alcaher: What prosummer means ?

As the name implies (when spelled correctly), it's somewhere in between the professional and consumer categories. Perhaps the same as 'semi-pro' or 'enthusiast'? The usefulness of these categories is debatable.

Joe Ogiba: Does the 80D shoot 4K UHD and have an EVF to see what you are shooting ?

Since the 80D has Dual Pixel AF, the DSLR/mirrorless distinction is irrelevant for live view and video shooting, because a DSLR practically is a mirrorless camera when the mirror is up.
Unless you absolutely need to have your eye to the viewfinder when shooting video, in which case the 80D definitely is not a mirrorless camera.

On article Epson's 4K home projectors to go on sale next month (59 comments in total)
In reply to:

ovatab: What's next? Review of a TV or vacuum cleaner announcement? :(

If you're questioning the relevance of news about projectors, then they are just as interesting to many photographers as printers are. They're part of the wider photography-related ecosystem that also includes cameras, lenses, software and other accessories.

In reply to:

Peiasdf: Fuji's lack of innovation is really showing. Same old sensor and SoC with poor AF. Cheating on ISO number to cover up the age of the sensor. Rely on film simulation and B&W because X-tran's RAW processing issue.

It's not cheating. The camera ISO settings refer to the output brightness of JPEG files, not to the so called "measured ISO" based on sensor saturation reported by DxOMark. The ISO standard allows for different ways of mapping sensor saturation to output brightness.

PanchoVilla: Poor Canon and Nikon, they're battling it out for scraps while Sony takes the bulk of the market. It's sad seeing these once great companies slowly go down the path of extinction!

Color discrimination may vary between sensors because of differences in the color filter array, and there may also be some processing already baked into the raw files. Therefore, raw files from some cameras are easier to process to your liking than others.

PanchoVilla, stating that Sony has the bulk of the market is simply wrong, no matter how much you go on about Canon fanboys and zealots. Sony recently published that they hold 12% of the ILC (DSLR + mirrorless) market. In other words, they haven't really increased their total share since they started making DSLRs a decade ago. They have just replaced their DSLRs with mirrorless cameras.

Meanwhile, Canon has >40% and Nikon >30%, together sharing about 75% of the ILC market, and if we restrict ourselves to professional sports and photojournalism, then Sony has practically no presence in that market at all. But of course, you already know this, which is why you posted your comment in the first place.

steelhead3: I don't understand the battery life difference, especially the low benchmark for the Canon. Was gps or wifi running? Power management has been a problem with the new Nikons yet they smoke the Canon.

I don't know how CIPA does with GPS and WiFi, but if a camera has a built-in flash they use it for 50% of the shots, which means that those cameras will achieve fewer shots per battery charge than cameras without a flash. If they have the GPS turned on for a certain time duration during the testing, then that will certainly give a lower rating to cameras equipped with a GPS.

rrccad: No mention of the horrible banding in the d5 .. has that been resolved in newer versions of acr?

Also .. dxo which tbh I dislike their overall scores, show a subtly different dr curve for both cameras based upon differences in actual iso.

DxO defines DR as the difference between the highlight clipping point (sensor saturation) and the point where you get 50% noise in the shadows (SNR 1:1). I believe this is so called 'engineering DR', as opposed to the 'photographic DR' shown in the graph by Bill Claff.

On article Rock Solid: Canon 1D X Mark II Review (406 comments in total)
In reply to:

PanoMax: Would be nice if they used a Foveon sensor

@nicolaiecostel

Yes, it does. A Foveon sensor records different wavelengths at different depths of the sensor substrate, which is how it distinguishes between different colors. There is no color filter, and no light is "discarded", which is why you get full color information at every photo site.

A Bayer sensor makes the color distinction before the light even reaches the sensor; only certain wavelengths are let through the filter at any given photo site, while the rest goes to waste.

Edit: Of course, the light that is recorded by the middle and bottom layer of the Foveon sensor will have lost some energy on its way down, so in that sense some light is lost. But it does get recorded, whereas in a Bayer sensor part of the light is blocked by the filter and isn't recorded at all.

In reply to:

OSDphoto: The D500 scored 91%, and the 1DX Mark-II scored 89% so it did not improve at all on the 1D Mark-IV which also scored 89%. So I guess it's time to sell off all my Canon stuff and get a D500.

@OSDphoto @Jesaja

The camera category is stated on the last page of the review, just above the bar chart that shows the scoring. For example, the 1DX Mk II is a "Professional Interchangeable Lens Camera / DSLR", the D500 (and K-3) is a "Semi-professional Interchangeable Lens Camera / DSLR", and the 80D is a "Mid-range Interchangeable Lens Camera / DSLR".

The category is probably chosen based on the feature set, price and target market, but an explicit explanation or definition of the different categories would be very useful.

