Definitely not interchangeable on my K-1. Really too "bright" a screen to focus at all with super fast lenses (50/1.2, 100/1.8). The O-ME53 makes it possible, but not easy. Reality is focus confirmation or live view with focus peaking. Latter works really well with the large bright swiveling screen, but you're relying on IBIS when holding the camera away from your body.

Using a neckstrap and LCD at 90 degrees I have used Live View to achieve stable critical focus with 50/1.2, 85/1.8, 135/2.5, 200/2.5 lenses. Very, very effective for critical focus.

'Good enough' focus is actually very good optically, and excellent with focus confirmation beep on near-field subjects.

I tried manual focus with K-1 a couple of weeks ago with A*85 f/1.4 and A*135 f/1.8.

While it does take som training to get used to I did manage to focus without confirmation. The A50 f/1.2 was a little more difficult, probably because it is soft at f/1.2.

These two (second 100%crop) where with A*135mm.

Hi

I have swapped over the magnifier from my K-3 and it works very well for me.

It is one of those, but I can't remember exactly it was a long time ago when I bought it. I think it is the 1.6x one.

There is this one also:

But be careful with the greater than 1.6x sort as you may not see be able the borders in the VF

The thing is, they fit on the K-1, anyway mine did.

Cheers

Thanks for that extra info, I must admit that getting on just fine with the viewfinder and my manual focusing (with spectacles on).

So much so, I'm not even using my Pentax O-ME53 Viewfinder Loupe Magnifying Eyecups.
