This might be old news to seasoned K-1 owners, but one of the first things I tried when my new-to-me K-1 arrived today was to test catch-in-focus combined with back-button focus. And joy of joys, finally I have on-demand CIF again!

As long as I keep the AF button depressed the shutter will not fire unless I get focus confirmation. Let go of the AF button, and the shutter fires regardless of focus or not. So no more need to dedicate a user mode for CIF

I think I like this camera

That is cool! I am surprised that it took this long for someone to discover the subtle change to the back button AF behavior.

I've been doing that all along but it never occurred to me to post about it

**brightseal** · 08-15-2017, 08:14 PM

Does this feature work with any lens?

ya seriously, I had to switch to back button cancel instead of back button af. I'm used to it now though.

Yes, quite annoying. Especially since it does work with the K-5.

Indeed! I was really happy to see that they have fixed this issue on the K-1. It really makes it much more enjoyable, for me at least, to shoot manual lenses.

No, only manual focus lenses. And any AF lens that has an AF/MF switch, I suppose, although I don't think I have tried that.

Never occurred to me that doing it "backwards" would work. Interesting. Oh well, I now have a camera that works properly again

**Rondec** · 08-16-2017, 02:25 AM

Congrats on the new camera. I'm looking forward to the shots you post with it.

08amczb · 08-16-2017, 03:05 AM

It works on the KP also, I use it regularly.

Thanks! I hope to get around to taking some images soon. Starting in a new job doesn't leave much time... But then the new job was my excuse for buying the K-1, so I shouldn't complain

Good to hear. It seems the K-3 is the odd one out, then. Just too bad Ricoh never got around to fix the issue there.

There's an additional benefit of doing it backwards. I don't have to teach whoever I hand the camera to that AF is a separate button. A lot of times the picture came out blurry cuz of it in the past.

Now if only we could select the focus point....

Not true about working with any AF lens with M switch, have had to put an extension tube between camera and lens with Siga 50-150 and Tamron SP Di 90mm f2.8 macro. Have had to do that with other Sigma lenses as well. Did see something once on blanking out the Data pin with tape would get round doing what i do but not sure which pin that is.

Ok, thanks for testing it - I never have. The way I shoot I haven't really found a use case for it. When AF does the work I see no need to switch to MF, and if AF fails to do the work it wouldn't make sense to switch to MF and still rely on the AF sensor. I'm not very good at manual focusing without visual aids (like a split screen), so CIFis my crutch when I "have to" use a MF lens and struggle with nailing the focus. Or, if I'm useing a tripod, I use live view with magnification to make focusing easier.

We're lucky to have a lot of options to choose from
