  • I would suggest that you start with one unit, and dial it down so that your subject is properly exposed at f/5.6 or f/8. Then put the second flash behind the subject to illuminate the background...
  • But it is true in some non-technical way? Here is a quote from the message that we have received: "GearShop is a unique photo specialty store that utilizes DPReview's comprehensive testing and...
  • We have plenty of examples in this forum of marvelous portraits and landscapes. If you have in mind DOF control, then I would not call it "better portraits", it's just one specific style of...
  • The first thing that comes to my mind is the aperture setting. Your image was taken at f/16. Very narrow apertures cause image softness due to light diffraction. You can take a look at the lens...
  • The question is not whether we have to wade through it or not. The question is whether the outcome of a review, or even whether an item is reviewed or not, will be colored by the commercial...
  • Banding has been observer with only one lens: Panasonic 20mm f.1.7. It occurs at ISO above 3200, and not every time. Overall in the real use this issue is encountered only rarely, and users...
  • That sounds like the "looney 11" rule. In that case the shutter speed is not a fixed value, but is equal to 1/ISO, so for ISO 200 the shutter speed would be 1/200. At the same time, the EC...
  • Panasonic gets soft after 200-250mm, and at 300mm it shows a fair amount of coma. For web-sized images it works fine, but at large magnifcations you will see that stars look like little fans. Vlad
  • On Olympus cameras it is possible to select Auto ISO in the M mode, in which case the camera will try to select the ISO to achieve a proper exposure, but it will not raise the ISO above the limit...
  • Replied in Any examples?
    It seems that every poster interprets your question differently. Could you post any examples of what you are describing?  Thanks- Vlad
  • With all respect, pulling the "free content" card is totally unfair to the users of this site. To be clear, I disagree with morepix's demand for advertising-free content, whoch is simply...
  • I use Cactus AF50 on E-M5, it functions properly – TTL, high speed FP sync, etc... First I would try to wiggle the flash in the hot shoe to make sure it's seated and locked properly. If that...
  • I honestly dislike this one. I think the OOF area sets off too quickly, and makes an impression of the food floating in some white muck. The attention is focused on some grains of rice and a slice...
  • Replied in Photosig
    http://www.photosig.com/  offers a place for critique, and also has forums dedicated to discussing  images, photographers, and technique. Vlad
  • Replied in No, you don't
    Even when the recipient's signature is required, it does not have to be you personally. In my experience FedEx, UPS, and USPS will accept the signature of any person at the residence. Furthermore,...
  • DPReview gives a particular endorsement to the Gearshop by allowing to use its name and logo. This is different from a link to an independent merchant, that relies on its own reputation, and makes...
  • Do you think that getting into the business of selling the gear will cast suspicion on the objectivity of their reviews, or is it ok the be a reviewer and a merchant at the same time? Vlad
  • Replied in Consider G3
    Consider getting a Panasonic G3. Although 2 generations old, it is still a great camera, and in my opinion the high ISO performance is quite competitive with E-M5. Size-wise it is very close;...
  • Replied in Why E-M5?
    What are the advantages of E-M5 in your view over the other µ4/3 cameras? What do you expect to see in E-M6 that would be worth waiting for? Putting these thoughts down will help to understand two...
