Leaning Pics

I would do a test with it, set up something studio wise or a table and get it all spot on and some printed thing and perhaps a bottle. Take the shot to show the problem and then take the image and camera back...

How long you had it?

It's not just me that's had the problem other Pentax users have also had it. If you check out the Pentax Users web site you will see what others have said about it.
I'm surprised to hear that there does'nt seem to be anyone on this site with the same issue.

Not many Pentax users, try Ben or Pete Smile

It has been said in these columns many times - put your money in the lens not the body.

My view is get a good body to put the lens onto.

If you can afford it.

Meanwhile, those of us who can't have to put up with these sorts of problems.

The register between focal plane, sensor, mirror, prism and ground glass screen is all important.

If any of these are out, and we are talking about very tight tolerances here to get an overall envelope tolerance, it doesn't matter how good your lens is, it is wasted.

Just the odd shot for me that I certainly put down to being careless with the tripod and not checking.

I would do as Tommy says and if you have real concerns then contact Pentax.

Bear in mind the camera is on the large side and can be heavy with some lenses. I now use a remote release avoiding any pressure on the right hand side.

Then that would that not be be evident in every shot?

I am saying that any of these deficiencies would impair the performance of the lens fitted.

In this particular case I understood that all of his pictures leaned, and so did the pics of other people he knew, or read of.

Generally in engineering various tolerances often cancel each other out thus producing a reasonable result. It is the nature of things.

If all dimensions occurred on 'worst case tolerance' then many assembled items would probably not fit or work together.

Possibly producing the sub-standard item that is attributed to the 'Monday morning, Friday afternoon syndrome! Smile

Perhaps Richard could confirm if they all leaned.

i would hope that in future we all take a bit more care when lining up our horizons.

Yes. It's done deliberately to make you buy the Pentax Self-Levelling Compensating Gimbal Mount . A snip at 2300....

Nah, he's just taking a new slant on the problem.
