Benarm: wow, the RX100 MKII is doing pretty well in low light ISO!

There isn't really anything surprising in the new tests. The FF is a clear winner, followed by NEX, followed by GX, followed by RX -- as you would expect the sensor size matters most. That is, if you are shooting raw. In jpeg, they all have different noise reduction, none is flawless.

ayhani: Technicaly very good but I need blue watch.

How about including enlarged high resolution prints of some old elements?

Timmbits: I would love to see the GX7 compared to the GX1.
does a "10% improvement" really show?
I'd be very interested to see if the claims of their sales department are real.

The old GX1 is of no interest to anybody, it's not a viable alternative to any recent offerings, why wasting time on measuring the old discarded stuff.

OneGuy: Definitely need a curving 3D solid-color car/barrel/sphere. As the color shifts with reflection angles, different cams react differently to it -- with ugly artifacts in the worst cases. Yes, the blue VW was always my first go-to on your original scene because I like to shoot cars. [Ok, a bald-headed guy will not do.]

Secondly and finally, do something dynamic. I'd put a spinning black-white swirl wheel rotating at fixed rpm to get a feel for capture speed.

Wish you the best in making everyone happy.

They need to use a LED timer to capture exposure time as they use in DXO measurements.

Excellent changes!
One thing though still missing. It's not really interesting comparing cameras on the basis of the same ISO, it's the exposure that matters. At least you could have shown the exposure parameters in "Camera settings" pop-up, or better to have a full exif displayed.

'you can [find people on Instagram] who aren’t professional photographers, but they do the most amazing work. If they can do it, how a professional doesn’t do it is beyond me.'

Why would that be surprising to anybody? It's been always the case that people do much better work as their hobby than as their professionl. One thing is to be compelled from within, the other thing is to be compelled from outside by the desire to make money. Professionals need to learn to do only one thing well -- making maximum amount of money with minimal efforts. All the greatest artists were not the greatest businessmen.

On Studio comparison widget article (13 comments in total)
In reply to:

Eliaz: The tool is excellent. However, there is a problem with focusing issue. I am afraid you don't pay enough attention to where you focus upon with each camera, so each camera in a certain comparison may be focusing upon a different item, so when you are comparing two identical spots of two different cameras, one may look blurry (out of focus) and the other sharp, giving the false idea that the focused one is better. I suggest that you lock the focus upon the same item in every shot you take in the studio, rather than letting the camera autofocus.

I don't think it's true. The focusing is always on the central target and I believe it's always a manual focus. It's different FL and DOF what makes different portions in or out of focus. It's a 3D scene after all. Maybe they should shoot a hi-res poster instead.

Comparison should be done on the same exposure basis, not on the same ISO basis. The latter is pretty much meaningless and varies greatly from model to model.
Having bought Fuji X-E1 and Sony NEX5N I see that the Fuji would often select twice higher ISO for the same exposure, so comparing at the same ISO would be misleading, while comparing on the same exposure basis one can notice they have pretty much the same amount of visible noise.
Two more observations. There is not much meaning comparing images on different scale or different aspect ratios unless they can be scaled to match. So the comparison tool needs a scaling option for images with different number of pixels. And also it needs an option to select how different aspect ratios should be cropped. For example, it makes no sense to always match 4:3 image at height, when one uses camera mostly in landscape mode.

madeinlisboa: Why??? Who needs that?

ok. we have a 18-200 and a 18-105. what marvelous innovation can we produce? yes! a in between 18-140!

give me a break! learn with sigma.

@madeinlisboa "ok. we have a 18-200 and a 18-105"

Both of which are cr@ppy, especially the 18-200. If 18-140 turns out to be in the same category then it will be a flop, but if they did improve image quality then the existence of all other 18-xxx is irrelevant.

On Sigma 17-70mm f/2.8-4 DC Macro OS HSM | C review preview (93 comments in total)

I tested that lens, it's rather mediocre performer. Resolution is poor on both ends. True, it does get much better closed one stop, but who needs a big and heavy f/4-5.6 lens. There is also some glow and loss of contrast in high contrast transitions, pretty unpleasant to look at. Color-wise it's probably neutral, but still somehow images look drab. The images don't really look any better than from cheap kit zooms. And somebody needs to check its T-stop, it probably loses an extra 1/2 stop at f/4.

forpetessake: That's been mentioned many times on the forums that the only game left to increase IQ is increasing sensor size, and given time, the FF prices will go down and virtually all compact cameras will be FF.
For some reason this simple fact provokes knee jerk reaction from people with small sensors. Must be a Napoleon complex.

