Really cool photos, I especially like the third. The motion in the wings and the expression of the mallard are great.

Thanks, ThomasTH! I wish I could say I planned the slight blur of the wings, but I thought my shutter speed was just on the edge of freezing motion. Oh well, I was on the wrong side of that edge.
But I like the slight blur regardless.
As far as the expression, apparently I choose to photograph the duck that is employed by a modeling agency

Just wondering if the 'A' for Astronomy line was excluded on purpose or by accident or was just felt it didn't meet the criteria ? The EOS 60Da (a being astronomy or astromodified)

Saw a distant raptor 80-100m away so pointed the R5ii with the RF 200-800mm + 1.4xTC at 1120mm. It works pretty well and I was able to identify it as a Buteo buteo, the European Buzzard, only 400px x 500px in the image. For amusement at 1120mm, a portrait of a House Sparrow at 5m away (cropped).

Amazing details in the second one.

I really like the hawk in this dark blue sky.

Red Tailed Hawk, sittin on a limb! Taken with my Canon R8 and RF 600mm f11

I’m curious why there’s total silence about this fact here and on DPReview. By the way, it seems to have fixed that nasty Error 70 issue in Multiexposure mode that I used to encounter.

I didn't even realize there was a new firmware release, I was kind of relying on this thread for that but maybe I missed it or I'm following the wrong one.

But thanks to those who updated me!

+1 Thanks Richard.

Nice article

Time to time Alan is very helpful - actually always !

I agree!
But I'm still waiting for the "Consultation Fee" invoice...

I really like the last one. Well done, Nemorino.

Do you have any trouble with your tripod vibration?

Click to expand...

Depends on the situation: I use a small travel tripod which is not the most stable. As You see in the "making of" pictures, I removed the center column to get closer to the floor. If I have the camera at the end of a fully extended macro rail vibration is of cause a problem. But I use the remote control and allways a delayed shutter of two seconds. And the Laowa lens is much smaller then the Canon MPE 65.

Now two stacks made with a MT 24 flash

R5m2 + RF100L
135 frames close to mfd


and 35 frames

Your central thesis that dynamic range is proportional to pixel density is a very common misconception. Dynamic range is proportional to sensor area, not pixel size (pixel density). This is made quite clear on the photonstophotos site in the Notes under the graph he plots of dynamic range vs sensor area. https://www.photonstophotos.net/Charts/PDR_Area_scatter.htm
"Notes:
Photographic Dynamic Range increases as sensor area increases.
This is because the Signal to Noise Ratio (SNR) increases roughly by the square root of area.
Therefore the x-axis on this chart is the square root of the sensor area.
Note that pixel size does not enter into this relationship."

The dynamic range of the V1 sensor is what you expect from that relationship. The V1 sensor 18.4mm x12.3mm = 226mm^2, the R7 22.3mm x 14.9mm = 332mm^2, and FF = 36mm x 24mm = 864mm^2. The photonstophotos plot of the dynamic ranges of the V1, R7 and R5 fits nicely to that pattern

Two for the price of one, a gecko and a lovely flower.

So cute!!!

Great summary

The center column definitely is something I hadn't thought about but is obvious now that you told me. Thanks!

I found a site that does tripod and head tests: The Center Column: “The Center Column is dedicated to providing quantitative data on tripod stability.”

See: https://thecentercolumn.com/

I'll repeat my comment from when dpreview did something similar (for lenses):

"USM" can mean several different things:

* Ring USM = Powerful Ultrasonic Motor, most useful when there's a fair bit of glass to move and you want to move it quickly, was pretty standard on most higher-end Canon lenses for a long time. Still used in RF lenses.

* Micro USM and Micro USM II = small and lower end USM motors, not much used now. The II is a shrunk version of the original.

* Nano USM = Linear Motor, the best current option on many higher-end lenses, two may be present, or can be combined with a VCM motor, or just used alone.

Wish he was mine...
