Summary I just received this item in the mail today and started it up. Here's my quick summary positives:
(1) Good image quality.
(2) Works with larger, newer SDHC type cards like the 16 GB I have in it now.
(3) Does auto-rotate according to how it sits. In other words, if you want to look at photos in vertical orientation, load nothing but that type of photo on your card, insert it, turn the viewer to vertical orientation, and you will see them as you shot them. Same applies for horizontal / landscape orientation. You should load each type of photo on a separate SD card so as not to leave unused space.
(4) The 1.6 to 1 aspect ratio of this device is good for DSLR photos because it's the closest thing available to their 1.5 to 1 ratio.
(5) The length of time each photo is displayed during the slide show can be varied according to a selection of discreet settings including 3, 7, 20 sec., 1 min, 5 min., etc.
(6) Photo slideshow can be displayed in a randomized sequence, however, this feature does not include a memory of what has already been displayed. Given the basic laws of statistics, you will encounter a significant and noticeable number of repeats if you play the slideshow in random mode for very long.
For any given number of photos in the set, one can determine the length of a random slideshow such that there is a ~50% chance of every item being unique. For 100 photos, this number is 12; for 1000, it's 38; and for 10,000 it's 118. Bottom line: if you see repeats in the slideshow it's probably not because the unit is broken, but due to the laws of probability and statistics. More photos loaded means longer intervals without repeatition, but the length of those intervals does not increase in direct proportion to the number of photos you have loaded.
Aside from inadequate instructions in the printed manual that comes with the unit, I cannot think of any significant problems with this unit. Due to the lack of clear instructions, my initial rating was 3 stars. However, once I read the more complete, digital versions of the instructions, I realized this unit does meet all my needs and raised the rating to 4 stars.
Some minor issues: There is no contrast or color saturation setting on this unit. For color, there is a choice of monochrome, sepia, or color, and that's it. ( But before you will buy this digital photo frame I suggest you have to check for best deal before you buy it at: digitalsphotoframerefer.blogspot.com/2011/11/sony-dpf-d1010.html )
