Some nice low angles bring things down to your subjects level there, and the flash exposure looks good also ..... I'd have probably gone about a stop lower on the ambient background exposures here, they look a little bright, and you would get more depth and colour at about one stop less. Glad to see the HSS techniques are still proving useful!

OK, but I'm saying that you may not have to crop right in as far as the APS-C border. In terms of pixel resolution then yes, the K3 out-numbers the K1 at the full crop size, but if its a choice to be made, then you can still get a great deal out of a K1, and say a 300mm lens, if you can't afford longer FF telephotos. I suppose my argument is that this factor does not necessarily mean that 'aps-c is better for wildlife', based on 'reach' alone. Its probably a personal decision based on budget.

If I was buying a K1 for landscapes mainly, but had a good 300mm lens also, I wouldn't then say 'I must get an aps-c model as well for my wildlife shots'.

It's refreshing to see some Lakeland landscapes here again, and it looks like it was refreshing to be there as well!

Very nice skies, with a good depth to them and smooth tones. My pick of the bunch is No 5 for the strong composition.

We keep on reading the same 'extra reach' argument made all the time, supposedly suggesting that aps-c is better for wildlife because you don't need such long expensive lenses (e.g a 300mm is enough instead of 400 or 450) .

But the reality is, surely, that there is no 'extra reach' ....reach is the magnification that the lens provides, and that stays the same regardless of the camera format.

What changes is the amount of space we see around our subject through the viewfinder. This creates what I have described here before as an 'optical illusion' that the subject is bigger. Whist it may mean that the composition is easier to achieve nicely in the camera, a simple crop away of excess space on the FF image will leave you with the same image, won't it? It may not even be needed to crop all the way in to the apps-c frame boundaries.

Yes, maybe. I think that for a number of years now, for many of us, money spent on better lenses would reap more rewards than the same amount spent on a better sensor. But if you already have all the best glass, then you might as well get a K1 or KP!

I agree on the Pentax models there. It sounds like you need on-camera P-TTL with bounce mainly, so I'd look out for a well priced Pentax AF-540FGZII ....discounts come around sometimes. If you're not working in large rooms then the 360 model might have enough power for your needs.

Yes, try it out by all means. The reason that radio HSS is so sought after is that the liimitations of optical triggering are really challenged in typical HSS situations , ie outdoors in bright light.

I manage with optical triggering fine, but I'm careful to place the sensors facing the control flash and work at fairly close proximity ...Generally I'm working at around 3-5 metres max (like in the 'teddy bear' demo).

To get that really dreamy OOF bokeh you often need to be well back with a long focal length, and then optical triggering will struggle, especially if the sun is shining towards the slave flashes.

It would help if you gave an idea of how you plan to use it .... What subjects, on or off camera, in which sort of situations. Plus some idea of your previous experience and use of flash previously. This will all make it easier to suggest specific products or entry points into different types of flash systems.

Very effective! Nice use of lines / diagonals, and the closeness has real impact. The fact that you've managed to get the eye of the right hand bird visible also is the icing on the cake.

Ha ha, and yes, the entire forum membership is gripped to the topic, putting aside all their Easter celebrations in eager anticipation of each new post !

It opens up plenty of new possibilities for sure. The only thing I'd hold fire on for now, and certainly I can't comment on at this stage, is exactly how multi-flash P-TTL will be implemented ...ie how exactly will we control the individual output of more than one flash (eg will the V6II have compensation settings for each group?, and will we still have use of "wireless lighting ratios" on each flash?) . We'll have to wait for the firmware to be released to know the specifics probably.
