All other things being equal (build quality, low dispersion elements, etc.) are there any significant differences between fast (f/1.8-2.8) and slow (f/5.6 and slower) lenses when shooting with a f/11 or smaller aperture?

Canon is full steam ahead as far as lens development goes, as a whole slew of optical formulas have appeared at patent offices.
These are the latest EF mount optical formulas. It’s possible that these are Cinema lenses as they appear to be close to parfocal.

My Verdict: a Highly recommended lens.

After first slight disappointment: Knowing the lens since a couple of years this copy is confirming the good things I know about this lens - but I have to give the quality assurance department in Samyang the task to check the lenses they give out a bit better. This copy needs at least a readjustment.. And in terms of useability (nice buttery manual focusing) and weather sealing it is really step up against the original version..

On the other side: it is a very special lens - this is the nature of ultra wide angle lenses. It has some flaws but there are excellent workarounds.... finally what you get from the lens is surprisingly good...

For whom is this lens for?

It is made for owners of the R-Mount cameras - but the EF version shows similar results.
Everybody who likes a lightweight high performance lens.
When to take the RF Mount version instead of the EF mount? This is a very good question. For my taste: if you have decided to got with the R-Mount and/or you do discontinue with EF Mount: go for it. It is lighter and easier to handle.
It is more a lens for enthusiasts, for people who like to shoot manual focus.
But manual focus is so much fun to use on the Canon mirrorless cameras....
But the lens has a bit of weaknesses too:

It is not native RF: I guess a lens designed for the 54mm bajonett diameter and the short flange distance can be even smaller and lighter
I miss an EXIF chip - this would be even better
Not a real weakness but a wish to the designers @ Samyang: instead of a color mark please but something you can feel that you can mount the lens on the body without looking at it....
But if I look at the lens at a glance: I give the lens a highly recommended!!!

Canon Inc. has released its 2019 Q1 financial results.
Canon presentation summary of the imaging division:
In the first quarter, sales of interchangeable-lens cameras were down 19% to 850 thousand units. This reflects the combined impact of accelerated market contraction for DSLRs, in particular, entry-level models, and economic slowdown in China, which is a sizeable market for interchangeable-lens cameras.
The habit of capturing images with smartphones with improved cameras has become a part of the daily lives of consumers. As a result, the market for entry-level DSLRs is contracting at a pace that exceeds the outlook we had at the beginning of the year. That said, we expect the user base of professionals and advanced-amateur, people who value the image quality and expressive possibilities afforded by cameras with large sensors and an abundance of interchangeable-lenses to remain. For the market overall, however, we expect the trend of market contraction to continue for...

Wouldn't it be nice if there were a medium format camera from Canon along the lines of the RP? Just call it the Canon MFR. Nothing fancy, just a basic camera in MF that would come in at < $2,500. I don't mean MF size like the Pentax 645Z. More a sensor the size of the one found in Phase One's 100MP XF camera (53.7×40.4mm). Then just a couple of really good zooms. Anyway, I know Canon would probably never do this, but it is nice to dream. (I have no idea what a sensor that size costs.) Never mind. I just looked it up. I need a permanent roof over my head first. Stupid dreams.

What do you the Crop sensor camera will be?
Will Canon bring out a yet cheaper FF then the RP?
RP cheaper verison
24 mp
Autofocus like the RP
Digic 8 processor
5fps
No 4k
1080p 120fps
Same wieght or size as the RP
$799-$999

Update After speaking with a couple of people, it turns out that this image sensor has no chance of ever making it to a consumer product. One person said its likely application is security if it ever actually makes it into production.
Without giving specifics, the source said that the format of the document removes the chance of this being for consumer photography applications.
 
A leaked document shows that Canon has a full frame 63mp image sensor in the pipeline. There is no way to verify this information or this document’s authenticity, but from reading the document below, things do look legit.

Any of you all attempted that combination via Novoflex or Fotodiox? I know I'd likely lose electronic functionality between body and lens. I'd appreciate any thoughts or info you might share.

I've found the feature to tag images with GPS data form my phone works quite well but often the App disconnects. I sometimes turn camera off - don't know if that matters as bluetooth remains on. Also maybe I should stop battery optimisation on phone for the Camera Connect App? Any other tips?

Its been about a month or five weeks since I got the EOS R, and I'm trying to find the right words to describe just how I feel, without coming off as a fanboy or just gushing over things.

