comment How can I set a shutter speed slower than 30s on my Nikon D5200?
I am using the same device on my Pentaxes. I can recommend it. It functions both as a simple remote, as a time lapse timer for 1000s of images in a row and as a long exposure timer.

comment How can I import images from iPad into Capture One?
@ElendilTheTall - because he hasn't. Is it so hard to understand that other people have other preferences for their workflows? Or consider him having a small SD card, e.g. 8GB, but lots of memory on the iPad (64GB). So, the iPad can be used as a storage when the card gets full. Or he may have edited the imported images on the iPad with the Photo app. Lots of reasons.

comment What does fast/normal/slow mean for Pentax auto-iso?
@rfusca, yes, I assume a static object, like taking landscape shots when nearly dark. I'd like having an option to allow longer exposure times when SR is on - Pentax has a lot of similar customization options, and that's what I love Pentax for.

BTW, I've just documented a few related issues I've found with the K-3 on my crappy website: tempel.org/Photo/Photo#toc5

comment Pentax P-TTL: Why and when does underexposure occur and what can I do?
I have to say that your suggestion to use M mode for flash pictures was a totally new idea for me. I am surprised to see that the Camera is smart about limiting the exposure time to sync speed (1/180s) and then varies the amount of flash light as needed. Contrary to that, using other modes requires me to limit the auto ISO range because it tends to raise it too much too often. I think I will now set up one of my User modes for this purpose, in X mode.

And another thing: One would expect that activating Shake Reduction would have some effect on the minimum exposure time, but it doesn't. That's one thing that could need improvement. If only Pentax, uh, Ricoh, were more approachable...

comment What does fast/normal/slow mean for Pentax auto-iso?
A related question would be: How does this setting compare to the Program Line setting? I suppose that while we do have the "Program Line" setting to control how the P mode selects whether to keep the aperture open or closed as much as possible or keep the exposure time as short as possible, the ISO curve does a similar thing for the other modes (Av, Tv).

comment What does fast/normal/slow mean for Pentax auto-iso?
From my own testing, I get the impression that the rule is simply: "Slow" and "Fast" curves raises the ISO setting one LV step later or earlier compared to the "Normal" curve. Could be wrong, though, as I only tested with P mode so far. Feel free to prove my theory wrong :)

comment What does fast/normal/slow mean for Pentax auto-iso?
For your testing, keep 2 things in mind: 1. Set the Program line to Normal if you're P mode. 2. I do not believe the aperture affects the behavior directly. Instead, it decides on whether to raise ISO or instead lower exposure time or open the aperture when it has still room to work with the ISO value. So you need to adjust the lighting every time you switch a setting, then see at which point it rather changes ISO over the other parameters.

comment What's the difference between P mode vs. Av or Tv?
Yep, saw your question too late. But happy to see it still helps.
