The Canon W-E1 Wifi Adaptor Has Started Shipping

Speedsurfer142 said:
I live in the Netherlands and I received mine on the 29th of October. It works, but it is slow. The app needs optimising and I find that when you are connected, you can not switch easily to shooting mode. So using it in the field (I shoot rallycars in competition) is not an option. I would mis cars If I would want to transfer one or two photos to my smartphone during the competition.

What I also dislike is that the card can only remember one smart device. When I want to switch between my iPhone and my iPad I have to go through the whole WiFi paring process. This takes to much time.
Every time I want to connect to my device I manualy have to connect the camera to the device (change WiFi network) this is stupid and should be automatically done by the app.

The card is working but the app is terrible.

Thanks! Exactly what I expected from *innovative Canon*.

7D mark II still focus issues?

kklerikk said:
I have the focus issue. I have the 40D, 7d mkI, the 5dmkII, 5dmkiii and 7dmkII from one year and alf. After a wedding season I see all the photos of my second using that camera. 50% are misfocused using Canon and sigma. At first I got angry with the second photographer. But then looking at the pictures with 7dmki not missed a shot. Then we realized that it was the fault of the camera. I also used I 7dmkii for an event and 50% of the photos were wrong. If shooting a burst to a few still subject are right and others are wrong. Unfortunately between taking pictures to see and understand the problem is the past year warranty.If I make a simple camera tests the problem is not known. If few click, under normal conditions hardly the problem arises or is attributed to a personal mistake. I also noticed that the pictures appear blurry than moves. I'm selling it.

My copy now works flawlessly. Had an AF issue early on and canon determined a faulty mounted AF sensor. They replaced the mirror box and performed a complete factory recalibration. I would say the AF accuracy and repeatability is now on par with my 1dxii.

One symptom mine had was that it would not hold afma one day to the next....as if the AF sensor was loose. It would fluctuate 3-5 afma clicks which of course is quite a bit of variance with many lenses.

Rather than sell it, maybe have canon check out the AF sensor and do a factory recalibration. Might be worth paying for it if it's out of warranty than take the loss selling it. It is in fact a great camera and should work exactly as you expect it should.

Beetle photography

SkynetTX said:
Hello Maximilian!

Thank you for your detailed answer and advices.
I am glad that you appreciate it.

... and started to take macro photos this spring so I'm still learning how to use it. I will try to raise the ISO to 400.
Try out also ISO 800 or even 1600 and look if the results (esp. sensor noise) are still pleasing you.

Most of the times I'm using the Aperture-priority AE program of the camera and select at least f/8 aperture to have a wider DOF. Tripod is a must for me as I try to get as close to the subject as possible and am using the EF-25 II extension tube many times to increase the magnification.
I think that is totally okay but also try to avoid to narrow apertures like f/32 because it makes short shutter times difficult and also you will have some sharpness limitation because of diffraction.
When I am working with a fill flash or FED ring light I am working with full manual and Auto ISO, so I have fill control over shutter and aperture, but I'll have to watch for the ISO not getting too high.

Until next beetle season begins here's a stink bug: Rhaphigaster nebulosa.
You can improve your technique during the winter with other subjects ;)

Have fun and good luck.

Question about anti flicker feature on 5DS and 5DMKIV

The anti-flicker simply detects the light frequency (50Hz theoretically?) and forces the camera to wait a fraction of a second when the light reaches its brightness peak (on the sine wave). I think if your color light has a green or blue shade when it's dimmed and no shade when it's on peak, the anti-flicker may help, otherwise it will be probably useless.

