Whilst there could be some truth in the suggestions made regarding reviews, there's a lot less truth in it than some posters seem to think. There are processes and skills involved and most proper reviewers do their best in the limited time made available.

To dismiss it all as no better than pure speculation is a bit extreme and can't be right either. If it was right, then we might as well not bother stating any opinions anywhere as they would clearly be of no benefit.

Balance in all things. There is some overly suspicious posting really. I never had any pressures one way or another doing a review, just a time scale. Of course, conspiracy theorists will never believe that.

No opinions are baseless Smeggypants, they are based upon experience and knowledge from a number of things and sources over a number of years. Providing references for every statement, as in a scientific paper, is not really a practical proposition.

Well, batteries do burst into flames, but fortunately it's very rare.

Manufacturers have their standards and OEM batteries are the least likely to cause us grief, but not infallible.

However, if a third party battery does damage our cameras, I'm sure the warranty of the camera will not cover it. The use of non-Pentax lenses isn't covered either, so if they jam or damage something that would be down to goodwill I suspect.

And that's before we even think about performance.

I'm not sure why people still think JPEG output fro modern DSLRs is poor, when clearly it isn't. Used properly, it is very difficult to tell the difference between RAW and JPEG originating A3 prints, if not impossible.

I'm also not sure why using JPEG for testing would therefore assume that the two main makes would come out on top. This is demonstrably not true and Pentax camerass probably produce the best JPEG output of the lot.

I say probably, because I only have personal experience of working in detail with Pentax, Nikon, Olympus, Sony and Fuji cameras. Of all those, Pentax is streets ahead, with Olympus coming in second without a doubt.

They play full screen on my Mum's Panasonic and on our friends' Panasonic, so it must be something that in the settings Chris. Of course there will be a black band either side if the ratio isn't widescreen.

Perhaps the lens article was just aimed at those who don't know. There was a time when all of us were totally new to photography and had no idea about anything.

Hopefully someone helped us along the way, especially with those first faltering steps.

It's a complex issue that depends not only on fitting the lens, but also on the back-focus distance to the sensor. Not all lenses can be fitted to all cameras. When they can, sometimes they don't focus to infinity and sometimes they are not easy to use.

SRB-Griturn are the experts on what is possible and what is not.

Academic interest as there are not many people who can afford thousands for lenses. And for the reason that thetimesaver has outlined as well.

We do have to be a bit careful of the fine line where commercial advertising and genuine interest meet. However, I'm sure that by now anyone interested will be able to find the listings easily enough.

Some of this thread was of academic interest to a few people, so it stayed for that reason.

However, as you've now pointed it out I have removed the post with the link in.

The lens is still available and will be fully functional on your K200.
