Like jugged hare - first catch your hare ... Lenses for curved sensors will be quite plentiful just as soon as curved sensors are mainstream.

Nikonish smartphone?

tkbslc: So it adds a crop factor in order to compensate for the imaging circle being the same size? Interesting.

If they can fit the optics in (presumably by forgoing shift) and the necessary electronics (!) then a focal reduction tilt/rotate for M4/3 or even aps-c for Canon EF lenses should be possible and would be truly interesting.

Indohydra: question...I know this will enrage some architectural professionals...but why not use the capabilities of Adobe Photoshop to correct for tilt ?

It does not say if there will be AF with Canon EF lenses - in fact without electronics it would not be particularly useful. With a little ingenuity the existing Kipon T/S and rotate adapter can be used to mount medium format lenses and thus not need lenses to correct vignetting.

DoubleDash: Step one; buy $4000+ leica m10
Step two; buy $360 glass

On the other hand buy one good camera body that will stay reasonably state of the art for quite a while and you have spare cash to buy more lenses. Keep updating expensive camera bodies regularly and there is "never" enough spare money for lenses (which technically can last "forever"). Trick is to find a brand of camera body that is not updated fairly regularly by "must have" features sometimes held back so that the manufacturer can trickle them out for that very purpose.

GabrielFFontes: Why oh why would they spoil that 50mm 1.1 release with just the Leica mount? It's gotta be a joke. Next up : $500 body kit for Ferrari 458

Just think. Buying a MF lens with the LM mount allows you to decide to change camera bodies for the price of a new adapter. Buying one with a specific other-oem mount means new body/mount (most likely) new lens. No extra costs for RF compatibility - I doubt if any new third party LM lens bothers with RF operting cams any more.

In the end it is not size, nor is it present sales statistics. The dslr will become "unfashionable". Not tomorrow, not the next day. But it will happen quite suddenly when it does.

Meanwhile please keep buying dslr bodies, I would hate to see things change due to fashion rather than capability.

ZeneticX: cool if this sells for $100 or so (I know the original can be found in eBay for even cheaper, but companies gonna earn and this is "probably" higher quality in terms of built)

but not $749

Yes it is "too much" for me as well. But there is such a thing as a premium that some will pay for a rare lens. Think Leica. On the other hand there were literal millions of Helios-44 lenses made. This was and is a quite capable lens but because it is not rare the price is at give-away levels.

Obviously rare and not-rare affect price. And those that try and judge a lens by its street price can be bamboozled by trying to use this as a yard-stick for capability.

If you want a rare Lydith remake then you have your chance right now. If you want a relatively common original Lydith or one of the several very similar lenses made in its day - then go buy one now at a much more affordable price.

If you don't like what a Lydith might do well it might be useful to save "breath" and energy and buy the lens that suits one's purpose.

But to say that you might buy one for "$100" but don't like what it does is a complete contradiction of thought process.

Re-issued for collectors only.

sibuzaru: Overfunded on the first day again, not even Peak Design that is a lot more popular can pull such success, there's something really odd about this company

Meyer were the third largest German lens manufacturer and had a good reputation as lens builders. Somehow the Cold War propaganda meant that their reputation suffered somewhat. At least their lenses were not well known outside the Soviet block. That the later designs did not translate as well via Pentacon's tender hands did not help.

However at least "New Meyer" is not undercutting the street price of the standard "original issue" lenses like Zenit has done for the re-issued Helios 40-2.

If there is anything hysterical on the general tenor of these posts it is the reaction of the unknowing about the unknown. Leica lenses of couse are always "safe". My little (original) Lydith and the several very similar lenses made and sold by other even lesser known German brands is not nearly as bad a lens as popular opinion might have it.

I don't think I will ever be a candidate for VR no matter how good it is and how sophisticated the equipment. I like to be in control of my body and senses and VR promises to bend minds. The better it gets the more the subject (victim) is taken to another place. One can even imagine a VR torture chamber. It seems too "1984" for me.

But of course many like to be taken to another reality in plain old cinema and no doubt VR can eventually take its audience to be right among the mayhem and survive.

Not sure what it might do to more unstable minds.

Interesting camera, but not interesting enough to make me wish to start yet another collection of (SA mount) lenses.

BBQue: Thanks to mobile phones, photography is "almost dead". It would be crazy for anyone, to develop another whole new system. It is crazy enough, that Sony is doing this at this point of time. But thank God they are :)

Camera phone users were never serious camera users anyway.

At best interested in a point'n'shoot compact camera. To suggest that photographers who might otherwise invest in serious camera kit are now merely using their phone is a sort of nonsense. Some might.

But there never was and never will be a large section of the public who will need anything more than the basic photography that the camera phone serves well.

Why digital cameras took off was the "gadget" influence whist digital was still unsophisicated. Now that digital has gone "high end" quality the basic need to "take a pic" can be satisfied by a phone. If the phone does the job then why bother with anything else.

