I think this has been exhausted now as a subject....

I can understand how you feel, just don't forget that computer systems are mercilessly impersonal, so I would go through the process of appeal.

Hope you get it sorted OK.

eBay do not interfere in feedback unless there are very limted circumstances, such as someone posting your phone number in the feedback, or something illegal being posted, so they won't remove unfair negative feedback.

Using the Unpaid Item Dispute system both parties can agree to resolve the issue with no disadvantage to either side, so it might be worthwhile negotiating that with the seller.

Only you can make the decision, but the price does seem very very low...

Yes, and quite a big name magazine too, but unfortunately I can't remember which one!

Why not return it direct to Pentax and see what they say?

"Correct" viewing distance only refers to the distance required for the perspective to be correct and does not imply that you are forced to observe this. In fact, if you did, you would negate many of the advantages of using different lenses.

Large TV screens are designed to be viewed further away, and in the same way large prints are as well. It would be silly to attempt to view a 6 foot by 4 foot print by holding it in your hands, wouldn't it?

As the Image Size dialog box in PS will show you, ppi alters and image size can alter with it, so without interpolation you can change the size of an image. The bigger it gets, the lower the ppi and the further away it will have to be to maintain its apparent sharpness to the eye.

The smaller print that you look at closely is no sharper than the poster hundreds of feet away, it has the same amount of information in it, but in the small print it is so small that you can only discern so much. The eye's limit is about 4 lpmm in a moderately large print, if I remember correctly.

George has raised a very valid point - that of viewing distance. To keep the perspective correct, bigger prints should be viewed from further away, at which distance you need less resolution to maintain the quality level.

Equally well, wide angle shots viewed very close have normal perspective and only look odd when viwed from greater distances.

Conversley, when viwed far away, telephoto shots lose the telephoto look and give normal perspective.

I demonstrate this by using a large print taken with the SMC Pentax 15mm f3.5 lens. Anyone with short sight can view this print at unusually close distances and will find that suddenly the picture looks quite normal, losing all the ultra-wide look.

Try it and see...

The Asahi Optical Company started off with the Asahiflex in the 1950s, introduced the Pentax when a fixed pentaprism was added to the cameras in the late 1950s.

The cameras were called Asahi Pentax except in the USA where they were Honeywell Pentax, named after the distributer there. Camera models were identical, apart from a flash sensor added to some of the USA variants.

In the late 1970s or early 1980s the Asahi name was dropped and the camera became just Pentax.

That's a very brief history and if you want all the details there are several suitable books that cover it!
