You are likely to find that the Pentax images are warmer, but in fact the colour quality is one of the special things about Pentax.

However, I wouldn't worry because any differences will also depend on your computer system, monitor and how you adjust the final images. You can also change the JPEG settings in camera anyway to give you what you like.

Thanks bb2, and this highlights the problem, if it is a problem. The images with zoom lenses look as good as the images with primes, so the areas of use for the primes become somewhat limited. No pun intended.

The primes come into their own when light levels are very low and/or wide apertures are needed.

A bit more information here would be useful if you are making a Classified Ad. There are no cloues in this to attract the casual reader and at the moment you are relying on someone doing an eBay search to see what it's all about.

Pictures too please if you want to tempt us.

Yes, my images are pre-uploaded in my EPZ portfolio, as we can now upload multiple images per day and then submit them to the gallery one per day.

It's the early hours of Monday now, so strictly it was yesterday that we spent some time in Ness Gardens on the Wirral. It was originally intended to be the Yorkshire Air Museum, but Tardis-like we strayed off course slightly.

The exercise for today was "one lens" - Sue chose the SMC Pentax-FA 50mm f1.4 and I chose the SMC Pentax-FA 43mm f1.9 Limited.

It's an interesting thing to try and we may do it again. It makes the photographer work harder to get the right images. As a general rule though it did confirm in my own mind that I've pretty much moved away from using prime lenses.

There's no denying the fine qualities of a good prime, but too many shots are just impossible. It made for an entertaing session nonetheless.

Not at all. What may be perceived as bias could in some instances be just a reviewer being unaware of something, and therefore inaccurate.

For example, there was an AP review of the Samyang 85mm f1.4 some time ago and the Nikon version was tested. The reviwer, who was very experienced, was unaware that some versions had full coupling, unlike the Nikon ones. So the fact that the Pentax fit is a full Ka mount was completely overlooked. This wasn't bias, just lack of information, possibly because of lack of time due to deadlines.

I would start from the position that, in general, people are trying to do the best job they can.

The 50-500mm is an excellent lens and I've seen some superb wildlife images shot with it.

Excellent idea and lovely crisp image.

There is a pattern to the numbers and I would expect a 928 to have a 28-90mm lens.

Yes, there are a large number of Pentax Espio cameras, using 35mm film.

They started off with 35-70mm lenses, but later ones had wider ranges. A search on eBay should come up with lots of them with very low prices attached.
