The choice is pretty clear - a compact high quality lens or a much larger wide aperture lens, which will be expensive if it's going to be equally high quality. Most wide angle lenses are used at smaller apertures, although on APS-C a 21mm is not particularly wide.

All excellent. What's the location?

With these cameras, when you set the date and time double check that you have scrolled down on the final screen to save changes. If the date and time isn't confirmed it will need constantly re-entering. It's one Pentax menu design element that is actually prone to error.

That's what I assumed.

Which Samyang lens is this Gareth?

I agree the whites of the eyes may be a little dull, so brightening them up a tad could be helpful.

It's very hard to understand how anyone could think it was something that should be done. Clearly something is very amiss with the thinking process of some people.

My first camera I found in an old travelling trunk that had all my Grandparents old discarded stuff. It was a wonderland of things that suited an small boy very well. Rooting about revealed old clocks, old medical equipment, and a Kodak 620 Junior Box Camera. 8 shots on 620 film. I still have the camera and last used it maybe about 5 years ago.

My first Pentax was around 1976, when I could finally afford a Pentax SP1000 with 55mm f/2 SMC Takumar.

My first Pentax digital was the *istDS.

Viewfinder can be used without having to switch on camera; Long lenses handle better than trying to use a screen image; Pentaprism gives better view that does not lag with action shots; Tracking and panning easier; Easier to use viewfinder in very bright light; Much larger lens choice; More stable cameras for hand holding; More physical controls as opposed to dipping into menus; Faster response and less shutter lag; Larger batteries for more shots per charge; Better weather sealing......

and I'm sure lots of other reasons too. Hope that helps!

I think things look very promising, so we'll see when the choice is there and the costs are known.

Even though I don't necessarily need a FF camera, never say never. I am persuadable.

It's a different discussion really, but there are so many ways in which mirrorless cameras can't do what the DSLR does. Sport, wildlife, studio, wedding....all are so much easier with the DSLR.

I can't see any mirrorless camera working well with the 150-450mm zoom and similar lenses.
