings and processing.

jhinkey: With these somewhat odd f-stops used in the images I assume a great many of them were shot in P mode? If you are at f/2 or /2.2 why not just use it wide open at f/1.8?

Not really on modern lenses and this is as about a modern of a lens design as you get. f/1.8 to f/2 should not make a difference.

It just highlights that for the vast majority of us photogs that ~90-99% of making a good image is showing up at the right place at the right time. Even my 12 yo daughter has taken some great images because of those two things alone.
Really it's about a dad spending quality time with his young son with some nice images resulting.

Glad to see it here on DPR.

Nice to see Sigma filling in the lens gaps - no longer competing just on price, but they are actually making lenses that SoCaNikon don't make.

Too large and heavy for what I need, but I'm sure this will be very attractive to many other full-frame shooters.

jhinkey: Sony giveth and likely Sony taketh away in some way . . . hopefully the camera doesn't now behave poorly in some other way as a result of using the uncompressed RAW files.

Yeah, likely will not affect 99% of what I shoot, but at least I have a choice if I feel I need the uncompressed file.
So far the biggest issue with my A7RII is getting the colors the way I can with my D800, but it's likely an ACR thing . . .

happypoppeye: Compressed RAW is not RAW. Its compressed.

You are not a newbie here on DPR, you should know better than to make such a statement.

SKPhoto12: Why 3 lenses with such close focal length? I don't understand the brand logic. One step back or two forward will cover that focal length. Why not market one lens with 12mm focal length? Provide all the electronics and I think it would sell better than the almost finished product.

"jhinkey, field of view does not work that way, for same FOV change you need 58mm (34.5 deg.), 100mm (20.4 deg) and 150mm (13.7 deg) That is same 21 deg horizontal FOV change as 10mm (121.9 deg) 12mm (112.6 deg) and 15mm (100.4 deg)a"
Sigh . . . it's RELATIVE field of view change, not absolute . . .whenever someone says "small" or "large" it's a relative term. 5mm relative to 15mm is large, but 5mm relative to 200mm is small.
Yes, FOV does work that way.

In reply to:

mr.izo: only problem with these classical design range finder lenses (beside af obviously), is their short flange distance. this does helps build smaller footprint lenses and all that, but on the other hand shows problems with aberations, corner sharpness etc, which was proved many times using these lenses on mrl ff cameras. yes, they can have super sharp center sharpness, distinctive micro contrast and all that, but for some serious wide angle work (architecture, landscape, interiors..) i would be careful and check things first..
edit:
i forgot: usually, also min. focus distance is bigger on rf lenses, that can be very limited sometimes.

Curved sensors have a long way to go for large imaging chip applications. Likely far more workable for cell phones and such.
The problem is that the curved sensor is likely not all that great for lenses designed assuming a flat sensor . . .

"At wider focal lengths, small differences in focal length make a much bigger difference than at mid or longer focal lengths. So in reality, these three lenses aren't quite "such close focal lengths" as you might think."

No, "small differences in focal length" by definition make small differences in FOV. It's all relative. 5mm change at 15mm is huge compared to 5mm at 50mm or 500mm.
It's the same relative focal length/FOV relation between a 100mm, 120mm, and 150mm - would anyone carry all three of these to get the same relative change in FOV? It's the same discussion, just at different relative focal lengths.

cph71: i look forward to this. never been a fan of adapters, so great that we have more options

"And if aperture information at the minimum is translated to the camera, it may mean that aperture can be electronically opened and closed prior to, and after, exposure.

The biggest problem with mirrorless bodies is that they allow any lens to adapt to them, but with NO native control at all. Buying a Samyang in FE mount rather than F mount is ridiculous because the F mount lens works on conjunction with Nikon's F aperture controls, whereas with FE mount, it is used wide open, or closed, and doesn't support the very basic of automatic operations.

In essence, without proper electronic or mechanica support, you are buying into a dead end."

So much wrong with this statement, but so little time to correct it all . . .
