Viewfinder magnifying eyecups for Pentax DSLRs: DK-21M and O-ME53

I've owned two Pentax DSLRs (*ist Ds and K10D). For a crop sensor camera, they have good pentaprism viewfinders with 0.95x magnification (50mm lens). But I still wanted to increase the viewfinder magnification, especially since I use manual focus lenses a lot.

First I bought the Nikon DK-21M magnifier (1.17x). It almost fits Pentax DSLRs, but it is a bit tight to put on.

But then I found the original Pentax O-ME53 magnifier (1.2x), which fits better. And gives a better image.

Then I switched to Samsung mirrorless cameras in 2010, and the Pentax cameras were sold: the *ist Ds in 2012, the K10D in 2013.

The magnifying eyecups remained unused for a long time, but in 2020-2021 I sold them too, as I had no plans to go back to Pentax DSLRs.
