Show your Bird Portraits

Very nice series, GMCPhotographics.
Thank you, I’m visiting relatives in Falkirk, Scotland for the week. These were taken at the Scottish Owl Centre on Tuesday. I swapped out my R5 for a new R6iii last week and it’s been a good shake down experience with my new camera. I’m keeping my R6ii for low light & landscape work, my R6iii is for action, birding and wildlife.

The Next Canon PowerShot is Coming This Year

Would love to see an APS-C zoom like the G1x III. If they had the guts to make a bright prime that would be even cooler. But a zoom isn’t so bad either. Hope the sensor can read out fast enough and that it carries the water resistance and EVF of the G1X III. In fact, if they can update the battery, sensor, and processor, I’m sure it would find an audience. Also I would request the automatic lens cap like the G7X III, a cap for a compact point and shoot feels weird and I don’t use the filter ring except for NDs and a compact should have built-in NDs. If they could stretch the aperture to f/2.5 or f/2.2 on the short end that would be very cool too.
Agreed on the potential for prime with digital crop options. That would potentially fix most of the g1x3's problems imo, and tally with the popular Ricoh, Fuji and Leica compacts arguably leading the market.

For FoV but it's not the core of the message here.

Regarding the "2 stops more" I sincerly doubt his numbers are correct.
You let more light with a bigger pupil, true, but you spread it over a greater surface (focal length/magnification), that's the entire point of having f-stop (focal length/entrance pupil) as a universal value for exposure, it's already taken into account.

If we take the total light gathered formula (light intensity * exposure * sensor size), how can reducing light intensity by 2/3rd of a stop increase the dynamic range by another 2/3rd of a stop?

Let's simplify to total light to ignore exposure, assuming it's the same on both systems.

Light intensity at the focal plane is defined by 1/N² where N is the aperture of the lens (this is directly derived from the formula that allows you to calculate the F-number of said lens)

For the R7:
Intensity = 1/7.1² = 1/50.41 = 0.01984
Sensor size = 22.3 * 14.8 mm = 330.04 mm²

0.01984 * 330.04 = 6.547

For the R5:
Intensity = 1/9² = 1/81 = 0.01235
Sensor size = 36 * 24 mm = 864 mm²

0.01235 * 864 mm² = 10.67

10.667 / 6.547 = 1.6298

That's log2(1.6298) = 0.7047 stop more light
You are correct. It’s always the ratio of the front lens areas that gives the relative amounts of light falling on the image, irrespective of focal length. Here, it is equivalent to 0.7 stops.

The end of an Era: Canon 5D Mark IV marked Discontinued

I’ve been holding out. I still have my 5D4 and 7Dii. Not sure why I have this hang up about upgrading, but it just hasn’t felt like the right time. I’m a hobbiest and now that my kids are out of 4H, I don’t shoot as much. The kit works for me, but compared to today’s choices, there is no comparison against today’s camera options.

Canon 5D Mark IV 'problem' or my 'ignorance': Pls Help!

After having changed to mirrorless (owning now the Canon R6 Mark II and Canon R7), last week I decided and bought the fullframe Canon 5D Mark IV (I own the APS-C Canon 7D). Out of the box, battery and memory card ready, I turned upset/nervous with something: Only in Av (or also in Tv mode), choosing an aperture (i.e. f/8), no matter the different brightness I pointed the camera to, the shutter speed (or the aperture in Tv) remained always the same, turning the file underexposed or overexposed! never that had happened before with any Canon camera I had owned. So, or there's a real problem with the upper left dial only in Av or Tv modes (not in P or M), or... for the first time I feel dumb with the menu of a Canon camera! (No, no exposure limits reached, nor ISO problem: tried setting to 100 and also in auto). Something else to try? Please help! Thanks, guys!
check the shutter speed settings in custom functions 2 to see if it is set to a particular speed.

Be nice to see Astro versions of cameras again like the eos Ra or no AA filter versions like the 5Dsr maybe an R5a or R5sr based on the R5ii ?
Given the "reasonable" pricing to mod your camera sensor using companies like Spencers (https://www.spencerscamera.com)
provides many options (IR, full spectrum, visible+Ha, etc) then it might not be profitable for Canon. Spencers also offer new or even used bodies from their site.

Clip in filters from Astronomik means that the camera remains "normal" and yet narrow band when you want it - albeit fiddly to install at night with gloves.
You can even add back a "clear" clip in filter to restore the camera to normal after removal of the AA/IR filter

Front filters like https://capturetheatlas.com/capture-the-night-filter/ can also provide some more subtle Ha which I prefer but have a slight transmission loss.

I can't see Canon releasing another one. I think that they had an option with the R5 but decided against it.

Diffraction is based on the size of the photo site. For the same resolution sensor the site on an APS-C is always going to be the same proportion smaller and give one stop worse diffraction issues. That's physics. As resolution increases the size of those sites is smaller. If the sensor is smaller the size of the sites is smaller. The size of the Airy disc is tied to the aperture. When the photo sites are smaller than the Airy disc you are losing resolution. When they're less than half the size of the Airy disc you start getting noticeable resolution loss. The only ways to fix that are to go with bigger sensors or lower resolution sensors.
I do wonder how diffraction in practice seems to be less of an issue for higher mp sensors than the maths would indicate.

I like f16 for having deliberate diffraction spikes for light point sources at night for instance... especially with odd numbered aperture blades.
For underwater macro work with powerful strobes, f16-f18 is common for a single shot as nailing DoF focus when moving around is really hard.
For macro on land whether on a rail or stepped in-camera then f11 seems to be a common option which should still show diffraction theoretically but in practice is more than acceptable once stacked.

With higher resolution sensors, this difference between FF and APS-C is getting slimer with each new generation of camera and in a few years we probably won't compare FF and APS-C on diffraction.
