Pentax K-1 and AF light

In dark environments aperature settings of f1.4 to f1.8 is needed to reduce the ISO to an acceptable value. In addition to that a shallow depth of field if mostly wanted for event photography to focus on the main moment which the photographer wants to capture. I guess hyperfocal distance is more related to landscape photography in which the focal length is small and the f number is huge...

I like modeling lights for portrait shootings, but for events I don't want to be the one who is memorized by the people as the guy with the bright light on his camera who ruined the atmosphere :-D

Thanks for checken that!


I'm glad to hear that the AF light is working fine at least on the Pentax ...FGII flashes. (The official Pentax site over here is excluding the K-1 and K-1 II in respect of the AF light)...


By the way, I read that the AF light is white? Is this annoying in dark environments? Is it a grid or how does the light looks like?

Paul, do you mean that the AF light of the Pentax AF360FGII is turned on later compared to the K-1 internal AF light?


Fortunately, the K-1 internal AF light is not turned off when Metz flashes are being used :-)


But when using the Cactus V6/V6II transmitters you are lost in the dark: the K-1 disables the internal AF light and the Cactus AF light is always on (annoying for the model) or you have to completely turn it off :-( Therefore I'm looking for an AF light device...

Hello,


I'm having some issues with the AF light of the K-1. In my opinion the AF light is NOT turned on fast enough (using AF-S mode of course): the camera first tries to focus and if this is not sucessful it turns on the AF light. I miss shots at weddings and portrait shootings in dark environments due to the slow focussing :-(


I tried to overcome this issue by using a

1. flash (Metz 58 AF-1)
2. Cactus V6 and V6II transmitter
3. Godox transmitter X Pro

But non of it actually solves the issue:

1. The AF light of the 58 AF-1 does not work with the K-1. I have installed the latest firmware, i.e. version 6.0.

2. I can only turn on the AF light of the Cactus transmitters at all(!) times instead of only during focussing.

3. AF light is turned on, but basically it is too late (similar to the internal K-1 AF light) and the light itself is not a huge benefit due to it's shape and intensity.


I have several questions:

Q1: Do you also have the feeling that the K-1 turns on the AF light too late?

Q2: Do you have the same issue with the Metz 58 AF-1?
Q3: Is there a P-TTL flash which AF light works with the K-1?


I'm also looking for a device (it does not need to be a flash; it might be an additional device) which turns on its AF light as soon as I start focussing (back button focussing is turned on).

Q4: Does anyone know if a device like this exists?

Q5: Is this possible from a technical point of view? Is the information that the camera is focussing being provided to e.g. the hot shoe?


Q5: Does anyone know how the AF light works without interfering with the camera's light metering? Is the AF light being turned on first for focussing and right before the image is taken it will be turned off and the light metering is performed?


Puh, many questions... ;-) But I hope you understand my problem!


Regards, Roland

FA31. Is it worth it. (Rant about LBA)

Sandy, thanks for the fast answer and great portraits!

I have the feeling that the FA31 is less sharp compared to the FA77...? I'm not sure... there are not many portraits wide open out there... But chromatic aberration seems to be on the same level as the FA77.

The Sigma 35mm is the sharpest of course, but I'm having huge issues with the AF above 10 feet :-( All the same with three copies :-( Maybe it's just my K-1...

Hello, I'm wondering how good the FA31 performance (sharpness and chromatic aberration) is wide open using the K-1? Does anyone have a comparison to the FA77? Thanks!
