Enjoying new TT350 that came today

Another happy customer. I can confirm that the TT350P works on the K-3 as well, even though Godox doesn't list it amongst the compatible models.

One thing I really like is that the TT350P can do HSS in manual mode. Not even my Metz 58 AF-1 can do that (HSS only works in PTTL mode). That's potentially very useful for fill flash for birds, because setting the shutter at the maximum sync speed (1/180th on the K-3) is often too slow for wildlife. With the Metz in PTTL/HSS, I've often found the bird moves while the flash is metering for PTTL. With the TT350P in manual mode HSS, there doesn't seem to be any lag. Of course manual setting involves guessing the appropriate power level - there's such a fall-off with HSS that the power output has to go up a lot as the distance to subject increases. But I think with practice I'll be able to guess the setting better.

If Godox does a higher-output PTTL flash (e.g. TT685, with GN 60) with the same features as the TT350, I'd be looking to get one to replace my Metz.

I guess my only other suggestion/question is - is your GRII up-to-date on firmware (ver 3.01 or thearabouts I think it is...)?
Hopefully someone else has thoughts. I'm empty.

Having never bothered with DCU beyond a cursory poke-around several years ago, I can't answer definitely but... DCU is a Pentax specific product and if I had to guess, what you're experiencing is likely just the result of a difference in RAW files and cameras. DCU can emulate all the in-camera JPG tweaks available to a Pentax camera for which is was made. I imagine when working with Ricoh GR files it is likely simply showing you the untouched RAW file without changes.

I assume you're shooting RAW+ and expecting in-camera color/effect setting to show up in DCU, yes? Hopefully someone else here can provide a better answer.
Do you have the most recent update for DCU-5 applied to your installation?? If you look through the change-log of updates, it seems quite a bit was added over time for GRII....

(Personally I do all editing/processing within Lightroom only these days, and only occasionally use JPGs for reference and ballparking the shot whilst shooting unless I'm using them for exclusively which I still do quite a bit.)

Did you see JPEG files in the card if you view the content on computer directly? Lightroom imports raw only if JPG files are in the same location.

This sounds like it could be an issue with Lightroom. When shooting in RAW+, are you seeing both formats when accessing the card directly?

Question about bracketing

Yup, use Av mode to fix the aperture and Tv mode to fix the shutter speed.

You can set it up so that only shutter speed changes when bracketing in M exposure mode. It is done like this:

Menu Button Customization
E-Dial programming
Second tab
M exposure mode, set green button mode to Tv shift

Sigma 28 1.8 macro vs. 31 limited on K 1

You can't go wrong with the 31. The higher cost is definitely worth it.

Although it seems like you are leaning towards the 31, I thought I'd post these taken with the Sigma 28/1.8 EX DG. Not on a K-1 but it may still help you with your decision.

FYI, although the Sigma is a 1.8 it registers in the camera as 1.7. That was the case on a K-50 and K-S2.

Shot RAW on K-S2 no PP.

Sigma 28 1.8 macro vs. 31 limited on K 1

The Sigma has very good close focusing abilities. It is not a true "1:1" macro, but it is a lot more versatile than the FA 31/1.8.

On the other hand, the FA 31/1.8 is a lot more compact, beautifully built, and has an unrivalled out-of-focus rendering.

I have both but haven't tried the Sigma 28/1.8 on FF yet.

I've seen that photozone complains about the extreme borders but Klaus also reports a nervous bokeh and a wobbling inner lens tube. I have never experienced either of these problems. I wonder whether Klaus' copy was OK.

Forget about the f1.8 Sigmas.
Yes, that means the 20, 24, 28mms.

They are not good on the edges (esp on FF) even stopped down.

The FA31ltd on the other hand is excellent.

Embedded Profiles in K1 DNG's
Posted By JensE

The DNG embedded profile translates the raw sensor readings for the various colors into standard color space coordinates (I would have to look up which one). I.e. it describes the color filter (Bayer matrix) characteristics and sensitivity of the sensor behind that. Besides the color mix via a matrix, it can also employ some non-linerar response curves via lookup tables, impacting the contrast. I think the embedded profile is a simple matrix profile mapping the colors 'faithfully' ('right' translation is subject to your definition of 'optimal') but not impacting contrast. Lightroom has some alternative input profiles, efficiently doing some pre-processing already. Other, like the commercial Huelight ones, apply again different criteria resulting in different color rendition, subjectively more pleasing at least for some people. The input curves are the main ingredient to the color signature which often are mentioned when people compare raw development software.
