I haven't measured the tones in PS, I'm just saying what I've observed.

Would some 255 pixels be acceptable? I'm coming round to the view that they might be if the context is appropriate. Nothing is set in stone and all rules are up to be broken....

Having said that, I'm not suggesting that blown out areas would be OK, just that out of 14.6 million pixels I could overlook a handful here and there!

No blown highlights on my screen.

The easiest lens to design for a format is one just slightly longer than the standard, so 85mm and 100mm lenses should be amazing.

All the MZ series can suffer from the flash spring failing, but I've never had one that has,

Both made in Pentax's Vietnam factories, so how much sense would there be for them not to be the same?

When I look at the coatings side by side they reflect the same to my eyes, so maybe they are the same.

I'd be happy with either, but because of resale values later on the Samsung one would have to cost significantly less IMHO.

1998. Yes, indeed! A slip of the keyboard.....

My MZ5 and MZ3 cameras are both still going strong. Sometimes faults may occur, but not to all of them and if the OP buys from SRS there's that useful guarantee period.

For £25.00 how wrong can it be?

That looks fine, very little to say about it really. It's a good clean shot of the moon that ticks all the boxes!

Not easy to do and you've done it well.

All Pentax AF lenses will AF on your cameras, including the 80-320mm. This lens received excellent reviews in the press and is a good one, probably slightly better than the 100-300mm.

Some data for 100mm (or 105mm) lenses, again from 1981/1982.

As we can see, the Pentax lens in this group is a star, even without a *, and we know that this lens has always been highly regarded. I've owned several, and all have been sparkling performers.

I don't take holiday snaps, I go on "holiday" to make photographs of places that are out of range for a day trip.

Party pictures and things like that I leave to others, or, if pressed, I use a compact digital camera.
