zigi_S: The elephant in the room hasn't been noticed. Namely sensor DR. Why?

"it is a fictional issue. It is an issue for gearhead pixel peepers. It isn't something anyone else notices or even thinks about."

This is entirely wrong Joseph, please stop spreading misinformation in your posts.

The DR issue is very real, and a serious competitive advantage of Sony sensors in particular. There are multiple examples all over DPReview in reviews and sample galleries. We also covered this with Mr Maeda last year:

Scottelly: Interesting that these photos were shot with an Olympus E-M5 Mk II, rather than a Sigma SD1 with the 17-50mm f2.8 OS.

Not really - that was the camera I was traveling with.

Matewka: The portrait of the Ricoh representative, in comparison with portraits of representatives in other CP+ interviews only proves the general DPR's attitude to the company.

I have no words.

Suave: "The elements are held in place initially by friction, inside their TSC trays, before the TSC is heated at the edges and sealed to lock the elements into place. This type of construction replaces the much more involved traditional method where glass elements were held in place by metal bezels screwed tightly into the barrel."

So replacing front or rear element now requires replacent of the entire assembly at god knows how much the cost.

"So replacing front or rear element now requires replacent of the entire assembly at god knows how much the cost"

No - just replacement of the group. I'm not an engineer but to my mind this should simplify repair, as well as reducing the risk of tolerances slipping over time during normal use. But I'm sure there are people out there more qualified to assess this approach to construction.

alcaher: manufactured landscape... nothing nice about it, very robotic-posthuman enviroment. But that is what it is and we use their products.

"robotic-posthuman enviroment"

It's a factory.

Oh give it a rest, for heavens' sake... good grief.

Markol: Great read.
One thing though: the images are tiny and that's because dpr still uses only 50% of modern 16:9 screens.
Come on, 4:3 is long gone, it's 2015 now.

All images can be maximized to 3000px wide by hitting the expand button at the upper right.

Hugo808: Nice pics but all are taken with large and expensive full frame lenses and not the sort of small and light DX lenses that the body was designed for.

It may show off the sensor at its best but nobody buying a D5500 will be getting the same results.

We actually did a bit inventory recently and sent a load of stuff back. Unexpectedly the camera showed up body only. These things happen.

We didn't have a representative DX zoom in the office. Simple as that. We'll be taking a lot more shots on various lenses as we work on the review.

earthbound_ca: Why is it the long grass and rocks have been viewed 956 times (as I write this) and the young lady on the stairs has been viewed almost 2,500 times? People don't like rocks?

That must be it.

Thank you - I think we got the point.

Studor13: These "tests" make me laugh.

Try doing this regularly over an entire European winter nights:
Leave the lenses on a tripod and shoot 1 to 2 hour long exposures. Make sure you have a few days where you are certain to get some serious condensation coming down onto the lenses.

After 3 winters my 14-24 is still going strong without any problems. I also have the 16-35mm f4 but I don't dare risk this lens because I am fairly certain that it would die a very sudden death.

There is far more to a lens than some apparent sharpness in the corners when viewed at 100% on a D810!

And BTW, 1mm is not insignificant on an extreme wide angled lens.

"Try doing this regularly over an entire European winter nights:

We will not be doing that. But your suggestion is noted.

Karl Summers: Aside from sharpness, how do you account for the difference in hue/luminance values in the blue trim around the window?

Assuming I'm looking where you're looking I can't see dignificant difference in the hue/luminance between the shots but I'll let Rishi chip in here, I think.

That's no clearer, sorry. At which widget are you looking, on which page, for which lens, at which aperture, and in which area of the scene?

Snikt228: The image comparison doesn't seem to work. Just says "Please select a camera" on all the images. With no option to select a camera.

Should be fixed now. Apologies. Reload the page and you should see everything.

mosc: Stunning Candor. Stunning.

@ HAR (abbreviating because it's the end of the day). Mr Yamaki is speaking only for Sigma, and the reasons for the lack of profit in cameras for Sigma are unique to that company. I'm sure it's a tough market to make profit in whoever you are, but Sigma specifically were always going to struggle at the volume that they sell, and given the R&D overhead with Foveon.