Canon EOS Rebel T7's are Next on the DSLR Schedule [CR2]

mileage varies by use and user. while it will work for some people, using 2 prime lenses with 24 and 50 mm focal length is not necessarily a better solution than a 18-55 zoom lens.

i do have a few prime lenses but find myself using the 18-55 STM quite often. to me, prime lenses are specialists, one-trick ponies, exactly the right solition for a specific task, when i know in advance what that task/situation is going to be. more often, for all not-preülanned photographic situations - e.g. "walkaround" in my city or other cities, or alpine ventures/mountaineering in summer or winter - i prefer the flexibility of a zoom. often, i cannot freely chose my vantage point. if i want/need to go small and light, i want a compact camera (like SL1 or in my case an even smaller EOS M) with one compact, light, optically decent, not too expensive universal standard zoom lens on it.

18-55 kit zooms had a poor reputation since earlier versions (pre STM) where optically mich weaker. Canon has corrected this in the current EF-S and EF-M 18-55 IS STM zooms. and nikon) 18-55 kit zooms. I find IQ astoundingly good for such small and cheap lenses. of course there are optical limits - first and foremost f/3.5-5.6 - but sharpness is no issue (unless it is a bad copy). calling current EF-S/M 18-55 STM IS zooms "useless" or "no sharp images in less than ideal weather/light" as someone did in an earlier post is totally undeserved and untrue bashing.

so my advice to (first time) Canon "Rebel" or EOS M buyers is: think about "what kind of images do you want to capture? in what types of situations? what scenes, what subjects? planned/unplanned shootings?". depending on answers, i'll recommend either 18-55 STM without hesitation and/or other prime or zoom lens/es.

Tether Tools Case Air Wireless Tethering System

I have a iusbportcamera2 that I bought on a flash sale from B&H for $169. It fits in the camera shoe, has a sd card port, and will charge a iPhone battery if needed.

The software setup is not clearly explained, but I managed it, I can hook to my Wi-Fi network and remotely tether (live view can control stills and video). Same with my smart phone and tablet. Smart phone, tablet will direct connect as well. It runs all day on a battery charge, and has a fair range outdoors, but trying to control using a tablet from inside the house is difficult, I have to sit by a window and range is short. I do not have outdoor Wi-Fi, or that would be much better. Works on Android,, iPhone, mac, and pc.

This seems well suited for video, it does some of the other common features such as focus stacking as well.

https://www.bhphotovideo.com/c/search?Ntt=iusbportcamera2&InitialSearch=yes&N=0&c3api=1641%2Cbing%2C2761706221%2C108011504843

Something to consider as well, it is definitely not so clunky as the CamRanger.

Review - Canon EF 16-35mm f/2.8L III Lens by TDP

By chance I had a short opportunity today to play around with the new 15-35 III.

What I noticed to far:
- build quality is excellent, feels almost the same as my 24-70 II (also looks the same). Therefore I have no problem with the increased weight
- picture quality seems very good, especially in the corners
- vignetting is pretty obvious and strong but not the 4 stops that TDP shows (at least from looking on the photos, no scientific comparison). I can definitely live with it.

Just my 2c

OmniVision Debuts Second-Generation PureCel®Plus and PureCel®Plus-S Technology and Product Families

HTML:
<em>OmniVision’s Newest Pixel Architecture Brings Exceptional Low-Light Performance and Increased Dynamic Range to Advanced Imaging Applications</em></p>
<p>OmniVision Technologies, Inc., a leading developer of advanced digital imaging solutions, today introduced its latest advancement in leading-edge pixel technologies: second- generation PureCel®Plus and PureCel®Plus-S. In keeping with OmniVision’s tradition of delivering industry-leading image sensors, the second- generation PureCel Plus technology offers significant improvements over the previous generation, such as higher full-well capacity (FWC), better sensitivity, increased signal-to-noise ratio (SNR) and enhanced low-light performance. Though the initial development was focused on supporting small-pixel products for mobile applications, this technology will ultimately benefit many other image sensor applications.</p>
<p><!--more-->

