His is the 4th person to report the freezing issue with the sdQ here on the forums. And it does seem to be fixed with a firmware update.

I'm still waiting on the DP4 Merrill. You know, the one with the 80mm f/2.8 macro lens. I seem to recall Sigma announcing it. Or maybe that was just a dream. :-)

Yes, excellent photos. I have not  had any freezes since the 1.01 update. Since updating to 1.0.2 I have not had the temperature warnings, either, and focus speed is definitely improved with my ...

What was the EV range of this scene? Doesn't look very large to me.

I have focus issues with the 50-100 on the sdQ. Unfortunately, it's consistently inconsistent, thus difficult to troubleshoot.

Sorry, but when I had my Fuji X-E1 its autofocus was not only extremely accurate, it was also extremely fast. That camera is now 4 years old and is superior to the sdQ and any lens you can put on ...

A few shots from today using the Pentax SMC Takumar 100mm f/4 macro. Most of these were shot around f/8 but a few were at f/5.6. Lovely lens on this camera. A bit of a color issue like the 35mm ...

Similar to my 35mm f/2 Super Takumar, my 135mm f/2.8 also has some strange exposure issues occurring. These are with the 135mm f/2.5. Camera was set to aperture priority and this series of images ...

Shot a few of my M42 Super Takumars today and have some strange exposure issues occurring. These are with the 35mm f/2 that has the 49mm filter threads. Camera was set to aperture priority and ...

Blown highlights poor greens dead dog slow as cold molasses SPP slow autofocus

Mine is terrible. I consider it a manual-focus only lens now (except on the SD15). 17-50 is just ok. 10-20 f/3.5-4.5 is also ok. Neither is great.

I've been too busy to set up my studio lights but hope to this weekend.

You've experienced the same as me, but with the 50-100mm. Can you post an image with the CA? I haven't used the SFD mode nor do I plan to. I'll be keeping mine, though.

My MacBook Air has a dual-core Haswell processor that has onboard HD5000 gpu. This has 40 execution units, which means offloading to the gpu is going to be many times faster than running it ...

The two times it happened to me appeared to be random. Required me to turn off the camera and remove the battery.

SPP is dead-dog slow on my 12 core/24 threaded Xenon Mac Pro with 128 GB of RAM. So, my advice is, if you must run SPP get the fastest clock speed i7 you can buy and make sure you have at least 16 ...

The tire is sharp. The girl's face (focus point) is not. This isn't a tripod issue.

"My way" is the best way for me. Simply import the 16-bit TIFFs into Aperture then review them, which is very quick. If possible, make edits for the selected images. This, too, is very quick ...

But how do you get them into Aperture in the first place? It won't import the x3f files. Any speed increase has been slightly incremental. If they want to really make it fast, then they need to ...
