On Sources of noise part two: Electronic Noise article (234 comments in total)
In reply to:

Mssimo: Question: As far as shot noise... Would a APS-C camera with a speed booster have the same low noise performance as a full frame assuming the same lens is used?

A light bulb went off now, I guess large(r) format lenses spread out light reducing the "hot spots". I guess thinking of it as a little boy burning ants with a magnifying glass. Given a fixed light source, the smaller the circle the hotter the light. Medium format circle would cause a very soft light across the huge sensor leading to more dynamic range.

Maybe I need to read it again but is shot noise has to do with the quantity of light correct? So if an adapter reduces the image circle, you would have the same amount of light but in a smaller area. In other words, if an speed booster allows APC shooter to use ISO 100 vs ISO (400-800) on full frame, the image quality when it comes to Shot noise could be the same.

OBI656: Fuji and Sony will pretty soon replace positions of Canon and Nikon in market place ...

I think canon and nikon will keep making the best DSLRs on the market, but that market will grow smaller every year. To keep this from happening, they need to stop the bleeding and we have not seen anything from canon or nikon that show that they are on top of the game. At least canon makes lots of money off printers.

coody: Why can't it be designed better from the beginning but has to go through the firmware updating? Can the firmware perfectly resolve the flaw? Usually the more firmware updating has, the more problems the product has.

Why not make a perfect camera that will last forever, never have any issues, never need upgrading and always take perfect pictures? This is the real world; as soon as we hear about a new camera, they are already working on the next model or next firmware. They did not need to release this huge update but they want to camera to stay cutting edge and maybe win over customers. It is also less expensive than to retool a factory.

Canon and Nikon are not going away overnight and they will keep the large share of the DSLR market. The key here is the DSLR market will shrink and level off just like the 35mm film market has. My guess is that non Pro will only own celphone camera, 80% of the semi pro and pro will go to mirrorless/large sensor cameras. Canon and nikon will first get rid of mirror and optical VF on (D5300/T6i) class cameras but keeping lens compatibility. Sports cameras will stick around for longer as DSLRs but 4-6K video cameras (20-40MP) will take over sports since they will shoot at 30-120fps non stop for the whole game. Im a little sad to see DSLRs go away but it will happen, maybe 2 years, maybe 6 years...but it will happen.

Kodak also had a "foothold". Also, android is a operation system based on linux kernel. Apple sells phones not operating systems. Would you like to share apples phone market share or should we talk operating systems? Before you say linux vs apple, iOS is also based on linux.

@prossi Im sure samsung, motorola, nokia and others said the same thing about apple about 8 years ago. If you think about it, camera phones outsell DSLRs by crazy numbers...so its a mute point. Canon and nikon are going to die off and replaced by many players including celphones/mirrorless.

You don't have to update your camera. Most users loved the camera as is. If your Nikon, maybe you can rename the model X-T1.10 with new firmware and handful of very minor changes and start charging MSRP again.

Mssimo: Im willing to bet we will have a autofocus crisis when this camera hits the market. This is the beginning of the end of phase detection auto-focus and one of the last popular DSLRs before the big decline. Mirrorless is going to hit strong and hard, only obstacle they still have is subject tracking and lens selection. Auto focus accuracy, single shot AF speed, image quality, shutter speed, HUGE viewfinders, and tons of momentum. I will miss SLR but im excited to see the biggest change in photography since analog to digital.

I was speaking of the Leica type 240 and Noctilux 50mm f/0.95. Even nikon has come out with a guide on the D800E that recommends using liveview focus vs PD for most accurate focus. On top of all of that, most lenses have an amount of focus shift when stopping down. Its always best to focus at the fstop you plan on using if you have the light to do so. Contrast Detect also can focus on any part of the sensor including the edges and has great face detection.

Everything has its tolerances including focus systems. As MP goes up, PD systems cant keep up with the accuracy. Same with lens quality (This is why Zeiss made the Otis line of lenses). PD when its on a separate sensor (as in DSLRs) becomes very difficult to align and calibrate. It is better than it has ever been but its still a calculation of what focus should be on the sensor. Leica has this issue with rangefinder cameras, many have to go back to factory for 3 months to get calibrated. High MP sensors and f.95 aperture lenses is a DOF nightmare.
In a few words, Phase Detection AF is like eyeballing a measurement and Contrast Detect is like using a ruler. Both will need to get better but eyeballing is showing signs of its limit.

Snikt228: It's interesting and at first glance the $399 lens is a good deal, but when it requires a $300 adapter it pushes it to the doesn't make sense anymore realm. Unless of course you already have the adapter or have a lot of M-mount lenses which might benefit.

Would have made much more sense to just make it native E-mount especially since it's designed for only A7 series.

My guess this is only the first in the series and they might add other mounts to the system. I wonder if they ever would come out with a autofocus version of the adaptor......

Mssimo: How much money could canon be saving by making own CMOS chip? Im sure with the volume canon has they could get a exclusive custom built sensor from sony and still call it a canon sensor. Olympus turned around when the OMD line used a sony sensor for the first time. Before that sensor technology very weak.

As far as I understand, canon designs and fabricates own sensors and it seems this is holding them back. I can only imagine how much it costs to retool a fab for a newer/smaller process, especially considering the yield will not go up due to fixed sensor sizes.

Maybe also a mixup with the first set of images. D810 whole frame should have a wider field of view correct? I'm viewing this on mobile version of the site.
