The bigger viewfinder will make manual focus easier, but to be honest I would be sticking to AF lenses. I feel that, nice though they are, the time for manual focus lenses is way past, at least for me it is.

A possible exception would be the macro lens, where manual focus is often the best option anyway.

To be full frame the image the lens projects onto the sensor needs to be wide enough to cover the 24 x 36mm frame. APS-C lenses are smaller and project smaller image circles, so don't cover the whole of a full frame.

In this context, full frame means a format size the same as 35mm film cameras.

You might find one on eBay at a reasonable price.

The Pentax Adapter K fits flush inside the mount and allows infinity focus. You need an adapter that fits the same way. Any thickness will prevent infinity focus and such adapters are only good for close up use.

It's just the way your adapter is designed that's the problem, so it's not really fit for your purpose.

Good choice, I'm sure you'll be delighted with the new camera. Don't forget to post some images!

This one is drawing to a close, but there's still time to enter.

One image has been removed this month, as it was shot a year ago in 2014. We're doing much better these days in getting our dates right, but another reminder that the Monthly competition is for images that are new. So September 2015 competition must be shot in September 2015. All other images are removed. or, if they slip by, then not judged.

The 28-70mm FA* lens started life at £1299.00 and that was a very long time ago. So the price of the new 24-70mm lens is very competitive by comparison.

Prices will also ease over time and no doubt packages will be available.

We're straying from Chris's post and his generous introductory offer.

Manufacturers often co-operate when it's to their mutual benefit. How much of Tamron and how much of Pentax is in the lens would probably never be known, but the Pentax seal has been placed upon it. We can safely assume that the first standard zoom for the new FF system will be quite deliberately a good one. Otherwise the initial tests and reviews would be a bit discouraging.

The lighting can be very mixed and constantly varies in intensity and colour. AWB can average it all out quite successfully.

Q7 and 06 lens should be ideal. i would start with ISO 400 and wide open at f/2.8, with -1 EV exposure compensation. Use Av with centre weighted metering and also set AWB.

If necessary, use ISO 800, but on a stage there should be plenty of light.

If your daughter is more spotlit increase exposure compensation to -2 EV.

Then see how it goes and adjust as necessary. Incidentally, shooting in JPEG should be fine and you should get lots of interesting lighting effects,
