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.

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 (270 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.

On article Fujifilm X-Pro2 versus X-T2: Seven key differences (358 comments in total)
In reply to:

Sammy the Squirrel: The X-2Pro is best for people who want the look of it and the key differences illustrate that best. You can do what the XPro2 does with the XT2, and more, for less. Game over.

How is the X-Pro2 more discreet? It's not significantly smaller, assuming the side-by-side image above shows the cameras to scale. In fact, its rectangular box shape makes it look slightly larger.

dialstatic: 'Our goal is to satisfy everyone'

It's fun to speculate on what he meant in the context of the X-system development, but I'd just like to point out that this is a horrible life motto.

Unless photography actually puts food on your table, nobody really *needs* a camera. As with any other hobby or pastime, it's something we do because it's fun, enjoyable, relaxing, and maybe even therapeutic for some. So, apart from the relatively small niche catering to professionals, the entire camera industry is a "feel-good industry". And if a Fuji camera works for some people, what's wrong with that? Don't like it, don't buy it, it's as simple as that.

Tical: "Ironically, I get the sense that it is the rangefinder-style X-Pro and X100-series that have attracted more attention among traditional enthusiasts, possibly because they are so un DSLR-like."

THIS!
That's why I'm not particularly fond of the X-T series and enjoy every day more my X-Pro2, even with zoom lenses only (I have no primes yet): it is a VERY competent camera offering a plethora of shooting options, and adapting itself to the lens and to the shooting situation in an absolutely unique and peculiar way. It's pure magic, and although I'm not particularly fond of the AF-C custom either, it's a pity they decided not to include that in the forthcoming FW upgrade, given that there are no hardware limits in the X-Pro2. This sounds more as a marketing thing, so hopefully they won't leave the XP series slightly behind. Maybe after they sell enough XTs...
Anyway, these really are wonderful times for the photo people.

"When Sony hired Olympus to do them designs for mirrorless full frame cameras"

This is the first time I've heard of this. Any source?

AFAIK, Sony's investment in Olympus and their joint business venture, has nothing to do with camera design. They are developing medical technology together, and buy components from each other. Have either company made official statements about designing cameras together?

vmk01: To satisfy everyone is very bad goal.

Yes, if you try to do it with one and the same product. However, aspiring to build a complete system that contains options for every kind of user, is an admirable goal imo.

steelhead3: American corporate meets French way of doing business...Good Luck Apple.

Well, being one of the top 10 largest economies in the world, surely France is somewhat competitive, at least economically. And culturally speaking, many would say that French culture is one of the most influential in the world.

In reply to:

AirJarhead: I understand Fuji may be trying to differentiate the X-Pro2 & XT-2, however it is a little to late for that. Fuji wasn't saying the X-Pro2 was a snap-shot/street-journalist only camera when they announced it. They marketed it as a PRO camera.
I take issue with the X-Pro 2 not getting the custom AF-C modes for the following reasons:
-The X-PRO2 has the word PRO in it, and costs more. So everyone should (rightly) assume it will have pro features.
-Given Fuji's history of firmware updates, I expected all features rolled out in the XT-2, would be ported over to the X-Pro2 (except 4k, I figured they wouldn't port that).
-There is no reason for them to keep the AF features separate.

While I agree with your sentiment, I also think that just because a camera is marketed as 'Pro', it doesn't necessarily mean that it's targeted at all kinds of professionals. Reporters, portrait photographers and sports photographers have different requirements, for example. Both the X-Pro and X-T are top of the line, but targeted towards different users.

Bhima78: His reasoning against touchscreens are clearly from a lack of imagination. Saying people use the viewfinder to compose... well sure, but you could also use a touchscreen to choose a focus point while looking through the viewfinder. Also, its easier to change settings with a touchscreen than chimping away at a D-pad, let alone having the option for touchscreen focus/fire shooting. If its "too confusing" as he says, it could be defaulted to off, and have the customer decide if they want it on.

It works excellently on current Panasonic bodies, so it's only a problem for those who haven't tried it.

On article Samsung launches first removable UFS memory cards (177 comments in total)
In reply to:

William Koehler: Just as SD/SDHC/SDXC has achieved market dominance, someone has to come up with yet another flash card format. Good luck with that, Samsung. Maybe you should ask Sony how well MemoryStick worked for them, seeing as Sony has made almost everything they sell work with SD/SDHC/SDXC.

"It's backed by all the major players? I don't see ANY available on B&H."

I don't know of any company that first releases a product using a new format, and then decides to support that format. Support for a new format usually comes before the products using it.
