Its RKM's recent activity

  • 6D for £856.95 with 7 apparently in stock at that price! http://www.simplyelectronics.net/mainproduct.php?pid=21467&sd=bund I used to buy a lot of computer gear from a company called Simply ...
  • Hi Gordon, it may be worth checking that the flash is showing ETTL in the panel and not just TTL, which would result in the effect you describe.  ETTL uses the pre-flash to work out the exposure, ...
  • It isn't the ambient temperature that does the damage, but the temperature that the polarizing layer in the EVF reaches when the sunlight, or rather the near infra-red content of the sunlight, is ...
  • There were reports on here about a similar issue on the EM-10, so it isn't unique. What is more concerning is that a browse of Epson's LCD history - on their own website - shows that they openly ...
  • Many reasons, not least of which is the significant difference between "simple" and "economic".  Changing a production line to use different glass thickness is simple, but it isn't cheap to ...
  • Of course it is possible to have both - and this certainly is a design flaw, in the classic sense. Quite simply, it is the upper polarizing layer of the Epson LCD panel which is being burned by the ...
  • In may case, and that of many others aged 50+, its the opposite problem.  Distance vision is perfect, so no need for glasses when viewing scenes.  However, presbyopia sets in for everyone after ...
  • That would be around -1 diopters, which seems to be quite safe. One problem is that as you get older, presbyopia sets in and you need to dial up a higher dioptre correction for a sharp image, or ...
  • Olympus say that the nominal dioptre range is -4 to +2. and the camera has 14 clicks to cover the full range. That works out at just under 0.5 dioptres per click. So if you are 5 clicks down from ...
  • And??? I suggest you ask him what dioptre setting he uses.  That makes a huge difference in the vulnerability of the EVF.  If you use the eyepiece it close to the maximum dioptre setting (or use an ...
  • With ETTL (and ETTL-II) the flash exposure is computed in the camera, not the flash unit. The flash is just a "dumb" unit which flashes when, and for how long, the camera tells it to. The only ...
  • Those settings should be OK on most situations, but just how high are the ceilings you are bouncing off?  Check that the flash exposure confirmation is lighting after each shot as it may be just ...
  • I am sure you recall this image, and many similar others, from the great 5DII banding debates: Banding is just one form of PRNU. Just to be clear, this is not my image, and I am not plagiarising ...
  • Dicky, is your PC connected to the Internet through a wireless router?  I can see how what you describe works with a wired Internet connection, but would like to know more about your setup if your ...
  • Created discussions EM-1 WiFi question
    I have been using the EM-1 WiFi connection for a while now, either with a smartphone or my PC/laptop using either the standard web browser or the free( ! ) Camera Control app by Andreas Rebs ...
  • What domain is shutter speed, or exposure time, in? Moving filters works fine with static scenes, but get some movement during the exposure and the rainbow effect jumps out - time domain moire, ...
  • Since every single digit OM camera since the OM-1 was introduced in 1972 has had the switch in the same place, more or less, I can assure you it isn't a problem. Now, if only Olympus had put a ...
  • Not all 3D horizontals are level when projected onto a 2D plane - many, especially closer, horizontals naturally appear tilted. The water level is horizontal but, viewed out of its plane and with ...
  • Skipped lines in video are trivial to verify from the vertical moire it creates.  Just point the camera at fine gratings, such as a picket fence, and rotate it.  If the moire is significantly ...
  • The 550EX certainly is an ETTL-II compatible flash and works very well with the 5D3 in conventional automatic and high speed modes.  Differences between ETTL and ETTL-II are independent of the ...
