Hello,I can't get my Neewer Speedlight NW565EX or Neewer Speedlite 750II flashlights to work with my Canon M50. It just won't fire.The camera is on manual exposure mode. I am testing on different shutter speeds and all 3 modes of Flash Slow Synchro. ...
Hi!It is known that one of reasons for noise appearing in long exposures is increasing temperature of sensor. This drives me to a question:Is it true that long exposures will be less noisy in cold nights than warm nights? I mean, comparing more-less ...
Hi!I have a theoretical question.I always thought that maximum magnification ratio of a lens can be calculated when given (maximum) focal length and minimum focusing distance. In fact things seem different.A popular canon kit lens EF-S 18-55 mm f/3.5...
Hi! Is it possible with canon itself or canon with magic lantern, to correct lens distortion in-camera, with no lightroom, no photoshop etc.? Yes, I am asking about distortion, not aberrations or vignetting.
Hi!The link below shows a photo that I took with my EOS 700D. The contrasty edge between building and sky is innaturally jagged - this happens often, particularly when a sharp edge is nearly orthogonal. I guess that's caused by antialiasing filter. I...
Thanks for the links! I've actually browsed through the first article before but I missed a point which is the clue, I guess: "for a fixed focal length, magnification is inversely related to subject distance. This relationship isn't linear, i.e. if I...
Yeah, but still, sorry for my stubborness, what else can determine a lens' reproduction ratio, if not MFD + focal length? Assuming MFD = 0.2 to 0.25 m and focal length = 50 or 60 mm, we should always get similar magnification ratios, don't we? It's t...
Well, I'm pretty sure that MFD of a zoom lens is the same for all of its focal lenghts. At least that's how it works for my kit. Regardless it's 18 or 55 mm, MFD will be always 0.25m, so the largest magnification I'll get at 55 mm.Taking things pract...
Right, sorry, I sometimes write things faster than I think. Thank you for your answers, I just checked the 80D's manual and it also has distortion correction And I'm aware that post-processing with a proper program will be better.
