Using Catia (Mechanical engineering software), I tried to answer your question by retro-engineering the canon parts. I found a 3D model of a canon lens from grabcad.com and isolated the lens mount geometry. I compared its dimensions to the ones of my lenses and found them accurate enough. On the following view, you can see the lens mount. I used brass as ...

It's not just the weight of the camera that's a concern, but the torque that it will apply to the mounting ring on the lens (and in the camera, of course). Torque is turning force, and it's calculated by multiplying force (weight, in this case) by distance from the center of rotation. So, if we guess that your camera is 4" deep from the mount to the back of ...

The 1D Mark II was 55.5 oz. The 5D Mark III + BG-E11 grip + 2 LP-E6N batteries is about 59 oz. The heaviest flash Canon has sold in the recent past is the 600EX-RT which is 18.5 oz with batteries installed. The WFT-E8A is another 1.35 oz. Add that up and you're at 79 oz. which is about 17 oz. less than a 6 pound CCD camera. The EF mount should be able to ...

I don't have the answer for you but the answer is maybe obvious : if it were a classic mechanical problem, I would say that the lens capacity shouldn't exceed the capacity of the body (using no lens collar): If you body can support a 2 kg lens on the body mount, then the same weight is supported by the lens mount ; If your lens comes with a collar for your ...

Unlike many older manual lenses, especially primes, that have a hard stop at a lens' infinity focus setting, most autofocus lenses do not. Instead they allow for the focus mechanism to be turned past infinity. There are several reasons why this is so, but the main one is to avoid the focus motor slamming against a hard stop when focusing the lens at ...

15 second exposure with a 18mm lense with the focus cranked all the way back When you say "cranked all the way back" it sounds like you just turned the focus ring to the far limit. That's not the right way to focus at infinity because the focus adjustment for most lenses goes past infinity. You need to focus either with autofocus, or by looking through ...

As per Era's link in the comments above, photographers have been fooling people with trick photography for over a hundred years now, and your included photo is a classic example. If you see a photo that doesn't seem quite right for any reason, it probably isn't. It is entirely possible to create a larger-than-life image background like this in camera by ...

There exists software that automatically detects stars and planets in your astrophotography pictures. The technique is called plate solving, and they use a scale and rotation invariant hashing algorithm. Examples are: uniMap: a free/opensource astronomy software, [...] mainly developed to do the plate-solving (automated detection and sky catalog ...

In a previous career, I worked a lot with wildlife, including shorebirds. I've never worked as a wildlife photographer, but I did work with some people who photographed shorebirds professionally. There were spotting scopes that users had purchased adapters for to use the scopes with a DSLR. I'm not sure what brand the adapters were or for which spotting ...

I have a Celestron C5 spotting scope (5" diameter and a focal length of 1.250 meters) photographing anything from 26 feet to infinity with excellent results. Also with the right filters, I photograph sunspots and granulations. Then at night I can shoot Saturn and Jupiter. I would recommend the Celestron C5 to any photogapher.

D750 won't output video at higher resolution unless a hack or firmware update are released D750 does most probably use line skipping and it seems that even Panasonic GH4 (or other camera with full sensor readout) may produce image with fewer noise (if D750 skips 3/4 or 2/3 of lines which is not improbable) even at the same F number and with bigger ...

Nikon D750 is a full censor DSLR camera ie 35mm. this 35mm censor is meant for vedio recording purpose. while going for video recording you can only reduce ur shutter speed upto 1/30 is will cause problems of under exposure. so the best way to do this is, please the continuous shooting mode in ur STILL OPTION & then stitch it to a vedio using ADOBE AFTER ...
