I suddenly feel emasculated in the presence of all that "big glass."

Well...look closely at the second to last pic, of the camera in "auto" mode. Maybe that will perk your spirits a bit. I had to look at it a couple of times to figure out what made that image so unique.

The big glass is very impressive, no doubt. Coupla those lenses there cost more than a good house in most states.

Thanks - some great shots, and some surprising apertures.

Thanks Douglas! Side splitting!!

Oh, those settings? You should've asked me mate! That'll be KAMA Settings/Positions 65 66 67 68. Yeah that was the model missing 69 and 69b. It's now a downloadable Preset - you can just . . er .. insert it.

Grazie



very very funny

That website triggers my "dangerous website warning" in my Trend Micro. Something called "joke".

Spot, absolutely amazing collection, and great juxtaposition.

Grazie, excellent insight. I spent ten times longer, staring at that one. Is "Stonefield" still around? He might have something similar on his cams, although perhaps a toned-down version.

The freshwater dunk is one I've heard of and almost resorted to when my wife put my son's iPod through the washing machine a few months back.

I've got a feeling the little kid photographing the croc (or gator?) was about to learn that those creatures can move amazingly quickly when provoked. Hopefully he didn't lose a leg in the process.

One thing I wonder--why do all those photographers carry around such big refractors? Surely a compact folded-mirror system would give just as much aperture, resolution, and focal length, yes?

Catadioptric ("folded-mirror") telephoto lenses have been used, but never become popular, for good reasons imho (I used to shoot with an amazingly compact 8/500mm).

The f/stop is fixed at whatever the design comes out to, usually f/8 or f/11, and it's downhill from there because of the T-stop loss from the secondary mirror blocking a fair amount of the incoming light.

The bokeh (visual appearance of out-of-focus objects) also looks outright unpleasant, like something out of a science fiction film.

Canon made a 5200mm lens for border patrol use in remote regions, they chose to make even this monster a traditional straight telephoto design.

And straight telephoto lenses make much better coffee table legs too, as we saw in one of these pix :O) What a blast, thanks Spot!

...and there is a third type of telephoto lens design, using special Diffractive Optics to get a very compact design (even more compact than a folded mirror).

Canon offers a 70-300mm f/4.5-5.6 DO IS USM (Diffractive Optics Image Stabilization Ultrasonic Motor Autofocusing) telephoto zoom that is only 4 inches (100mm) long, and if you put it on a typical Digital SLR, it becomes a 112-480mm zoom equivalent, filling up the viewfinder with a butterfly from 4 feet (1.2m) away.