I really don't know what the fuss is all about over the terror of the encroachment of the mobile phone market. It is simply society re-adjusting to the fact that even basic digital cameras are now smarter than most people actually need.

esco: A lot of what will dictate lens sales will also be video. EF isn't going anywhere soon as there are major cinema camera manufacturers who support EF mount NATIVELY as well as their own through first party bayonets, drives, image processing etc. . .RED comes to mind for example.

E-Mount is gaining native support in the video community naturally since Sony has always been a driving force behind video as well so we will see the popularity of Sony continue to rise.

It's not a coincidence that Canon and Sony are at the top now. . they're also key players in the video industry too. These two are able to market their photographic mounts into another industry rather well and provide the most seamless hardware and workflow between the two at least in the segment that remains a notch below the full blown no-limits to cost of using ARRI Cameras, A company which btw is also making accessories for EOS.

Canon and Sony love video - that is where the big margin products are. Only trouble is that it is a small market but it is full of easy-made big money and easy-made money does not care too much if the right tools are expensive.

Try talking to your rank amateur about those sort of prices when the everyman camera also does video at no extra cost.

22codfish: The little yellow Pentax K-01 has developed a growing cult following because of its unique design and excellent image quality reported in the forums. I've been watching for a used one, but they get snatched up pretty quickly. I think Ricoh/Pentax would have a winner if they kept the basic design and colour scheme. and updated/ tweaked the AF, and maybe added a pop-up EVF for sunny days. The pop-up flash is a waste of space.

Shows Pentax "genius". They could have made it a short flange focal distance mount and sold it as a neat package with a designer adapter for PK. Then users could have adapted a range of lenses on to them and "Pentax" could have started making shorter flange focal length lenses.

But of course Pentax had no suitable lenses for such a mount and did not have the wherewithal cash to design and market yet another new mount system.

Instead they probably wasted a huge amount of money by engaging a designer designer to make a wonderfully odd shaped body of little practical use destined to became a showpiece in museums around the world.

dennis tennis: My prediction for Canon is that they have it their migration strategy in place when they announced Dual pixel.

Now, the can provide FF mirrorless with native mirrorless lenses. FF mirrorless with a "smart" but empty adapter to use DSLR lenses. They can provide APS-c mirrorless with native mirrorless lenses. APS mirrorless with a smart but empty adpater with use both FF and APS lenses. Furthermore, they can also provide a Metabones-like focal reducer so that FF DSLR lenes with this focal reducer can be "full used" on APS mirrorless bodies.

I have a Metabones Speed booster for my Sony A6000 and was astonished at the IQ from Canon FF lenses.

Hmm. Focal reduction adapters are all-optical. No need for protocol translation in the unit.

Metabones Smart Adapters and Speed Boosters use the same firmware for their undoubted protocol translation to Sony E/FE and M4/3 mounts. But a focal reduction adapter for EF to EF-M is only a conversion lens insertion away.

Strangely that device is something missing from the EF to EF-M room. A sort of elephant that has not yet entered the scene and would make Canon EF lenses wonder-lenses on EF-M bodies.

But maybe Canon does not wish to make its EF-M series too good lest it become preferrable to EF before they are ready.

Keith Meinhold: I wonder if Sony had not gone full tilt developing their e-mount mirroless systems if this conversation would have taken place at all.

Probably not.

The part of the equation not discussed is the fact that the premium camera/lens buying public is used to paying premium dslr gear prices. This produces very good margins for the guys that sell them. It was probably the reason why Ricoh/Pentax raced for the last fruit on the tree with a FF dslr body of their own.

On the other hand mirrorless has been the new field with the big harvests and competition for market share has kept margins tight to non-existent. This is a place where Canon and Nikon would rather not be. They would prefer to simply keep milking the high margin dslr type for as long as the market is supported.

Their quandry is how to slip into mirrorless and still keep the high margins their company fortunes have been built around.

Noticeably high end mirrorless bodies have been getting more expensive recently. Market share has been found and the market is shrinking - now the product rationalisation begins.

bluevaping: Sony uses piezoelectric actuators for fast focusing E-mount lens, not ring focus motors. That makes a huge difference! Grab mirrorless body with ring focus lens and in few weeks you will discover you want to trade it for DSLR instead or add a key lens with better, accurate, faster focus for the system. I won't even consider looking at decent mirrorless lens with decent stepping motors in them. Just doesn't cut it for 2017. Linear autofocus or bust. Panasonic is upgrading there lineup to linear. Olympus has been using MSC and improved versions for years. Nikon or Canon are just going to sell a secondary body to compliment your DSLR not replace them with the current lens lineup. That works for plenty of people, tho. Just not someone that knows mirrorless with no DSLR glass.

One might wonder why a company might change its camera body type to suit its existing lenses and then change all its existing lenses anyway ....

Presumably much of this can be done by stealth and is why we are seeing MkII and MkIII variants of long term old favourites.
