As my K3 died recently (mainboard dead… repair would cost 400€) I have bought a used KP. I am using it only a about a week, but up to now I am very happy with the change.
Advantages of the KP:
- Better high ISO
- Better AF
- Wifi (for tethering without flue card)
- Tilting screen
Advantages of the K3
- Better grip and buttons (for my hands the bigger grip of the K3 is more comfortable, the AF button is harder to find on the KP). But I think I will get used to the KP.
- Bigger battery (no problem for me; Just bought 2 spare batteries)
- Stronger onboard flash (better high ISO of the KP compensates for this)
I would get the KP, without doubt.

It does not have an onboard flash. Very useful for macro in the fields…

Attached proof of lack of problems with onboard flash with K3, at 3 meters and at closest distance.

That's good to know. I did't know it is internal focus. Working distance is more important than minimal focussing distance. I am tempted with the Irix 150. Will be watching :-)

Yes, that is a good idea.
Thank you.

I just wanted to ask why CIF works with my K5, and did not with my K3.
Thank's for the answer.
I usually use only the AF button to focus.

Depends on your needs. For big insects the 300 + TC is a good option. But for smaller animals it's scale of 0,36 is not enough. And the working distance of the 100 frequently makes that you don't get the shot (animal flew away).
I normally use the F100 and the DA*300 for macro of insects, both almost always with the TC 1,4x. To have the option of scale of 1:1 with 150mm, and 1,4 with the TC added, is interesting for me.

Hi
I don't understand your experiment very well. The method that I propose is designed for mixed light, and the idea is to control the proportion of flash to ambient light. If you ensure that there is minimum impact of ambient light you are just using flash illumination, and your underexposure metering in M-Mode should be very big. If you just want flash illumination, this method is not especially useful. I prefer mixed illumination, to avoid dark backgrounds and harsh shadows.

Using a p-ttl flash in manual exposure mode is a different story: You control the proportion of flash to ambient light underexposing to a certain amount.
If you underexpose half a stop, the flash will complete the rest. In this case, you have mostly ambient light.
If you underexpose one stop, you will have about a 50% of ambient light, the rest the flash.
If you underexpose two stops, ambient light will be only about a 25%, 75% of flash light.
... and so on.
With cameras that allow exposure compensation in manual exposure mode, you have the possibility to change the sum of ambient and flash light that is used for exposure. This way, you have control not only over the proportion of flash/ambient light (by underexposing), but also to control total exposure level (with exposure compensation). With the K10 I could influence changing the flash compensation, but this had a smaller effect.
