  • Thank you for your suggestion. As I said: "she saw someone using a Nikon/Canon/Sony 70-200mm F2.8 lens in her photo group, she asked me to get some lens like that for her." 'she saw someone using' ...
  • Reading many posts about the possible coming of a new Pentax 70-200mm f2.8 lens, I would like to get some suggestions and answers for a question from my sister. She has a Kx, and I bought a Pentax ...
  • The size of Filter thread? 52mm, 58mm, 62mm, 67mm, 72mm, ...? If it is larger than 62mm, it cannot be very small. The Nikon 16-85mm F/3.5-5.6G lens has Filter thread 67mm. Did Pentax copy or ...
  • I am very interested in this "small and light weight size" 16-85mm lens. It could fit the KS1 very well, as well as a thin-box type of K-mount mirrorless body. when I took my K01 + 18-135mm out, ...

  • Sorry for updating so late. I forgot my passwd to login DPREVIEW, when I was out for a week. :-( My K5-IIs seems be back fine. I cannot tell what has made it normal again. I only did the following: ...
  • Tab #2? I had set LCD Display Settings with Brightness -3, Contrast +3. I noticed that the GrayRGB color chart on LCD Display Settings screen is very bright, before I set the new values. Now, I am ...
  • I usually shoot with M mode by setting the exposure according to the position of EV bar in OVF. And I used to having the EV bar at -1 (under exposure), and Auto EV Compensation OFF. Everything was ...
  • The price seems to be very attractive! I would like to know how long the X Vario would take, after taking a full-size 16mp RAW photo, to write it on SD card? Some of these 16mp cameras have very slow ...
  • Should have more colors for girls. :-)
  • It seems to have the similar problem to my (K01 & 18-135) combination. Although I could set the iso=3200 to shoot in museum w/o problems, I have to wait for >2s to write a 16m raw image, if ...
  • The combination of K5IIs +18-135 is good for shooting in theaters also. I have tested it. But, of cause, 16-50 or 50-135 is better, only if I don't have to change lenses. I guess MX-1 would not be ...
  • Unless Pentax/Ricoh can really sell this new XG-1 , I don't see the point to release a X-5 update. Pentax/Ricoh is doing well on selling the MX-1 , so an updating version of MX-2 , or K-02 , has ...
  • Thank you for your inputs. My only concern for Dell's monitor is their Q.C. It is very often that people would run into a bad one, then send it back for replacement. But, Dell's customer service ...
  • Yes, I am reading and studying the websites to find a color-accurate and price-affordable monitor. Thank you for your replying. Actually, http://www.tftcentral.co.uk/ is one of my favorite website ...
  • Many Thanks! My pentax k-01 and k5-iis both have AEL. :-)
  • I shoot all my photos with RAW, then convert them in Lightroom or Photoshop into 16bit tiff files embedded with aRGB profile. I would convert them again according to usage. I did try once to send ...
  • For me, the Asus VE258Q's problem is not with sRGB. From the tech specifications and user reviews, it is an excellent monitor. But, it is not customer calibrate-able. iMac is accurate or not, that ...
  • I have a similar question. If my camera is stabilized at a location, and the time range I am shooting is about 1-2 hours. The outdoor lighting is changing all the time. Can I use P mode to keep the ...
  • I am searching for a True Color monitor under $500. It seems that Asus PA249Q fits my options well: true color (3x8bit for 24bit), 1900x1200, under $500. There are other 3 monitors, Dell U2413, ...
