On Canon announces EOS C100 Mark II article (221 comments in total)
In reply to:

MediaDigitalVideo: I want this under my X-mas tree.
Canon is playing Santa Claus again.

I have a GH4 and it's not a better camera for 1080p as unlike the C100 it skips pixels giving moire/aliasing. It's much better for 4k (wonderful even for moire/aliasing) but you do get quite a bit of rolling shutter, which again the C100 is very good for. Also it doesn't have the professional Cinema lenses the Canon does (not that I care personally as I can't afford them).

marcio_napoli: Typical DP review crowd. They all look for specs, actually knowing very little how to use it in the real world.

It's just about numbers, on gear heads minds: DR numbers, MP numbers, ISO numbers, and now, 2k vs 4k.

In just a few years, 4k vs 8k... numbers, bla bla bla, numbers.

If my statement above doesn't cut it, the mighty ARRI Alexa is a 2k camera only.

Do you know what the "obsolete" 2k Arri Alexa means to the movie industry? It's basically the most acclaimed digital movie camera ever.

And guess what, few, very few Hollywood level movies are actually produced in 4k.

Very, very few.

If Hollywood is not ready yet for 4k, do we really think a bunch of gear heads on DP review are really in THAT need for 4k ?

Oh dear...

The Alexa is 2k8 now, but you're right it's much loved by DPs for it's very filmic look, great ergonomics plus NO rolling shutter. BTW the C100 is supposed to be very good for rolling shutter too.

Movie studios tend to rent kit, so they don't care about future-proofing, just what's the best tool for the job right now.

Nindy5: 8mp, I wonder If it line skips, I love that look.

It's a 4k sensor (8MP) from which they create 1080p by using 4 sensor pixels per video pixel, so you get R, G and B information for every video pixel. (The C500 uses the same sensor to do 4k.)

Francis Carver: Another laugh-fest class feeble opening from Has-Been Giant Canon. This camera with its AVCHD codec, slow frame rates, low-end 8-bit color quality, HD-only resolution, and HDMI jack is a stark reminder how amazingly Sony had stolen the wind out of Canon's sail, as well as out of just about everyone else's sail.

The $8,000, 4K capable Sony PXW-FS7 D-film camera is 12x the camera than this new" Canon wannabe. This thing is old and limping already, and it is not even scheduled to ship until years end.

A lot of the ENG teams I see in London use Canon cameras, so they seem to be doing okay there...

On Canon introduces new $78K 50-1000mm cine lens article (164 comments in total)
In reply to:

photofan1986: I might get one for my Panasonic GM1 with a Speedbooster adapter :D

It should be okay, the m43 Speedbooster doesn't use the whole image circle... The SpeedBooster is a 1.42x crop, vs. 2x normally for m43 (so normally a 50mm lens = 100mm equiv on m43 but with SB = 71mm) a Super35 sensor is a 1.4-1.5 crop vs. FF so I think you're probably okay!

Tal Shachar: If all camera manufacturers would join to create common lenses standard to fit all camera brands, I would consider buy expensive lenses, well not that expensive but expensive and big collection of them.

For Cine lenses you could give it a snappy name like PL... oh wait...

In reply to:

samfan: T5.0-8.9 doesn't sound impressive, at least in the lower range (and I doubt it's gonna be T/5 until 999mm). How do cine people deal with bad speed in low light? I get it that with 1080p it's not such an issue compared to 36 MPx prints, but with 4k I guess things start getting noisy.

A lot of Cine cameras have a native ISO of 800, rather than the 100-200 of stills cameras.

IMHO a non-issue, worth a read:

http://www.wncoutdoors.info/2014/09/no-the-forest-service-is-not-planning-to-charge-you-1500-to-photograph-the-wilderness/

Excerpt:

"every news article I’ve seen has failed to incorporate those (rules for requiring a permit) into its story ...

Still photography—use of still photographic equipment on National Forest System lands that takes place at a location where members of the public generally are not allowed or where additional administrative costs are likely, or uses models, sets, or props that are not a part of the site’s natural or cultural resources or administrative facilities.

JohnMatrix: It's official then. The EOS 100D is a girlie camera.

Actually I've seen more guys than gals with them, they like the smaller size relative to the other DSLRs.

quezra: Missed opportunity Canon. You could have stuck a Hassy label on it and charged 10 times that much. No wonder Canon is dying!!

This is the Canon who makes more profits selling cameras than everyone else put together? If they are dying everyone else has been cremated...

Photato: Canon is stubbornly clinging to the SLRs.
They are so clueless lately this is not even funny.

Canon and Nikon make a pile of money selling DSLRs; all the mirrorless manufacturers lose money on every camera they sell, hmmm do you think they might be the smart ones by moving slowly into mirrorless...?

Pritzl: Dang it! You guys missed the most significant question: X-Trans RAW processing support by 3rd party software. JPEGs are nice, but until RAW processing (particularly in Lightroom) becomes completely hassle-free, it's hard to accept Fuji X-Trans for your only camera. Any chance for a follow-up?

Adobe haven't updated the underlying X-Trans algorithms since 7.4, in fact they rarely make such basic changes, having a second go at X-Trans was very unusual, I can't think of another sensor they've done that for.

BCSeah: second pic, the one with the fishing rod, says "24mm FX format".
isn't it 35mm format? or 135?

I assume it's a typo for 24MP.

