Pentax lenses on micro 4/3

I've recently been tempted by a bargain non-Pentax camera specifically to use with my Pentax lenses.
I know it may sound a bit like madness, but there is some logic to it...
With the short rear flange distance of the micro 4/3 there is room for some interesting adapters, the one I got allows my Pentax lenses to be tilted.
I can't afford a decent tilt lens for my DSLRs but for just over £100 I've now got a whole selection
So far I've only played with the M50mm/1.4, but it should also work with all my old full frame lenses. (the lenses needs an aperture ring, and DA lenses will generally have issues with coverage when tilted)



No doubt a similar adapter can be made for the Q mount but I've not seen them, and I suspect the crop factor is somewhat excessive, as I want to be able to use wide angles. (As it is my 28mm only gives me 56mm equivalent on the Panny - I'm going to want some old ultra-wides)

I've been looking at Kipon adapters for the same sort of thing. It seems you are happy with yours, do you mind saying which one and from where?

I'm not fully happy with mine, but have been finding it fun to play with.
I've had issues with the mounting being very difficult to get off the camera, which seems to be getting worse in use. I think there may have been a few screws that have worked loose...
The one I got was from Roxen on e-bay, but as far as I could see all the chinese models on e-bay look to be the same.

OK I am going to be honest and say looking at that photograph I really don't like it.

To me it looks like a photograph of a model set and not a real scene? I guess that is down to how this camera processes it images.

Have to say I am not a fan of how the out of focus sections appears to be foggy.

Hope that helps.

In fact just looked again and the more I look the less I like.

Usng old lenses and odd lenses on cameras is always a bit of fun, but it's possible with many combinations of kit.

The Q encourages it, with lots of adapters available. But equally, there are lots of adapters for K mount as well.

Sometimes when we buy something new it does encourage us to play for a while.
Best regards, John

I have used K Mount lenses on my Canon via an adapter (with decent results) but unfortunately most of my Pentax lenses are now DA or DA* so I can only shoot wide open.

One advantage of the Q is the tiny sensor, which means that cine lenses and all sorts of wonderful obscure lenses will fit and cover the format.

Thinking about it though, I haven't seen that many, if any, great images come out of these experiments, with any combination.
Best regards, John

Nope, nothing to do with the way the camera processes the scene but a deliberate effect of using the tilt of the lens. Normally, lens tilt/swing etc is used to improve the depth of focus* using the Scheimpflug principle. Tilting in the opposite direction, however, renders real scenes like models by minimising the depth of focus in a way impossible by simply using a wider aperture for a thin depth of field.

Best wishes, Kris.

*I do mean depth of focus which is a result of tilt+Scheimfpflug not depth of field which is the result of aperture.

Lots of film bodies, a couple of digital ones, too many lenses (mainly older glass) and a Horseman LE 5x4.

Nope, I meant the colour as a separate issue.

Anyone else think it looks like a model set?

What camera is it Petro? I am guessing it is some sort of bellows type set up allowing you to tilt?

Regards,

Martin

Yes but that's what most people use a tilt lens for.
(Or the majority of shots I have seen taken with one give that look anyway)

No most use it for architecture to prevent/reduce keystoning, I used mine for panorama shots when I was doing them. I never used shallow depths of field obviously for those types of shots.

It just looks to "me" to be a scene from Horny model railway.

Do a search on Google for tilt shift lens photos and the majority of pictures that come up look just like the one in the original post ... ie the model type

I want a lens which makes a model (in this case my son's garden railway) look like a full-size one!
Best wishes,

Andrew

That look is an an effect of this lens yes Mike, do a search in Google under "what are tilt shift lenses for" and it will refer to perspective control. That is what every other pro I know uses them for except one who uses them the way above in his wedding shots.

In any event I would still like to know the camera so when you can Petro please let me know.

Many thanks.

I answered yes, I play with it occasionally. I have a Chinese PK adapter for my Pen camera and I have tried a few lenses. I should that a lot more.
