Many users still don't realise how to adjust the dioptre correction on the eyepeice and it's always a good idea to check that before going to the expense of other options.

Point the camera at a blank wall (defocused is best) and adjust the slider over the eyepiece until the lines etched on the focusing screen are at their sharpest. Job done. Now your eye is at rest when viewing the focusing ecsreen and manual focus will be much easier.

After helping someone else out with this last night, perhaps I should add also make sure the eyepiece glass is actually clean....

Maybe the lack of activity in this thread is because there's nothing really to add to what's been said?

It's perhaps too early to tell. There's an overlap with the 645D in that it's also a DSLR so I expect posts will find their way into various sections, and already have.

Possibly slight rotational movement of the camera during the exposure, hence the smearing. Even at 1/250s it is possible to get camera shake.

You can onkly really judge with the camera on a tripod and only then if the 2 second timer or a cable release are used.

It's hard to believe that an innocent thread about the I-10 could degenerate so quickly into bickering. I am asking you to put a stop to it now.

Honeywell Visitronic technology refers to their AF module, the first of its kind. The AF system was then licensed to whoever wanted to use it.

Sigma bother because they are a lower cost option available for all marques and they pick up business from the whole market, including Pentax.

Quite a few photographers opt for the 50-500mm.

Yes Oggy, but the point is that Nikon and Canon already have the users of very long lenses. There will be relatively few professional sports/wildlife photographers that are looking to move from those two established systems with their networks already set up for their needs.

As Pentax are relatively small they are not yet ready to attack that market, so are concentrating on the area they can achieve growth. It would be foolish to waste resources on marginally profitable exercises.

The 645D is another matter as there was an established range that could be adapted to the digital arena. Pentax have always been strong in the medium format sector, so know their market there and are successfully selling cameras and lenses.

Nobody is saying long lenses should not be made, but at any one time we need to be realistic as to what can be done.

The point isn't so much that there's no demand, clearly there is, but that when you offer the item eventually most of the demand fizzles away because of the price. It's more about priorities and what will enable Pentax to increase its market share. Providing something that is a small section of the market and already covered by others isn't the way to earn megabucks.

I always remember one gentleman who said repeatedly "I really want a ..... if only they made it I'd have one straight away." When it became available I went straight there and of course the outcome was, "I'll have to seriously think about that...." He never bought one of course.

The slight redesign of the K-r is actually brilliant. The rear screen gives all the necessary info in a very accessible wasy and as for battery life it's just amazing.

There is nothing to worry about and if the K-r was weather sealed there would be much less reason to think of a K-5.
