Help needed: Af settings on 5D Mark IV for surrounding birds in flight

Hi Daniela - tracking moving subjects is a whole new learning curve and it is so easy to believe you have nailed focus, then you look at the picture in Canon's DPP and see the focus point is past the bird. Evenmore so if the gull is 50 metres away.
If the bird is against a uniform background (sand dunes, blue sky etc) then it becomes easier. If it is flying past a complex background (scrubland, trees) it is so easy for the AF to pick up the more contrasty background. Also, anything moving towards you makes it so much harder for the AF to keep with the change in distance (but it is easier to keep the AF point on the face). Start off with something moving parallel to you.

Experiment with grab shots as much as you want, but it is easier to practice if you see the bird from some distance, get the AF point on it and let the system track it for a second or two before firing the shutter (google 'Canon pump focus' for more explanation)

And practice, practice, practice...

First Impressions: Canon EOS Rebel T7i/800D

No... just no. It's like this person hasn't used a xxxD before.

On xxxD bodies without rear dial (ie everything other than t6s) you turn the top dial to M, then use the front wheel to set shutter speed. If you put your thumb on the Av button on the back (which is actually very comfortably placed), the wheel then controls aperture. These controls even work in LV. Or, you can press Q and use the arrows and set and control it on the screen. Or you can use the touch screen. And when not in LV You put your thumb on the live view zoom out button and use the wheel to adjust +/-.

On every xxxD model before t7i, it is definitely not:

there are no obvious direct methods to take full manual control of exposure settings using the EOS 800D.

... unless you've never used a xxxD or read the manual... or just pushed buttons...

And anyways, if you've gotten to buy a $700 SLR body, you should learn how the manual settings work, even if they're not your favorite way of shooting :D

Firmware upgrade suggestions for all bodies, (sensible ones).

digital paradise said:
Custom Settings - "detail set" for the AF-ON and * buttons. Canon please add Drive Mode to the list of options.

You got that right. The 1DX2 enhanced programmability of those buttons gives so much greater AF versatility! You can change modes just rocking your thumb and shutter finger, instantly.

Which Canon lens is most in need of updating.

rfdesigner said:
in this case it is equivelent, depth of field, speed, field of view are all equal, effectively it would be the same lens with a little variation in the rear group to focus the same light over an APS-C sensor rather than a FF sensor.

Sure... and then you lose the size advantage the OP wanted.

not disagreeing.. I blame physics :D

Zeiss Milvus 50mm f1.4 vs Canon EF 50mm f1.8 STM: 10x the price and 10x better?

Milvus is great, but I have to hand the better AF to the $90 EF lens. It has better consistency; and, oh yeah, it actually exists. ;)

Note to Sigma: remove AF and charge $2k.


Did you ever shoot with a good manual focusing lens?
Sometimes manual focus has a better consistency than autofocus...
And a good autofocus may work, but shooting macro f.i. manual focus us key. And here the canon lenses are not great...

CPS Removes Certain Lenses & Cameras from Serviceable List

Re: CPS Removes Certain Lenses & Cameras from Serviceable List

BeenThere said:
I've had two Canon lenses that died due to autofocus no longer working and, at the time, they were discontinued and unrepairable at either Canon or any independent repair shop that I contacted. I sold one for parts and still have the other one. It's a fact of life with these lenses that they will stop working at some point and not longer have any value. Same thing happens with televisions and many other electronic based items.

It's a matter of cost. If I spent $10K on a television, I would expect it to be serviceable for at least a decade.

Review: Irix 15mm f/2.4 @ LensTip

Viggo said:
I've been look in a bit at this lens lately, and it seems quality control is horrible. My preferred shop said they tested three copies of the ones they got and they had so heavy vignette that they sent them back and refused to sell them. I see some tests, think it was dpreview, that says the vignette is pretty great, and lens tip claims it's horrible. One guy sent me a summary of his experience and said the first one he got had 5 stops of vignette that never cleard, even at f11. He sent it back and got another one that was "much better" and he had a couple of samples that proved the difference, so wth? :P

How very interesting! Thanks for posting. I'm glad I went with the Samyang 14mm 2.4. Which I expect to see 3/13.

I was also recommended the XP 14 f2.4 instead, but I wanted a uwa mostly for fun so I won't be spending XP 14 money on one as of now.
Looks like you made the right choice :D For me, I'm lusting after the Canon 14 L II again, I loved that lens when I had it.

The... horrible suspicion

sigma = statistical standard deviation. 2 sigma (precisely 1.96 for larger number of observations, usually taken as >>100, but usually rounded to 2 for ease and good measure) is the 95% confidence interval. 6 sigmas is way further our on the bell curve. As Mt spokane pointed out, 99.99966% confidence interval. Haven't checked, but sounds about right.