OmniVision’s second-generation PureCelPlus technology showcases various performance improvements, including:</p>
<ul>
<li>20 percent increase in FWC, enabling higher dynamic range.</li>
<li>A newly introduced composite metal grid (CMG) structure, which increases pixel quantum efficiency and enhances sensor low-light performance, leading to a 12.5 percent improvement in sensitivity.</li>
<li>Improved deep trench isolation (DTI) structure, which further reduces color crosstalk and improves the SNR10 (low-light performance index) number by 10 lux.</li>
</ul>
<p>These structure improvements also enable small-pixel sensors to have better tolerance to incident light angles. This in turn allows imaging systems to use lower F-number lenses for better brightness, and to realize lower module heights that are essential for slimmer phone designs.</p>
<p>“Maintaining good image quality and sensor performance for small pixels in low-light conditions has always been a challenge in the digital imaging space. OmniVision has delivered increasing engineering advances over the years to address this market need,” said Dr. Song Xue, senior manager of sensor technology at OmniVision. “Our second-generation PureCelPlus technology enables our end users to capture high-quality, high-resolution photos, even in challenging lighting environments.”</p>
<p>OmniVision’s second-generation PureCel Plus-S technology will empower new families of compact 20-megapixel and 16-megapixel sensors. The 20-megapixel OV20880 and OV20880-4C and the 16-megapixel OV16885 and OV16885-4C are designed to deliver high-resolution images to high-end smartphones across a variety of lighting conditions.</p>
<p>The OV20880, OV20880-4C, OV16885 and the OV16885-4C are currently available for sampling and are expected to enter volume production in the first quarter of 2017.</p>

Firmware: Canon Announces New Firmware for Cinema EOS C300 & C300 Mark II

Yep - that audio-"feature" is a thing i never understood...every smartphone would record high fps with audio... so i am happy to see canon still cares about us users out there.

LOVE THAT SHUTTER ANGLE UPDATE - finally we can switch through framerates without worring the shutter is double the fps or not! NICE!

I love this camera for simple reasons:
- small formfactor (dont use big baseplates/rigs/v-mount batteries) - perfect for motorised sliders and gimbals with a great weight
- quality picture with a fast and easy menues (could be even better and faster - but its okay)
- D-AF does a great job 70% of the time
- color grading is a pleasure with clog3

I would love to see:
- false color on the c300-2

- a BP-a60 (or bigger BP-a90) WITH DTAP to power a external monitors (!!!)
(no battery manufacture wants to do that because the amount of c300-2 cameras out there is too few as they say...)

- a hardware and/or firmware upgrade to realise higher fps with and without centre-crop
(i could understand that 4K60p/50p is probably a thing just for the
c700...but atleast more fps at 1080p with and without centre-crop would
be great. ( if for example the many video-signlal-outputs wouldnt work for higher fps or other features were disabled while high fps, i personally wouldnt care - i just need one video-feed out of the camera at the same time - but DAF while High fps would be mind blowing!)

I would pay a hardware upgrade to keep the camera up-to-date
and competetive any time!

Go canon, go!

Why Focus Peaking Would be Useful on a DSLR Camera

I've used a focus screen with a split prism on my 1D MK III. Not very accurate on a DSLR though. Its like that focus confirmation light, it tells you that you are approximately focused.

Live view with magnification takes time, but it is accurate, and when tethered using my large monitor with additional magnification, I can focus to an extreme accuracy just where I want it.

Canon Q3 Operating Profit Nearly Halves on Post-Brexit Yen Strength

Woody said:
Oh, for you nay-sayers who think the world of Canon is crashing down because they announced a 50% reduction in profits for the first 3Q of this year due to a rising yen, you should read what's happening to your beloved Sony et al.

oh no, it's JUST canon ;)

interesting.. they are forcasting 3.8 million cameras (including P&S) down from 6.1 a year prior.

another huge drop, three years in a row. Sony doesn't break out ILC's probably because they are too scared that people will find out the real facts.

Or Nikon.... 1000s of jobs to go there....
http://asia.nikkei.com/Business/Companies/Nikon-to-cut-1-000-jobs-in-Japan

But... its not due to Cameras. Nikons camera sales are up some 50+ percent. Nikon is being smart, their Semiconductor Fabs are losing money due to poor sales so they are getting ahead of the curve by re-assigning workers, and may offer voluntary early retirements or layoffs.

