  • When the L-Mount system exists and the adaptors, it would seem like SA mount and EF mount versions of the same Sigma lens would have similar resale value since you could use either with an adaptor ...
  • iCloud Drive works pretty well as it uses WiFi. I have not tried SD readers on the iPad yet, but I think they would probably work a lot better now since I imagine you could copy files from the SD ...
  • New laptops are expensive but you can probably use whatever you buy for several years so it ends up not being too bad spread out over time... that can help justify whatever you are paying for it. I ...
  • If you think about it, the greater your resolution the more you can crop down to the higher quality center results of various lenses, so it expands the range of lenses you can use (well at least ...
  • Replied in Enjoy
    You may want to shrink down the size of the focus point if you've not done so already, I find it helps control exactly where it's focused a little more. That's the only advice I can think of ...
  • I think Sigma will have the cheaper offering and for sure they will want to be competitive in the space, therefore Sigma will charge around $2k or so... People are basing a hypothetical price ...
  • I think that is a reason I tend to gravitate to longer lenses - even the DP3M is not that long a lens but it's longer than an iPhone (which I also shoot some things with). The DP2M you have already ...
  • It isn't but with the EF mount to L converter it would be exactly the Foveon camera you could buy and use while still using your existing Canon system so the effect is the same as if Sigma had ...
  • Replied in For me, the DP3M
    The DP3M was I think about the most perfect Merrill that was - even with a bit longer lens, still compact, and probably the best lens quality of just about anything. I know you asked for one, but ...
  • It still holds true for the Quattro sensor since no wavelengths are ever filtered from capture, the top layer just measures light around blue wavelengths to a finer degree than the bottom two layers.
  • If there are so few highlight recovery pixels how could it have such a uniform effect around the edges of details? That looks way more like a sharpening artifact to me, along with the effects of ...
  • Replied in Using a Platypod
    One thing I've been using recently is a Platypod. It's basically a very solid steel plate, with adjustable feet you can optionally attach to the bottom for leveling, and slots in the plate you can ...
  • That was pretty nice, and one bit of information I had somehow missed - that Sigma will make SA to L mount converters, but also Canon EF to L mount converters... so we could get a Sigma camera and ...
  • Across most of the water I see what looks like kind of randomized purple splashes of noise, I would be interested to know what an SPP converted version looked like with color noise reduction left on.
  • Nice results, are there any particular lenses that led you to switch mounts?
  • Not quite sure what could be going on, do you have a PhotoPro app to run or do you not even get that after you open the DMG file that is downloaded? Four seconds doesn't seem to unreasonable for ...
  • Very nice, just one image seems a little odd in the set - the woman in the upper left corner of the water running through the sand?  It doesn't have the look of a long exposure... or at least not ...
  • SPP only changes settings in the raw file itself, it doesn’t use sidecar files for edits - it also has a separate ability to save a set of edits from a photo that you can stamp  on any other, ...
  • My workflow so far has been to load X3F + jpg files onto an external drive with built in WiFi, connect the iPad Pro to that, then transfer select jpg images to the iPad for editing in Affinity ...
  • Replied in Works so far
    I have not used it interactively much yet but I bulk converted a bunch of images just recently and it worked well.  Mojave is more of a speed and stability release so it’s bound to be more stable ...
