Stunning. I've watched Peregrins exchange food in the air but no pictures.

On photo White-tailed Kites in the A big year - birds 2019 challenge (13 comments in total)

Is this 2 birds fighting for the same mouse (or) like peregrine falcons, an air transfer of food from parent to child?

On article Hands-on with the new Peak Design Travel Tripod (308 comments in total)

I have an Oben travel tripod and it is decidedly fiddly. Small, light, but sort of difficult to use. I use a small travel tripod just for waterfalls so I just ordered the aluminum Peak Design. If I need a larger tripod, I'll use my 35 year old Bogen 3020.

I'm not understanding your banter. Top hole. Bally Jerry pranged his kite right in the how's your father. Hairy blighter, dicky-birdied, feathered back on his Sammy, took a waspy, flipped over on his Betty Harper's and caught his can in the Bertie.

I'm looking at my pictures of that face of the Terminal Tower and I can't see anything round. Great shot. How did you get up there?

I worked as a steel tower lineman so I am use to heights but looking at this makes me feel nervous. Good job.

It looks like they are building scaffolding. I did something like this about 30 years ago inside a very large boiler.

We have a Frank Gehry designed building in Cleveland. I just can't imagine what the acoustics are like. Good picture though.

MacM: interesting, I don't think i've ever heard of this before. I wonder how many lumens of output it gives, and if the UV really works. It seems very expensive though. I've got a UV LED at home but for one it heats up very quickly and the second thing is that even though it's supposed to peak at 365nm, it seems like it only emits purple light. It's strange in fact because even though the emitted light is purple, the reflection is visible light (RGB)!

I have no experience with this product but I do have a lot of experience with trouble shooting fiber optic systems. A 650nm "visible fault locator" is invaluable when trying to find a fault in a fiber system. It's a quick and dirty test to see where the fault (a fiber break) is. You will also want an OTDR if you are really working in fiber. You can see with your eyes 650nm light. It's red. Don't ask me what shade of red, but you can see it, thus "visible fault locator", 650nm.

brycesteiner: add a tiny camera to one of them and you could use it to do your own colonoscopy!!

Try having a colonoscopy and an endoscopy at the same time. I don't want to make anybody feel paranoid but (you should).

Has anybody had a good experience with with this device? Never heard of it but I'm interested if it works well. A little leery if it doesn't fit well in a hot shoe.

On article Canon patents 400mm F5.6 catadioptric 'mirror' lens (220 comments in total)

I have a Vivitar series 1 800mm f-11solid cat. I had it in storage in my closet for about 30 years. When I looked at it, the front lens cover which was rubberized plastic had disintegrated. It didn't harm the lens but now I have a tin foil front lens cap. It is not really the greatest telephoto lens but if I have to go out to 1200mm on my APSC camera, this is the ticket.

In reply to:

Old Cameras: When I used to ride bicycles a lot, when I was younger, there were two kinds of riders you typically ran into while riding: those who rode, and those who focused on their equipment. You can certainly do both, or neither, but being overly focused on your bike and having the latest frame, brakes, aero wheels, index shifted derailleur, titanium this and carbon fiber that - those guys were typically not strong riders and didn't ride very much. I have nothing against a Leica but marginal differences in resolution and sharpness aside, it's an aspirational object of desire rather than a tool. A good camera won't make a bad photographer's pictures better any more that a titanium bicycle will make a week rider faster or stronger. Photography is not about the camera.

This is a critique of a Leica camera and "Darkroom_Fine_Art_Pro" who doesn't like criticism of Leica criticizes Sony. Why is this about Sony? Get a grip man.

MacM545: 80 megapixels is a lot! What lens would you need to be optically superb enough to justify that many pixels?

What 80 mpx's? It says 20.3 mpx's.

PPierre: Well, combined with an EM1 mkII, it might be quite an impressive combo :) But yes, i have the feeling I would go another road if I were to need such shallow DOF. All that matters in the end is the photo you get. However, were they to make a 75f1.2...

Both are equivalent to an f2.4 in the 4/3 system which isn't bad considering the 1.8's in the Sony APSC system are equivalent to f2.7.

On photo Belgian F-16 in the Inverted flight challenge (6 comments in total)

Nice picture. Tried to get shots of the AF Thunderbirds a few weeks ago from a boat on Lake Erie just off of Cleveland and the results were not great. Really great colors on the F16 and I gather it was not in stealth mode and neither were the Thunderbirds. They were in display mode. The primary mission of a display flight team is "recruiting". How do I know that? "I aint tellen nobody".