The Japanese companies still do not layoff employees wholesale like US companies do, but they are finding ways to shift and retrain the workforce as well as offer early retirements.

They do rent contract workers, and, since they are not employees of the company, they don't count them when their jobs go away.

Patent: Canon Develops Variable Optical Low Pass Filter

Mt Spokane Photography said:
I wonder if there is a specific application for this? Adjusting object recognition accuracy due to temperature changes seems like a limited application, is this a issue for normal DSLR users?

I wonder if its going to appear soon?


"Conventionally, light measurement of a single-lens reflex camera has measured the strength of the light with the photometry sensor installed around the pentaprism via the light measurement lens in the luminosity of the object image currently imaged on a focusing screen. It is using image sensors, such as CCD, for the above-mentioned photometry sensor separately from imaging sensors, incorporating the object image currently imaged on the focusing screen, and distinguishing the form and the color of the incorporated image in recent years, and object recognition and color detection are performed and there is a photometry device which aimed at improvement in functional. When the spatial frequency of an object image has a response more than the Nyquist rate of an image sensor, a false color occurs and it may become impossible usually, for an image sensor to recognize a right color on a sensor.
[0003]
Since a high spatial frequency response is required also of a light measurement lens in order to perform object recognition when an image sensor is used for a photometry sensor, a false color may occur like an image sensor. When a false color occurs in a photometry sensor, the color of an object cannot be recognized correctly but there is concern which causes erroneous detection. Therefore, image sensors, such as CMOS currently used for the imaging device, are processing arranging an optical low pass filter or applying a digital low pass filter by the image processing after imaging into an image formation optical path, etc., in order to suppress generating of a false color.
[0004]
Although the low pass filter is inhibiting generating of a false color by restricting the spatial frequency response of a lens and stopping the high spatial frequency component of an object image, the resolution of an object image is deteriorated and deterioration of image quality produces it. In order that the usual imaging device may perform focus adjustment to an object and may always take a photograph in the position of a focus peak, the image quality degradation by a low pass filter is a degree which is satisfactory practically. However, the above-mentioned photometry device is difficult to mount a focus adjustment mechanism in view of the miniaturization of an imaging device, and low-cost-izing.
[0005]
However, if the temperature of a photometry device also changes because environmental temperature changes, a focus gap of a lens occurs, and since adjustment of a focus cannot be performed, the resolution of the object imaged to a photometry sensor will be deteriorated. Therefore, when a focus gap of a lens arose, deterioration of the resolution by focus gap of a lens was seasoned also with deterioration of the resolution by the low pass filter effect, and resolution required for object recognition may not have been acquired.
[0006]
The following technology is proposed about the prevention from image quality degradation by a low pass filter in the imaging device which does not have a focus adjustment mechanism. At the Patent document 1, a spatial frequency limit effect is provided with a variable optical low pass filter, and the focusing state of a photographing object is detected, and by weakening the spatial frequency limit effect of a low pass filter according to the amount of gaps of a focusing state, though deterioration of resolution is suppressed, it has composition which inhibits a false color. "

From what I can tell, the purpose of the patent is effectively to improve the resolution and color accuracy if iTR metering in Canon cameras. All the specificity aside, sounds like a good thing to me, and since iTR is being used in more and more Canon DSLRs, it should have fairly broad application in that context, even if it isn't something that the user directly sees day in and day out with their camera. It should just mean better AF with more consistent lock and tracking.

CMOSIS Announces New 48mp CMOS Sensor

Canon Rumors said:
<p>Its pixel offers 64dB optical dynamic range at full resolution and up to 68dB in subsampled 4k mode, and the imagers benefits from the implementation of sophisticated new, on-chip noise-reduction circuitry such as black level clamping to enable it to capture high quality images under low-light conditions.</p>

64 dB is what, about 11 stops?

CMOSIS is doomed!
