About me:

I've been shooting digital photography since the beginning, starting with the Canon RC-250 in 1990 and advancing to the Chinon in 1992, then to the Ricoh RDC-1 in 1993. Since then, I have had a succession of more conventional digitial cameras including models from Nikon, Minolta, Ricoh, and Casio. In 2002 I used Nikon D100 and Minolta D7i.
Prior to 1990 I was a film photogrpapher, starting with 5x7 and 4x5 view cameras in the late 1940s, adapting to 35mm in the 50s (Konica, Leica CL), and experimenting with 120/220mm format using Rollei TLR, Mamiya 120, and Mamiya 645 systems. I used to do all my own wet chemistry using Omega D2 and a color darkroom. But in recent years switched to scanning and digital printing. Since 2007 I have been concentrating on large landscape prints using Hasselblad H series cameras and backs, and since 2013 36mp Nikon and Sony cameras. Currently using D800e, A7r, and RX10. My largest print is 30" x 96" using a Fuji 6x17 camera, Fuji Velvia 100 and an Epson 9000 scan. Medium format digital cameras can reach this quality, as can D800e/A7r with stitching. I also have the RX10 for outdoor fill flash purposes exploiting its ability to sync up to 1/4000th which smokes Hasselblad which is limited to 1/800th sync, and the slow DSLR cameras at 1/250th. I have also been working with longer lenses and find the Nikon 800mm f5.6 with 1.25x extender lens gets its best results using A7r, not 800e. The difference seems to be A7r's superior live view which facilitates critical focussing.

    Dear Xizang, Thank you for your thoughtful response about "Choice". I agree with much of what you are saying, and in fact for that reason carried Sony 28mm FE, Sony 55mm FE, and Zeiss Batis 85mm ...
  • Replied in Sony 24-240mm
    I just got back from a 30,000 mile trip starting in Cape Town South Africa and ending in Tokyo. I visited 16 countries over 38 days and took tours in most of them. I carried a batch of prime ...
  • Here is your example photo with CA removed in Lightroom. The 55mm produces a lot of chromatic aberration when wide open, especially in out of focus regions. Image processed in Lightroom to romove ...
  • Commented on article Sony Alpha 7R II Review

    Congratulations to the dpreview staff and Rishi for this excellent review. This is the best ever of this site, and covers many complex technical points against a background of noise from "internet...

  • Replied in P900 or P610?
    P610 has an excellent macro mode which focuses to a few inches. I use this all the time for product pictures for eBay. I assume the P900 has the same. You get this mode by pushing the selector ...
  • Its hard to understand why anyone would take the time to post such ugly shots on dpreview and then expect anyone to listen to his opinion about the lens!
  • Actually f6.5 at 2000mm eq is perhaps a sweet spot.  The f6.5 and 1/2.3 gives enough depth of field so that focus at 2000mm is feasible.  Have you ever tried to focus a 1000+ full frame lens?-- a ...
  • Replied in P900 for birds
    FZ1000 is a great travel camera. Usually when you need f2.8 you are inside and can use f2.8 where you are shooting wide anyway. Telephoto is often outside where the slower aperture is okay during ...
  • Batis 85mm doing great here! Inyoung at Baker Beach San Francisco at f2.2 for subject isolation. Photo is cropped about 30% Full-size OOC jpg of the GG Bridge. 85mm at f8 for DOF
  • Replied in 20 x 30 inches
    I use Costco's fantastic 20x30 inches print service for everything. If I get something that looks good, and people like it, then I print at 30 x 40 or 30 x 45 and frame.
  • I have those three lenses and the 28mm f2 is a great lens, it gives up nothing to the other choices in this range, and the 21mm add-on option is good.  I also have the Rokinon 14mm lens in Nikon ...
  • Dear MissingLinkie, Fantastic that you have found a way to get ttl to work for you. Could you explain a bit more? For example are you using ttl with S, A, or P mode (each uses a different algortihm ...
  • Ok, so I went to the store and this is what happened.  They told me they had just sold their demo G3X a few hours ago, and it was impossible to keep them in stock because demand was so high. So I ...
  • Ken Rockwell's opinions reflect his own personal view of photography, and should be read by folks who subscribe to similar views. Here are the main points: 1. He believes the image should be fully ...
  • Kharan,  Thank for clarifying that you didn't actually test this camera.  Howard S says he tried a "dumb trigger" and it didn't work. Maybe the way to confirm that Canon has really crippled this ...
  • Kharan, I completely agree with you about "Forget TTL" and use "dumb manual flash".  However, people in this thread are implying that they tried this and it doesn't work on the Canon G3X.  Your ...
  • If flash sync at 1/2000 doesn't work with external flash then this is a huge problem.  The main (only?) reason for buying a camera like this is to get the leaf shutter and high sync speed.  This ...
  • Replied in More choices?
    Just a small correction, this is not a 1 kilo lens, the actual weight is 0.78 kg, which is not an unusual weight for a full frame zoom lens.  Further most of the weight is near the base (camera ...
  • I had this and used it with the Contax 35-50-70 zoom and the 90mm.  When it worked it was great, but it would intermittantly develop problems and require fiddling.  I suspected the gold contacts ...
  • I found the Tamron SP 17-35mm f2.8-4 to be an excellent lens.  It sells for about $250 on eBay and weighs about a pound.  I have the A-mount version and use it with the LA-EA4 adapter.  I found it ...