Standard deviation = Square root of sum of squared deviations from mean divided by number of observations minus one.

hope that helps. If not, google standard deviation in statistics.

parts for Canon 180mm f/3.5 macro

you might have to adapt/modify from a find at you local hardware store
other two options would be a getting a aftermarket tripod ring or (even harder to get) find someone that would lend you that screw and washer and get it "copied"/machined. It is possible to make a mold and then cast one in hard polymer/resin, but still think the hardware store is you best choice

Canon EF 70-300mm f/4-5.6 IS II USM Review (Dustin)

Talys said:
I bought one, just for the nano USM. AF is not quite as fast as 18-135 (which is so fast that it's scary), nor as quiet, but it's still better than any other lens in either category, IMO. I really like the IQ on it for the price and focal range. On a tripod, it's a beast; without, you need to up ISOs a little because most of the range is f/4 or smaller.

The build quality is really nice. It has a premium and solid feel to it, and a modern look, just like the 18-135 USM.

My biggest criticism of these lenses is the electronic focus ring. I hate not having full time MF, especially on the 70-300; having to hold the shutter halfway to focus is annoying, and I manually focus all the time with birding because the AF may focus on the wrong subject (wrong bird, tree branch, whatever).

I'm completely with you on the MF issue. That's my least favorite thing about STM/Nano USM

Insta360 Air Arrives in US and Europe, Turns Android Phones into 360° VR Cameras

HTML:
<em>Real-Time Image Stabilization on the Way</em></p>
<p><strong>SHENZHEN, Mar. 7, 2017 </strong>– The Insta360 Air, a smartphone add-on that instantly turns Android phones into 360-degree cameras, is now on sale across the United States and Europe.</p>
<p>“The Air is what we’re all about — cutting-edge technology that empowers people to capture and share experiences just the way they live them,” said J.K. Liu, CEO and co-founder of Insta360. “We can’t wait to see what the world’s Android users create.”</p>
<p>Android and iOS account for more than 90 percent of the world’s smartphone users, and the release of the Air means all of them can now enjoy seamless 360-degree photography and live-streaming. The Insta360 Nano, launched last year, offers a plug-and-play 360 experience to iPhone users.</p>
<p>The Insta360 Air’s simple, intuitive design makes capturing and sharing 360-degree content easier than ever. After connecting via USB Type-C or Micro-USB port, the Air uses a smartphone’s display as its viewfinder, allowing users to capture 360-degree stills and videos with the Air’s dual fisheye lenses and camera-interface app.</p>
<p><strong><a href="https://bhpho.to/2lXWS6O">Insta360 Air is available at B&H Photo</a></strong></p>
<p><!--more--></p>
<p>With real-time image stitching and integrated live-streaming support for YouTube and other platforms, users can broadcast immersive experiences to the world or share 360-degree content to friends on a host of popular social media — including Facebook, Twitter, WhatsApp and Messenger — directly from the app interface. Users can explore content on a screen or through a VR headset for an even more immersive experience.</p>
<p>The Insta360 Air experience isn’t limited to mobile. The Air also serves as a 360-degree webcam on Skype and other video-chat applications after connecting to a PC’s USB 2.0 or 3.0 port. 360-degree webcam support for Macs will also be introduced in a future update.</p>
<p>The Insta360 Air captures 3K photos (3008 X 1504 pixels) and 2.5 K video (2560 X 1289 pixels) at 30 frames per second. Weighing only 26.5 grams and with a diameter smaller than a ping-pong ball, the Air is also the most portable consumer 360-degree camera on the market.</p>
<p><strong>Real-time image stabilization coming soon </strong></p>
<p>Insta360 is committed to providing ongoing support to both devices and users well after purchase. Air users can expect regular updates to the Insta360 Air app and camera firmware. Among the most-exciting updates on the horizon for the Air is the planned addition of an all-new feature, real-time image stabilization.</p>
<p>The advanced image-stabilization technology corrects unwanted vibrations and sudden directional changes as they happen, letting users capture smooth and steady live streams and video.</p>
<p>The technology will mean a vastly improved experience for viewers using an immersive VR headset. And by reducing the variation between adjacent frames of a live-stream or video, it also offers big bandwidth savings. Real-time image stabilization is set to be released via app update in the coming weeks, and Insta360 Nano users can expect the feature as well.</p>
<p>Priced at $129 USD, the Insta360 Air is now available via Amazon in the U.S., U.K., Canada, Spain, Germany, Italy, France and Japan. U.S. consumers can buy the Insta360 Air offline at B&H and Fry’s Electronics, with other regions also offering offline sales at select retailers.</p>

Canon Lens support ended for certain lenses

Seven years is probably short for the expensive lenses, e.g. the EF 800mm f/5.6 is as expensive as car, and one would expect it to have a comparable service period.

Then again, those expensive lenses are probably owned by people who make a living with it, and therefore...

1) Get a tax deduction on the equipment, making it cheaper than its list price.

2) Have it insured, and hence will be compensated if the lens is bricked.

3) A business will probably not own the same car (at that price point) for that long either.

Sigma to Finally Bring a 70-200mm f/2.8 DG OS Sport Lens in 2017 [CR2]

Ah-Keong said:
hope this Sigma 70-200mm SPORTS / ART can match the performance of the Canon 70-200mm II

::)

Match? It should exceed the performance of the Canon, at least in terms of image quality. We should be more concerned with focus breathing, stabilization, and AF speed, accuracy and consistency.

I agree that the IQ would be surpassed, I hope that issues like focus breathing, stabilization, AF speed, accuracy and consistency would be "matched".
