Frank C.: can't wait to see Sony kill the resale value of today's uber-expensive 'old school' lenses....and all it took was a lil ol' bending machine and probably some WD-40! LOL Lens manufacturers must have had their "uh ohhh..." moment by now ;_)

Yes, they will. The surface of perfect focus of most lenses (legacy and new) is concave, ie shaped similarly to this curved sensor. Plus incident light at the edge of the curved sensor is closer to 90 degrees.

Jan, have you tried View NX? Like DPP, it is free (for Nikon), but most operations are literally 10x slower. Let us be thankful for small mercies.

h2k: Don't know if it's nice to expose a trivial failure in such a prominent way.

At least DPRs doesn't seem worried that the next test models might arrive with a delay.

One of their problems was that for the full duration of the war they were tinkering with and changing tank models instead of taking the Russian route of building one main tank model for the duration. More tanks were immobilised through breakdowns and lack of spare parts than through battle.

On Leica T (Typ 701) First Impressions Review preview (2300 comments in total)

Confirmation of my opinion that Leica IQ is not the higher quality the price would imply, I checked the Leica 35mm M (full frame) on Photozone. Centre/edge lp/ph at best aperture is 3600/2400, and Canon 135mm f2 on full frame is 3600/3300. I'd rather pay 30% of the Leica price, and get IS thrown in.

NAwlins Contrarian: Somewhere out there a class-action plaintiffs' lawyer is searching for a client on whose behalf he can file a lawsuit claiming he was duped by Leica's [apparently, based on what's reported here] untrue claims of optical correction, thereby being willfully and wantonly lured into buying a mediocre lens for a high price, and of course suffering grievous emotional distress.

Which is, of course, not to deny that it appears that Leica has been busted in making deceptive claims.

I think if you got a mediocre lense, "grievous emotional distress" would be an understatement, more like GBH, grievous bodily harm.

Strange coincidence, just yesterday I was reading about details (and reading the actual court application handed in 3 days ago) of a class action brought by attorneys Zimmerman in the US re the D600. Links are on the Nikonrumours.com site.

On Exposing another side of Sochi article (178 comments in total)

To put the expenditure at Sochi into perspective, the cost of USD 51 billion is equivalent to 50% of the annual govt expenditure of my country, South Africa (population 50 million). Putin and his friends in the construction business have had a field day.

This design shows up the Nikon Df design with it's dials at different heights, faux leatherette moulding on the side of the hump and busy front of hump. Full marks to Fujifilm for it's exquisite design.

undergrounddigga: Funny that, every other company is trying to emulate Oly's design of the OMD .. whilst Oly users wish they had a mirrorless (PEN) camera with the viewfinder in the corner :)
(or perhaps people would want both type of cameras).

I'm not a fuji user, but from a design point I much prefer X100 or X-E than this.
X100 with its dual viewfinder is just stunning, only if they released a 50mm (FF equivalent) F1.4 with speedy autofocus ..

What is this film you speak of?

forpetessake: Just one thing missing -- they need to add a swiveling LCD screen and more convenient buttons. Basically if they take a typical compact camcorder and use the lens, the sensor, and other guts from QX and they will have a winner.

@howardroark: I live in daily hope that some time in the next few years I will spot a positive, constructive and non-sarcastic comment from you.

Stephan K: At the risk of criticising the efforts of my countrymen, just checked the camera sensor ratings on DXOMark, top rated sensor is the Nikon D800 at 96, Leica M Typ 240 is at 84, identical to the lower-end consumer Nikon D5200 at 1/20th of the price. Vanity knows no price. At the price Leica charges, they should be at the top of the list.

@HowardRoark: This comment from the website "Lensrentals" by physician-turned-lens renter Roger Cicala, who rents, maintains and tests an inventory of 50 000 lenses: " DxoMark has nice graphs for each lens that show distortion, vignetting, chromatic aberration, and resolution at various focal lengths and apertures for each lens they test". To whose opinion do I give more weight: your sarcastic one-liner, or Roger's?

Please explain why you think DXO sensor scores are not useful. I may agree with you on the lens scores (one of my posts elsewhere "The DXO lens scores are inaccurate because eg they have one score for sharpness over all focal lengths and all apertures, which is nonsense, rather use sites like photozone and lenstip which have a full breakdown of this metric. In addition, for "best at", they just put the widest aperture"). In addition, your sarcastic tone is unnecessary. You could have said "No, in my opinion the DXO scores are useless, but am willing to explain why, and to debate"

You specifically mention DXO. Care to mention any other sensor rating websites?

I have done a lot of research on the objective performance of lenses (eg Photozone) in my quest to put together a nice set, and my observation is that there is about 90% hype and 10% objective assessment about "premier" brands like Zeiss and Leica. Many of these lenses for instance have fantastic centre sharpness, but poor edge sharpness and poor bokeh, and are often put in the shade by "consumer" lenses like Nikon, Canon and Sigma (eg Leica Summicron-M 35mm f2 (very poor edge resolution, which may be just a technical nit, but should be unacceptable in a stratospherically-priced lens) comppared to Sigma 35mm F1.4, which is superior by almost every measurable indicator). It also astonishes me that Leica and Zeiss can often charge these prices for manual focus, non-VR lenses which in Nikon terms are AI technology from the 80's.

Kevin Casey: I tried to read this article, but the horrific grammer and profound lack of proofreading made it impossible...or maybe it was undermining my GAS denial.

To Kevin and Frank, why run down someone's typos if their first language is not English? (Kevin, your spelling aint so great either). Why not welcome whoever we can. What is indisputable is that he speaks at least 2 languages. How many do you speak?