Spectro: The mass consumer has no need for 4k. Dpreview spec photographers are just yapping. There are a lot fewer videophotographers then photographers. That is why gh4 and sony a7s aren't flying off the shelves. Mass consumer dont have 4k tv nor internet speed to watch 4k youtube. But since the competion has it, it is time to offer it in 2015. I do expect movies studio and live sport to have the best video quality 4k or better, not the local commerical video. Those are genertic and 4k wont help it.

I expect a mirrorless dx and d3xx next year. Use the f mount for mirrorless so most nikon users can use their lenses already. Or f mount adapter, that is fine too if it af fast. I dont shot spray and pray photography nor professional sport, so i could care less about the d3xx. But nikon created a camera for them and shouldnt abandoned the user base. I would guess that is the first camera released next year for nikon. Dx is 2015 where fx were mostly udpated in 2014.

falconeyes - I added a like but the GH4 is only Full Sensor readout in 4k, not 1080p (4-pixel combine on-sensor) or 720p (9-pixel combine on-sensor) which only use about two thirds of the pixels in the 16:9 sensor area. The A7s does do full-sensor 1080p, but its 4k mode has a lot of aliasing for some reason (the GH4 is very clean).

I think the most important thing if you use an X-Trans sensor is the selection of Raw processing software, and Lightroom shouldn't be on the list.
(SilkyPix Pro 6, Capture One and Iridient Developer should be, the first two from: http://chromasoft.blogspot.it/2013/03/lightroom-44rc-and-capture-one-versus-x.html which is the end of a long series of posts by a Raw software developer and the last one following some discussions I had with Thom Hogan.)

In reply to:

lacikuss: Good questions, however I thought that these were not fully answered. Comparing Sony's Interview with this IMO Sony shows focus and desire while Canon doesn't.

Unfortunately for Canikon, IF sensor technology evolves in such a way that smaller sensors close the IQ gap to almost cero OR Lens technology is able to compress size/weight for any sensor size then they lose their system's advantage.

Smaller sensors can never close the gap as most noise in photos is due to the random nature of light (which DXO don't include in their measurements) and so a sensor that captures more light will always win, provided it has access to decently fast lenses.

Avobanana: "We use the best sensor"
"Our sensor is the best"
"We have been very serious in mirrorless from the beginning"

Lies and denials. I was holding on switching away from Canon. But maybe I should do it now. It's one thing to lag behind at something and totally another to deny it.

I frequently shoot spherical panoramas with a 5DmkII, where you keep the same exposure for all the photos and don't want to blow out the highlights. This means you need to bring the darker photos up quite a bit. I find that works fine for me. If I was really after insane shadow pulls Nikon or Sony might be better (except they don't have suitable lenses), but it's good enough for me...

knightsJayTana: "So in your opinion your sensors are currently the best on the market?

Yes. In the EOS 7D Mark II for example the sensor we’ve used is improved compared to the previous generation, especially at high ISO and in shadows. There’s less noise."

This is hilarious. Improvement over last generation but way beyond dated compared to the rest of the cameras by other manufacturer.

"We are very focused on getting the best image quality. I’m not sure what measurements you’re looking at but when it comes to dynamic range for example we consider image quality as a whole, from low to high ISO sensitivities and on balance we consider our sensors to be the best.

My ideal camera is one that can take a picture in any environment from complete darkness to the brightest sunshine."

Any environment? Look above, you cant even make it right. I mean the sky Mr. Maeda.

This is silly, Canon have always been as good as anybody at high ISO, their only issue was low-ISO DR due to off-sensor digitisation adding noise when the ISO was low.

In reply to:

Dave Oddie: I think when asked about dynamic range the comment about having the best image quality (note not DR specifically) from to low to high ISO is about as close as you are going to get to an admission they don't have the best DR.

Optimizing image quality across all ISO's is their excuse for lower DR.

Re the touch screen... I think on the 7D it's all about pro-style speed in sports/wildlife. The tracking is intended to follow moving subjects, rather than to be moved around quickly to other targets and a touch screen allows for problems due to accidental touches (for example I have it disabled by default on my GH3 and GH4 once I accidentally moved the AF point to the edge of the screen on a couple of key situations). I also suspect they wanted to keep the cost down for their target customer base, it isn't a general-purpose camera in any sense.

samsamsamsam: Please compare by yourself and do not believe the propaganda. That Canon Sensors are so bad.
The Canon 5d m3 (ISO 50) has less noise then the a7 and more DR and more DR then A7s, only the a7r is better in Noise and DR. Tip, You have to look in the highlights.
Show me that I am not right. just look at the RAW test images in PS.
I dont anderstand that everybody say that Canon Sensor is so bad. What bad is about Canon is the Pixelcount only 22 and no Pro Mirrorless. But for more Pixel you need better lenses and less Shutter shake and so on. But I hope they will make it soon.

The problem Canon has is DXO highlight low-ISO DR where Canon loses out vs. the competition that digitises the data on-sensor. The Canon sensors are great, but taking the data off-sensor to digitise throws away a lot of the advantage at low ISO. At high ISO this doesn't matter (as the extra noise gets added after the ISO amplifier, so the effect rapidly decreases with ISO). Also DXO aren't do big on rating some things that Canon are good at with colour.

That said if you want to do 4-5 stop shadow boosts at low ISO Canon isn't your camera, but if not it's as good as anything else, coupled with some great lenses. (I push the shadows quite hard on my Canon and it works for me, but I don't go to extremes like some people, or just look at DXO results and guess what they mean.)
