Funnily enough, I have an old Sigma lens which focusses perfectly on my Z1-P and*ist D, but not at all on two different SFX bodies.

As the 'Phone says, there are various options. It is odd, though that yours developed this problem so quickly. I would take it back to where you got it and ask them to fix it, because it sounds as though the camera came with a dirty sensor.

Failing that, the first thing to try is to blast some air at the sensor, and in my experience this is often all that is required. So far, I have cured my problems just with an ordinary blower, but you can get compressed air in cans.

If that doesn't work, then you're into sensor cleaning, and this is either a DIY job (if you're brave), or something you can pay for.

With film, it's scratches on the neg. With digital, it's sensor dirt. Nothing is perfect.

Prevention is better than cure. Avoid changing lenses in dusty places.

"gassin' Gazen, hmmm..... well I am only a dizzy female after all or is it dissy?"

I'm sure "dishy" is the right word in your case!

You're right, Pano.

However, most of the people making this elementary howler ARE English, and should know better.

How old are you, Bobbie?

You have quoted the answer:

"The compact, high-performance, interchangeable smc PENTAX-DA 16mm-45mm F4 ED AL lens features a 3X zoom ratio with focal lengths covering ultra-wide to moderate-telephoto ranges for the angle of view equivalent to 24.5mm-69mm in the35mm format."

It means that the angle of view on the *ist D is the same as a 24.5-69mm lens on a 35mm film camera.

Yes, but no delivery date has been announced yet.

I rather doubt that Pentax-NL is correct, for three reasons.

First, I haven't heard this anywhere else, and I subscribe to the PDML and read DPReview, both of which tend to latch onto new news pretty quickly.

Second, it doesn't make sense from a business point of view to replace the lone DSLR in the line with another lone DSLR. What Pentax needs is two or three different bodies with differing specs and different price points.

Third, I doubt they would leave it to Pentax-NL to bring this news to the world.

However, stranger things have happened.

Are you also known as Ronnie, who posted an almost identical question in another part of the forum?

Here's a source of information:

The AF360FGZ and AF500FTZ are expensive, new or second-hand. If price is important, the AF400FTZ is good and sells for much less than the other two.