What I like -
Focuses in light that the 5D3 and 5D4 cannot, with lenses they wouldn't dare to even try with.
The focusing seems faster, livelier on servo, even a bit livelier on one shot.
The granularity of the configuration, whereby (almost) any setting can be assigned to different buttons.
The ramp up of viewfinder brightness in low light which gives my 60+ y/o eyes a break in low light. The OVF of the 5D3 (and borrowed) 5D4 are just so dim in low light by comparison.
The vibrationless, sort of "Leica M" exposures.
The size, or lack thereof.
Ditto for weight.

What I don't like -
The viewfinder ramp up, in low light focusing. I think what its doing is raising the gain on the sensor to "focus" then returning it back down to its set sensitivity? If you make a big change in subject distance in low light it seems to white out, focus at about the time the viewfinder catches up with the gain increase, then settle back down. This all takes a moment.
The EVF blackout when the camera is idle for a bit. I've not found a way around this, but maybe there is one. Shooting hoards of motorcycles at Bike Week, I had to learn to "activate" the EVF with a flick of the shutter release or back (focus) button, as the traffic light turned green, so I'd have the EVF on as the bikes passed. Its just one less thing I'd rather not think about, and at times the camera wasn't ready, so I just shot anyway. It focused, and exposed ok when I did that, but of course framing wasn't terribly great.
The few limitations on features and functions that can be assigned to buttons. Wha? I praised that, now I'm knocking it. Well... one thing I like to set on the fly is the metering mode, especially when I'm out all day, varying light from side light to high noon sun, varying background, varying subject, and the way I'd like to render the images. For instance, I took a break from shooting bikes to photograph some of the locals and (many) passers by at Bike Week. In the middle of that, there'd be a great custom car or bike rolling down Main Street. It was a button fiddle to reset metering modes, and so I just left it to Evaluative, and did "ok". Bracketing is not an option as the time is insufficient with moving vehicles. Anyway, the only way I've found to set the mode is to get the Q button set up in "metering mode" so its fairly accessible. That took a bit of manual sleuthing to do. This is no deal breaker, but you can't assign that "function" to other buttons.

All of that, just me of course, YMMV

Bottom line - I gave my 5D2 to a friend to get them into full frame photography. I'm sure they'll appreciate. It will go well with the 7D I gave them a few years ago.

I intentionally did not get the RF 24-105/4 L with the camera body. My concern was having two lens lines that were only interchangeable "one way". My outlook has changed. I'll probably get the RF 24-105, and just dedicate it to the R body for 90 percent of what I shoot. That's my go to lens for years. I can't see me keeping the 5D3 too much longer, maybe a two years - depending on what Canon does with the R series bodies. Switching from OVF to EVF and back, and controls being totally different, takes some getting used to.

So anyway, just my thoughts, comments welcome.

Hi Guys!

I had an backpack incident on Monday (silly, as I´m looking for an new one). The result is an heavily damaged 5DIV. It is not repairable (CPS).
I do not want to spend the money for an 1DXII as an successor might be coming in one year, so I will stay with the 5D class.

My question:
Would you go for an Eos R with the batterygrip, or stay with the 5DIV?

I own a lot of Canon glass, mostly using the 600LII+1.4III for birding and some primes around 16mm to 100mm for landscapes.

Does onyone have experience with the 600LII+1.4x on both bodies? How fast is the AF working? I read yesterday, the 5DIV is faster, but do not know if this is true.

Thank you a lot for advice
Daniela

There has been a flurry of sensor talk over the last few weeks, though we haven’t posted much about it because most of it cannot be confirmed with any sort of certainty.
We’re now told that a brand new 32.5mp APS-C sensor is slated to arrive in an EOS M camera as well as in a DSLR sometime in 2019. This comes shortly after being told that an all-new 24mp APS-C sensor was on the way.
The source claims they’re “100% certain” that this sensor is coming in 2019.
I cannot confirm this information, so please take it with a grain of salt. It is rated [CR1].

whatever happened to the rumors Canon had a competitor to the Sigma/Tamron 150-600, Nikon 200-500 "reasonably" priced zoom coming?

