K1 shutter not responsively in manual focus mode?

LFLee · 11-24-2019, 07:16 AM

Hi, attached a manual focus lens - Voigt 58 on my K1.
while in shooting session, it sometime not releasing shutter when pressed - I did check and see it is not busy writing data into SD card.
it's very frustrating to miss the moment I want to hit the shutter.

It shouldn't matter, but I did the following:
-changed the 'shutter release priority' in both Auto focus mode to "release priority" instead of "focus priority"
-switch to MF dial on the side of K1.

I am not even using LV.

Any idea? I haven't use Manual Focus lens for a while, did I missed to change some settings?

Thanks in Advance.

It is possible you have "Catch-In Focus" enabled, check your menus. Going from memory, once selected, this feature is enabled if using a manual lens but the focusing lever is still set to AF. Setting the lever to Manual should allow you to activate the shutter whenever you press the button

This is a very useful feature, IMO, but frustrating if you are not focusing fast enough to satisfy the camera's assessment of "in focus".

I can't say if the following holds for the K-1 with MF lenses. On my K10D when the camera is switched to MF the shutter will release without focus confirmation indicated (beep and hexagon symbol steady in viewfinder). In AF-S the shutter will only release with steady focus confirmation (beep and steady hex). Depending on the lens it is very difficult to get a steady "lock" as the slightest movement of the lens or focus ring will cause the camera to try reacquire focus confirmation (beep-beep-beep and hex flashing). Either practice to get a steadier hand, set the camera to MF and use your eye to focus, use catch-in-focus. You can also set one of the buttons to turn off AF while pressing the button. I use this for those vexing times when I can't seem to get a steady focus confirmation - faster than fumbling around to find the MF-AF switch.

The K1 is exactly the same. The OP is putting the camera into MF so it should work as you say....interesting conundrum.

Using electric shutter and flash by chance? I came across some quirky behaviour that required me to disable electronic shutter to overcome. I can
not recall specifics but that solved it.

The OP says he is not using LV so won't be using ES.

The ES mode and flash are mutually exclusive at all times.

Thank you !

I did have Catch in Focus enabled and likely bump the AF/MF switch to AF. I will do some verification - but searching for Catch In Focus function on K1 help me understand where my issue likely come from.

Much appreciate!

Again, big thank you to everyone who response and help diagnose my issue.

Good to hear that was the issue and that you have it sorted!

This took me a little while to understand and get right when I first purchased my K-1. One follow up question though, is the Catch In Focus supposed to also work with AF lenses when the switch is set to MF?

The answer to your question depends on which AF/MF switch you are talking about.

If you mean the one on the camera, then no that will not work.

If you mean the one on some AF lenses, then yes CIF does work. Put the lens switch to MF, the camera switch to AF , and you are set.

If you are shooting in Single Shot mode what you may be experiencing is Early Shutter Penalty as described in the Performance section of Imaging-Resources K-1MKII review.

This is a major problem shooting the K-1 in Single-Shot mode.

I have been using the K1 since 2016 and have never encountered this once. Are there any threads on the issue ?

I encounter this every time I use my K-1 in Single Shot mode since 2016 when I bought it.

Odd. I also have been using K-1 or K-1ii since 2016 and have never encountered the problem. That does not mean it doesn't happen but saying it is a major problem when only a few people have noticed it is a bit of an exaggeration.

It's not odd. The K-1 suffers from the Early Shutter Penalty when shooting in Single Shot mode. I noticed this the first time I used the K-1 back in 2016. And it is a major problem for the K-1 in Single shot mode because it results in missed images. It happens whenever I use the K-1. Just because people haven't noticed it doesn't mean they haven't experienced it. Most likely they are not even aware of this problem in Single Shot mode.

The reason I brought it up to the OP is what they described sounds exactly like the Early Shutter Penalty problem in Single Shot mode.
