  • Where there's a large contrast (deep shade with shafts of bright sunlight, I've found the metering to not be good enough to guarantee success. Either shoot manual or use the EV and the ...
  • I've got a good friend who shoots Canon (with good glass). When we do portraiture or landscape, my stuff looks noticeably better than his, especially in print. And so, for me---the advantages of ...
  • Professionals need 'good enough' quality, and Nikon and Canon (and Fuji and others) can offer that. Professionals who make a lot of money on their work are good businessmen (and women)---they may ...
  • Hey! The jpgs are good, but I'd shoot RAW + JPG That's not my workflow, but if you have a group of similar shots, the batch TIFF production in SPP and then finishing in another program is a good ...
  • Hi Mike, Going back through the archives, here's something from the early days of my SD10---November of 2004. The SD10 files were a delight to work with in most cases. I have a bunch of stuff ...
  • Replied in SD9 China 2004
    Mike, Indeed—this is an excellent set of images and a fascinating story! You weren't the only one working up old images this weekend. I spent some time going over some 2005 SD10 images of the ...
  • I haven't looked in detail, but I will say that I can see the Quattro is more demanding of lenses and focus. A decentered lens will show this type of issue---it was very clear with one of the 'big ...
  • Well, the same discussion was had with the SD1M versus the DPxM---the DP series generally had 'better' image quality because the pairing of an excellent lens with a fixed and optimized optical ...
  • Replied in SD Q Freezing
    Have you updated the firmware? The other suggestion I'd make is to switch the finder view to one or the other (based on your preference) rather than auto. I've had one lockup since doing the ...
  • Hi Oz, With regard to the review (Eugene's)---he's had a pretty long history of bashing Sigma cameras---in fact, when I clicked on the link my first response was 'is he still doing this?'. So, I'm ...
  • Tom, I will admit that this didn't make sense to me, but I googled it and now it does (spherical aberration causing the effect). Thank you for edumacating me today! :-) My snide reply would be 'buy ...
  • Replied in Yes, me too...
    Tom, I got my first splotch on frame 200 or so, and a second one shortly after (I've shot about 500 frames). Sigma USA will clean the sensor for you (this isn't a dust protector issue for those ...
  • Hi Mark, I'll try to pull something together for you in the next couple days. You know, in some ways the easiest files to process for me were the SD10s. The color was easier to get good than the ...
  • Like rape? Really? See if you could have a moderator change this to a more appropriate analogy.
  • Hi Mark I have the SD15, and I have not had issues with my sd Quattro blowing highlights yet. So far (early days---a few hundred frames), it's much, much better. I'm not sure I have any fantastic ...
  • John, I shot the sd Q for a week in Florida, and never saw it overheat (hooray). On the other hand, it threw two shutter boogers on the sensor in about 400 frames (it started with 0). I hope that's ...
  • Woo hoo---I love being an outlier. The good news is that the overall time is about 6 s per shot, so that's not horrible.
  • I'll play, although it doesn't appear to be fun for me... SanDisk Ultra 128GB microSDXC UHS-I Card with Adapter, Black, Standard Packaging (SDSQUNC-128G-GN6MA) (From Amazon); Class 10, 80 Mb/s 17 ...
  • I've shot with the camera for a week---on vacation, with no ability to pixel peep. The camera itself is a very nice step up from the SD15 I was shooting previously. I would suggest ordering it ...
  • Very nice. In my limited work, colors are very good. I am reminded how 'cool' my old 70-200 is, but I was pleasantly surprised that AF worked.
