In reply to:

dddesign: Contrary to the review, I think the 24-70 lens is a major improvement - and is the reason I will buy this camera. I want a camera for inside work, so a fast lens is important - and so is the ability to fit things into frame when you are working in close quarters. I see little disadvantage of having a reduced telephoto - 70mm instead of 100, say. You can always crop, but you can never put in what a 28mm leaves out.

Tough call. For my DLSR I have a 24-70 f/2.8 and a 24-105 f/4 and there are many times I yearn for extra reach in the 24-70. But having 24mm is a good bonus. I suggest Sony could have gone for a compromise: 24-85 and taken a very small hit on weight.

alcaher: $11.000 for the 400mm ??? and $2.600 for a 80-400???....

It good to know Tamron and Sigma exist !!

It's good to see the weakening of the Yen by 20% in the last year has seen the prices fall. What a joke both Nikon and Canon have become, although the Canon 400 is still about $2K cheaper than the Nikon.

I can presume Nikon will update all their superteles to match the Canon's much lower weight, but be priced even more ridiculously. We knew things were grim when they announced the 800 f/5.6 VR at moronic $18K, making even Canon's rip-off look excellent value.

What a load of horse manure. One of the best value L lenses and capable of excellent IQ.

In reply to:

halfwaythere: At least its APS-C.

The difference in area of a 3:2 sensor and 4:3 sensor that fit in an APS-C (1.5x) image circle is 15mm^2 or about 4%. Similarly a square sensor is about 4% larger again than 4:3 sensor. Either way it's hardly worth quibbling over.

P.S. $479 for the 20-50 kit. Nice price, Samsung!

Who in their right mind would buy Samesung anything over the Fuji. Samesung are still a wannabe camera company that think technological friviolities maketh a great camera.

No one will buy it now.

Too bad the A7R didn't get this AF system, rather than the rubbish they dished out.

Who said anything about the SLT? I was referring simply to the AF sensor module. Yeah I really thought the fixed mirror would fit in an A7R, although why you want to turn a mirrorless camera back into a mirrored camera I don't know.

Well this is a crop sensor and A7R FF, so it would easily fit. The other way around would be difficult.

In reply to:

PiscesNH69: DPReview shows image ratios in A77MKII are 1:1, 4:3, and 16:9 compared to A77/A65's 3:2 and 16:9. Is this accurate?

The camera has a max resolution of 6000 x 4000 which is 3:2, the other ratio are various crop modes.

DFPanno: If Sony intends for this camera is to be considered a true successor to the RX100 it must continue to fit in a man's trouser pocket.

(And by trousers I mean slacks; not wide-boy cargos and the like)

Any improvement that precludes that context pushes it into an entirely different class of camera completely IMO.

Once I need a bag (I don't do the camera on my belt thing thank you very much) there is a lot of competition out there.

Slacks! Would you also like to wear a skivvy, sip lattes, wear a beret, use an iPhone and grow a scruffy beard too?

Might as well go head-to-head with the Nikon V and J series. How about an underwater version of the RX100 II, but with faster lens at the tele end.

Henrik Herranen: Please, DPReview:

Of all web sites YOU should remember that a list that is called "Key Photographic/Video Specifications" but without sensor size is missing, well, for the lack of a better term, one of the MOST key specifications. (This goes just as well for mobile phones, P&S and mirrorless cameras, as DSLRs.)

To continue, the focal length (both real as well as equivalent) for a fixed lens would IMHO also fall under the umbrella of key specifications.

Then again, I've yet to see someone choose an optical system because of the number of lens elements. I don't think that is key to anything.

Sorry Lars the sensor is a Sony 1/3.06" IMX214 unit. Information is widely available. Not that I really care about camera specs on a smartphone.

Indeed the jpg quality is appallingly bad. Worst results I've seen in a very long time including smart phones. Did they accidentally enable a water painting filter!

I'm already waiting for the much improved Nikon AW2 and some extra lenses.

You can get some decent shots of scales with the Canon MP-E 1-5x @ 5x.

Direct link | Posted on Apr 4, 2014 at 00:34 UTC

What's the effective NA of the lens which is what determines resolution? Really massive aberrations around the periphery of the lens. But still a nice idea that will only improve with time

On Up close: The beauty of butterfly wings article (47 comments in total)
In reply to:

peterwr: Little-known fact: the irridescent colours of butterfly wings are produced not by pigments, but by nanometric structures on the scales' surface that reflect different colours of light, much like the microscopic pits on a CD.

God, I love nature.

Not all butterflies have structural colour and indeed most do have pigments. How for those that have special scale structures which are photonic crystals the interplay of light and the scale causes interference effects which can can lead to certain regions of the visible spectrum not being able to propagate through the structure. These colours are reflected, while other colours can pass through the scale. These so-called band gaps are highly directional, so it depends on what angle you view the wing as to what colours are reflected and absorbed. If at a certain direction red and green can pass through the wing, but blue is reflected then you will see a beautiful shimmering blue. However at another angle the blue can pass through and maybe a fraction of the red and green is blocked leading to another colour entirely.

The most famous butterfly for structural colour is the blue morpho of South America.

In reply to:

Scott12345: Using a second lens to capture depth information to map back depth of field and other possibilities.... could be the biggest innovation in cameras since the invention of the CCD.

Doesn't make it it more amazing. We've had twin lens cameras from the likes of Fuji and Panasonic. Now they were after a 3D effect but HTC is using it for a depth map. Once you have a depth map you can do all sorts of cool things. The holy grail is to be able to create a depth map for video applications.

In reply to:

JWest: How come they can cram 2560 x 1440 affordably into a phone, when I can't get my hands on a decent quality monitor any bigger then 1920 x 1080 without spending a small fortune?

Because it would almost impossible to scale this pixel density up to a much larger device and not have huge issues with dead pixels etc. It's like in the early days of digital when Canon released 1Ds, the yields from a FF sensor were dramatically lower than crop sensor with as much as 50% failure rate and hence the high cost.

Now of course you failed to mention we have just seen the release of 4K monitors @ 24" size that are reasonably affordable, but these are still only about 200dpi. 531dpi would be higher than even 8K. We will see this happen but not for many many years at an affordable price point.
