Nikon D7200 boasts low-light AF improvements and increased buffer depth

" Nikon's D7200 has some big shoes to fill. The D7100 was one of our favorite midrange DSLRs of the past few years, and though it's by no means a radical upgrade, the D7200 presents some notable new features. It has a 24.2MP CMOS sensor with no optical low-pass filter, an updated 51-point AF system sensitive to -3EV, a much larger buffer that can take up to 27 Raw images at 6 fps, and Wi-Fi with NFC.."

Hobby photographer, now retired due to an nearly fatal accident at work. I worked as an pilot and intensivist. Since childhood interested in photography. My "SSD" got reformatted and has still a lot of damaged clusters. But trying to learn a lot of my favourite hobby again.  ;)

Lenses / Canon Patent for EF-EF-M Adapter with Improved Auto-Focus Speed
« on: February 24, 2015, 03:42:53 AM »

"Egami (translated) spotted what could be Canon’s best move to push their mirrorless cameras. A new EF-EF-M adapter that should deliver better AF speed when using EF and EF-S lenses. While the AF performance of Canon’s new EOS M3 is excellent with the native EF-M lenses, AF performance is limited when using EF lenses via the currently available adapter. If Canon puts such an adapter on the market it would a huge selling point for the EOS M3. Access to Canon’s extended lens lune-up, and same AF performance as with native lenses!"

Good news for all M3 interested photographers....

Canon General / Camera sales in Japan 2014
« on: February 20, 2015, 07:09:49 AM »
"BCNranking published the full 2014 camera sales date in Japan. The good news is that Sony dethroned Olympus and is now number one in the mirrorless system camera market in Japan. And in Japan mirrorless is very strong and on par with DSLR in terms of cameras sales. The (unsurprisingly) bad news is that Sony really holds no more any meaningful share of the DSLR market:"

Canon is still leader in DSLR market

EOS-M / Question on USM speed on M/M3 with L lenses
« on: February 14, 2015, 03:37:49 AM »
Does anybody know, if the speed of an USM powered lens, used on an EosM/M3 shows an delayed reaction when focussing?
I do not mean the AF speed od the camera. A member of our local photoclub has this problem, when he uses one of his L lenses with the adapter on the Eos-M. The original 55-200mm lens works much faster. The camera focusses and about a second later, you can hear and see the reaction of the lens. This phenomenon does not appear with his 55-200mm.

I just ask, because I am a little bit willed to buy the M3, if it has an good IQ.

An interesting article on an new sensor: "to double the light-input surface area of each pixel"

EOS Bodies / Re: Interview With Head of EOS 5Ds & EOS 5Ds R Development

Interesting comment on the pricing od the 5DS:  ;)

"If you think $3000 is a bit steep, you might be interested to know that Masaya Maeda - Chief Executive of Imaging Products at Canon - agrees. He tells us he's saving up his own money to buy one. We'll be publishing an interview with Mr. Maeda very soon."

fount at:

Received my exchange Eos 6D yesterday. Eos Info 1.2 tells me 0 shutter releases.

That's obviously bogus, no shutter leaves cps w/o at least a quick test - so they've reset the count and you have no way of knowing what the actual physical count is. But nevermind, I doubt many 6d have a high count and chances are they really replaced the shutter, so you're better off than before. As already written above, I'd exchange my 6d for a refurbished one any day :-)

I know. You are right, this cam looks well "refurbished"... Only the mirror lacked of an fingerprint.
My 7D has now over 100.000 shutter releases, and works well. If the 6D, (which I use for not-moving objects or landscape) will be alive 25.000-30000 releases from now on, I will be satisfied.



Enjoy your photography. :)

thanks... photography? well, better call it "knipsen"....  ;)

EOS Bodies / Re: DR from 5Ds will be 2 stop better then 7D mk II
« on: February 10, 2015, 01:20:24 PM »
Can someone explain this to me:

The silicone is colorblind, so you need filters to constrain it's response to certain wavelengths of light and collect the information needed to create a color image.
Beginning with the 5D2 Canon found a way to increase the sensitivity of their cameras: by using filters that allow more light to pass. On the downside the the difference in response of R,G and B pixels to a defined color was reduced, using the same tone curves would have lead to washed out colors. Nothing a higher saturation can't fix. At the first glance at least, as both the reduction of input data as well as pattern noise creeping into the demosaicing become apparent.
Getting the color response at least back to 1Ds3 levels would be welcome...

Ah, ok, I see....
This phenomenon has been claimed by an German foto-magazine and they reduce the rating of the camers. Ad hoc, I think, they call it dead leaves....

Can someone explain this to me:
"I'm told that the colour filter array of the 5Ds is much closer to the 1Ds mk3 than the 1D X"


Found @
"Some interesting (and yet unverified) news coming from people testing a pre-production EOS 5DS surfaced.

Northlight Images received a comment from a user testing a pre-production 5DS with DPP4. It appears that at low ISO the dynamic range of the EOS 5DS is 1.5-2 stops better than the EOS-1D X, while high ISO performance (i.e. ISO 6400) falls slightly behind the EOS 7D Mark II. The same comment/rumor says the 5DS sensor is similar to the 7D2 sensor from a technological point of view (puzzles me), and that the 5DS sensor has been tuned to deliver the best possible low ISO performance.

Another comment says that the colour filter array of the EOS 5Ds is much closer to the EOS-1Ds Mark III than to the EOS-1D X."

"Sony Artisan Brian Smith: “someone might just make a 50mp camera for less than 3700 bucks!”

Sony Artisan Brian Smith commented after the Canon 5Ds launch:

    Canon fired the first shot in the Great Mega-Pixel War of 2015, announcing a pair of 50.6 mp Canon 5DS cameras – This is just the first shot! Expect to hear more announcements soon… Who knows, someone might just make a 50mp camera for less than 3700 bucks!

He is likely “hearing” the same rumors I got….sounds exactly like the A7rII to me ;)

Sony has now plenty of time to “fight back” with the A7rII as the Canon 5ds preorders will start on April 30 only at Amazon. And shipment is June/July."


I read this on
"So just to let you dream a bit …here is what I got and what you don’t have to take seriously for now:"

“Sony has a new global electronic shutter sensor that will be put into our new flagship e-mount camera. The top shutter speed is 1/32000 with flash sync capabilities at that speed.
Sensor resolution will be well above 50MP
It will have In body stabilization like the A7II
A new type of AF will be implemented, it is like DFD from Panasonic but faster.
196 points of autofocus covering 94%
-2 ev af acquisition
faster autofocus than current a6000 CIPA rated
no 4k on this camera
NEW Bionz X2 processor, 70% faster per core (quad core)
no pricing on camera just yet, expected to be $2700-$3000 for body
TWO new lenses will be unveiled: 85mm Zeiss 1.8 with the performance of the 55mm Zeiss. 135-400mm Sony G 5.6 lens. pricing will be $1300 and $2000
Also: a new A mount camera will be announced, the same processor and DFD like AF module will be in the new camera, as well as SLT flip up mirror mechanism..."