@sfphotoarts: "compact cameras wont all go FF because it dramatically increases the cost of lenses"
Talk about "don't get the issue properly." The fact is, it's just the opposite. The equivalent FF lenses are cheaper and easier to manufacture to the same standards. Check how much Panasonic 12-35/2.8 cost and how much an FF equivalent 24-70/5.6 would have cost? Nobody, of course, manufacturing such FF lens, because it's of little interest to anybody using FF cameras, but maybe one day for a cheap FF compacts they will manufacture it and sell for some $100.

In reply to:

aris14: We need cheaper equipment of top quality.
That said IMO right now is the 4/3 format that allows us to have top IQ and glasses with reasonable cost. I think that current technology suggests that today we can have at least equal with top 24 x 36 mm sensors a couple of years ago.
The 24 x 36 sensors may remain for special projects and demands along with larger ones.
In less than 5-6 years a sensor of let's say 12 x 18 should deliver the same IQ in every aspect with today's top guns...
The rest is marketing...

You don't seem to understand the laws of physics involved. The current m4/3 sensors won't deliver the same SNR as the current FF sensors no matter how many years you're going to wait. With current QE there is little room for improvement left. SNR is lens limited, and since there are practical limits on lens construction the only way of increasing IQ is transitioning to larger sensors. Here is a simple math for equivalent systems: it's easy to make a good quality FF 50mm f/1.4, it's hard to make APS-C 35mm f/1.0, it's probably impossible to make m4/3 25mm f/0.7, it's definitely impossible to make a compact P&S with 10mm f/0.28. And that's only one factor - noise, but there is also resolution, manufacturing tolerances, cost of production, etc. -- all that in favor of larger sensors.

Simon Says: Anyone who follows the tech industry knows that history suggests that any sort of "medium", be it floppy in the very distance past, discs, CF/SD, etc. shrinks over time, while the performance of next generation but smaller medium initially doesn't perform as well, will catch up and surpass the standard of yesteryears.
(For details on this subject: check out "innovator's dilemma")

Sensor is just another example of a medium for light, and there is no exception.

We are already experiencing this trend from Medium format -> FF -> APS-C -> 3/4 -> ?

Trust me, at some point smaller sensors will be technologically advanced enough to be just as good as bigger ones of the past.

Tell it to people, who build telescopes. They must be all fools and don't understand how technology works, because they are building bigger and bigger telescopes.

On 5 Reasons why I haven't used my DSLR for months article (592 comments in total)

The problem, of course, is high ISO performance. Quantum mechanics put a hard limit on how small a lens (or mirror) diameter can be to get a desired SNR. So even if a camera can be made tiny, the lens cannot. That's why those who build telescopes don't dream of making them pocketable one day.

So, the maximizers become gear reviewers, wasting their time testing every gear under the sun; and satisficers become fanboys, spending all their time converting the infidels, who don't believe in one true camera. Neither is an attractive place to be.
Don't try to guess correctly based on the reviews, that never happens. Rather do the following:
- select a few candidates based on your budget and technical data (doesn't take much time);
- order them all from a place like B&H with inexpensive easy returns;
- test drive them all for a week;
- keep the files from all of them as a reminder;
- return all but one that you like most.
That will settle all your concerns, because you will know (rather than guess) that you've chosen what best suits YOUR preferences, and there is no greener grass anywhere. Ignore the reviewers, ignore the fanboys from now on. Repeat the procedure in one-two years depending on your budget and technological progress. If that doesn't help, consult your physician.

Are you saving money so that when you pass away, your wife's new husband enjoys it ?

I am going to enjoy my life. I am going to buy whatever I can afford , not more.

I love waiting for that recently announced camera, I love reading rumors, sheesh I even sit down and design on paper what would be the perfect camera for me.

The main problem for me? is what equipment to take oin a photo shoot !!! I love it. yep, I am guilty.

Life sucks ... and then you die.
