Hi,

I originally got them from eBay seller "ciecio7", who is based in Poland and the adapter quality was pretty good.

I replaced them with the Novoflex adapters, as their K-mount adapter has a control ring for the aperture so you you use it with DA lenses link.

Voigtlander also do K -> m4/3 adapter link

I would avoid cheap adapters - I bought one and had to return it because it wouldn't focus to infinity

HTH,

I used the K7 and Live View to focus and avoid mirror vibration. Exposure was 1/80th at ISO 320.

I also left the camera and lens outside for an hour beforehand to reach ambient temperature. If I don't do this, I can see the focus changing as everything cools down.

In my experience, the key to get a good moonshot is:

1/ Reducing the movement of the camera and lens.
2/ Choosing a night where the air is clear, cold and still.
3/ Shooting the moon when it's still fairly high in the sky.

Kris, cameras in which the flash housing protrudes a long way forward may have trouble mounting on the MTO, but I haven't found that a problem

Thanks for the kind comments

In terms of size it's not that big, the close-up angle I shot it from and the lack of visible camera body probably makes it look bigger than it is in reality

The main problem with it is it's slow to focus, so best kept for non-moving subjects. I have used it for bird shots though (when they're perched in a predictable position).

BTW, Does anyone else echo Mhuni's view that I shouldn't have cropped off part of the dark side of the moon?

Thanks,
R

Here's a shot of the recent new moon taken with my Russian MTO 11CA, which is a 1000mm F10 mirror lens:




Here's the lens itself. It was used by the military and is built like the proverbial tank




As you can see (or rather can't see) the lens dwarfs the camera stuck on the back.


Cheers,

The KPS eyepiece I have (looks the same as this one), fits both my K20 & K7 with the Pentax adapter that came with it.

As Clarky says, the viewfinders are exactly the same size (and indeed have been the same since the M-series cameras were introduced).

£600 and you don't even get the original caps

Asahi (旭 - "Sunrise") is a common product name in Japan, for obvious reasons.

Wouldn't surprise me if you can buy Asahi sanitary products for example

I spotted this one after it had finished Splendid 1957 Asahi Pentax original SLR w/ 58/2.4 lens

But even I'm surprised by how much it went for

R

I have one of these and it works just fine (although it is definitely cheap and plasticy).

Just goes to show you shouldn't believe everything you read on the Internet

It supports TTL & Manual (at full power flash), but not P-TTL.

So on my *ist D you get full automation.

On other Pentax DSLR's you have to use it in Manual (ie vary the aperture & ISO to get the right exposure).
Given this is used for Macro where you tend to be a consistent distance from the subject, I haven't found this much of a problem!

Agreed, I don't know why everyone is so down on it :

I used one on my MX for years as a lightweight travel combo and took some of my favourite shots with it.

I only retired the 40 when Pentax brought out the 43 Ltd