A Foveon sensor does gather more light than a Bayer or X-Trans sensor of the same size, because there's no color filter array that absorbs light of certain wavelengths.

The D500 is in a different category, and the scores are only comparable within the same category. Also, the scores are only meaningfully compared to the competition at the time of the review, so just because a camera doesn't get a higher score than its predecessor, that doesn't mean that it hasn't improved upon it. A camera that got 89% a few years ago probably would receive a lower score today, because we have higher expectations now.

kingslayer: $2200? Great. Another overpriced lens

Overpriced just means that you can't afford it, or at least aren't willing to pay the asking price. For someone who can afford it, and is willing to pay the price, it's not overpriced.

There's no objectively 'correct' price for a product, it's always dependent on the value perceived by the consumer. Unless you have the naive view, that a product shouldn't be sold for more than it cost the manufacturer to produce it.

In reply to:

Fujica: Leica seem to adapt the Kaizen philosophy... Where did I hear this before.

I had no idea that releasing a firmware update with some bug fixes and a couple of new features, is the same as adopting a philosophy. If that's the case virtually every camera manufacturer is a follower of this philosophy.

On article Getting up close: Canon EF-M 28mm macro hands-on review (103 comments in total)
In reply to:

rrccad: "The MTF-50 result - better correlated with perceived sharpness - tells a slightly different story, indicating only around 875 line pairs per picture height resolved, which translates to ~4.6MP, or 19% of the total sensor resolution."

the M3 sensor is AA based 6000x4000 or 3000x2000 line pairs .. as it's maximum possible (less of course for the AA filter unless you are doing deconvolution filtering)

so wouldn't 875 be much larger than 19% of total resolving?

So I'm curious because 875lp/ph on an M3 sensor would render it .. well, as a piece of crap. and by your infinity pictures, it seems to be resolving far more than 875 would suggest.

this is a new lens test setup is it not? do you guys have an explanation on how you are testing and what you are using as a baseline?

default jpg will play a big role in determining what you come up with as an example, it would be interesting if we had as an comparison, even on the M3 - ie: this compared to the 22mm as far as your MTF setup.

What he's saying is that the 'effective' resolution of ~4.6 MP is 19% of the total sensor resolution, which is 24 MP. He's not referring to the linear resolution in that statement.

In reply to:

RedFox88: You can print a 6MP image the size of a football/soccer field too. Obviously that photographer doesn't understand printing!

Of course you can print any image at any size you want, and I'm pretty sure the photographer knows that. But he probably meant printing at 300 dpi without uprezzing the image; you can't do that with a 6MP image.

Tapper123: Way too cheap.

The intended audience buys for bragging rights, not photography; give them prices to brag about at cocktail parties and golf outings. At least $20,000.

It may indicate that they have a larger disposable income than most of us, and possibly a different attitude towards money, but it says nothing about their photographic skills or how serious they are about their hobby. Again, why assume that people willing to spend a lot of money on their gear are somehow less serious about using it?

There are many skilled photographers who shoot with Leicas. Why assume that the intended audience don't buy their gear for photography? People who can afford expensive things may be just as serious about their hobby as the rest of us.

On article Second Time Around: Canon PowerShot G7 X Mark II Review (288 comments in total)
In reply to:

Alastair Norcross: A mostly fair review, but I find the complaints about JPEG image quality rather funny, and silly. Does the reviewer not know that JPEG noise reduction can be turned down or up in the camera? Or that sharpness levels can be controlled with multiple settings on no fewer than three parameters? The G7XII is an advanced compact camera. To complain about the default settings, when these can and should be varied considerably is pointless. Other than that, as I said, a pretty fair review. It's a really excellent compact camera, and an ideal everyday and travel companion.
I also find it strange that much attention at all is paid to JPEG image quality on an advanced camera such as the G7XII. If you buy this camera, you probably care about image quality. If you care about image quality, you probably shoot RAW. Given that the G7XII has very useful, and quite fast, in-camera RAW processing, there's really not much reason to shoot JPEG.

I agree, although I think we'd both be surprised at the number of users who only shoot JPEG and never change the default settings.

In reply to:

marc petzold: The Lens is exactly the same as on the original G7X - and this lens was being soft, especially at the corners. Not any as good as the RX100 Mk. III or Mk. IV Iterations.

Anyway - no EVF, no buy...it's easy as that...and Canon doesn't have 1" 20 MP sensors, they're clearly from Sony...so....what does it make sense? It's cheaper then the Sony RX100 Series a bit...but the RX100 is the Original.

Anyway, congrats to Canon to stay somehow competitive - with a Sensor from the Competition. ;-)

.edit. i've found one "feature" that's way annoying here: i can't anymore compare the rating to other cameras - from this class, the pull-down menue is gone...sad, but true.

@Imagine

Canon uses their own sensors in some compacts too, eg. the G1X Mark II. But the 1" sensor is certainly made by Sony.