The follow-up for the Canon EOS 7D Mark II has been talked about for the last year or two, with varying degrees of information being passed onto the rumor sites. This has obviously lead to a lot of speculation about the future of the flagship APS-C shooter Canon.
We’re now being told that no EOS 7D Mark III is coming down the pipeline from Canon. Instead, we’re going to see a replacement for the EOS 80D that will move slightly upmarket to cover the prosumer and enthusiast APS-C shooters.
We’re told that there will be an EOS R camera body that will come to replace the EOS 7D Mark II. However, we weren’t told whether or not the replacement would still be APS-C or if we’ll see a full frame camera in its place.

We’ve heard an APS-C EOS R camera body prototype exists, but Canon themselves have said their future is in full frame cameras due to their higher margins and the desires of the marketplace.
Maybe we’ll see two separate “sports” EOS R cameras in the next year or two, one to get...

With the Canon RF 70-200mm f/2.8L IS already announced, it was only a matter of time before an f/4 version of the lens hit the market. This patent shows that Canon is actively working on such a lens.
Unlike the RF 70-200mm f/2.8L IS, the f/4 version in this patent appears to show an internal zoom lens design.
Canon RF 70-200mm f/4L:

Focal Length: 72.20mm 130.45mm 194.20mm

Total Lens Length: 215.54mm 215.54mm 215.54mm
BF: 25.98mm 25.98mm 25.98mm


Additionally, there is also an optical formula for an EF 58mm f/1.4 with what may feature a dual AF motor focus system according to Canon News.
Canon EF 58mm f/1.4

Focal Length 57.79mm

The Canon RF lens lineup will obviously include more affordable non-L options, and this patent shows Canon is working on such optical formulas.
The back focus on the RF 28mm f/1.8 is really short, which is quite interesting.
Canon RF 28mm f/1.8

Focal length: 28.80mm
F-number: 1.85
Half angle of view: 36.91°
Image height: 21.64mm
Total lens length: 80.30mm
BF: 7.00mm

Canon RF 50mm f/1.8

Focal length: 48.50mm
F-number: 1.85
Half angle of view: 24.04°
Image height: 21.64mm
Total lens length: 95.00mm
BF: 15.80mm

We had previously reported on the possibility of an RF 50mm f/1.8 IS coming sometime in 2019. With the coming IBIS in Canon mirrorless cameras, we may not see IS in these types of lenses to reduce size and weight.

Does anyone know if it's considered safe for a camera sensor to take a photo of a welding arc with no special filter? I've seen multiple instances of lasers taking out sensors, and obviously prolonged photos of the sun is a non-no, but does anyone know with welding arcs?

I can say that I have actually done this before with a Rebel T3i. I was too inexperienced with photography to know any better, and I set up the camera on a tripod with it zoomed right in on where I would be welding, and triggered the camera remotely. The photos were really neat, and it doesn't seem like it damaged the camera or sensor, but did I just get lucky? I would love to do this again now that I'm more experienced and could probably take better photos, but is it safe for the camera? (Obviously I know that looking at a welding arc through a DSLR would be dangerous, but I would not be framing the shot at the same time that welding was actually taking place.)

We’re told that the next generation of Canon CMOS image sensors will begin with an all-new 24mp APS-C sensor inside Canon’s next DSLR and EOS M cameras.
What sorts of improvements we’re going to see in the next generation of sensors wasn’t divulged to us, but we’re hoping to see some major advancements from Canon in this area.
Canon is putting resources into updated dual pixel AF, quad pixel AF and stacked image sensors if we go by the patents we’ve seen over the last year or two. APS-C video shooters might also appreciate line skipping being introduced to get rid of the crop. It’d also be nice to get 4K DPAF in these new cameras.
The next ILC cameras from Canon are an EOS 80D replacement as well as an update to the EOS M5. Neither of these cameras can afford to recycle the current 24mp sensor by just adding direct read 4K.

The internet seems to be recycling our original post about a 70+mp EOS R camera with IBIS being next EOS R camera to be released.
We haven’t heard anything additional since early March about the next EOS R camera. We were told then that the camera would be 70+mp, have IBIS, two card slots (one being SD), and we’d see the return of the joystick.
It makes a ton of sense for Canon to introduce IBIS on a high-resolution EOS R, as camera stability gains higher importance as you increase megapixels and 70mp+ is a lot of pixels.
On a side note, I’ve experienced a learning curve for getting sharp images from the Leica Q2 and it’s likely down to the doubling of resolution over the original Q. You may have...
