Sorry i have only just caught up with this thread again! It does indeed work with Auto lenses with an AF MF switch. I use it occasionally with my DA* 16-50 and 50-135 lenses. Though it is with my 1970`s 300mm f4 that i use it mostly as every shot is pin sharp even when the subject is only in focus for a fraction of a second. I have`nt used it with my K5 II yet but it should be at least as good!andyvarney wrote:

Catch-in focus only works with manual lenses, and when the AF switch on the camera set to AF-S. You may have thought you were using it with auto lenses, but it wasn't working.Now that's clever, I have used that feature on the auto lenses and that makes sense to use it on a manual, so I assume when it's in focus it fires the shutter.

One other thing that i personally find useful with manual lenses on Pentax DSLRs is the Catch in Focus feature. Whereby you keep your finger on the shutter button and the shutter will fire when the subject comes into focus! The feature has to be set in the camera menu and Autofocus selected on the camera.

Hi i-Berg,
Your shots are still pretty good,A slight tweak in Photoshop (or other photo software) should have them look sparkling!
The best way to take aerial shots from your Cessna is to shoot through an open window. Failing that fit a soft rubber lens hood and get as close to the perspex the perspex as you can without touching (so as not to pick up vibration from the airframe.
Polarising Filters can reduce glare from reflections and intensify blue sky if used at the optimum angle but they cannot always make reflections disappear completely.
Best Regards - Pete

It may help if you open Photoshop- Go to Edit - Preferences and then adjust the amount of RAM allocated to Photoshop.

My bible has been the Photographers Handbook by John Hedgecoe, I bought my first copy back in the 1970`s and it was always full of inspiration and advice. O.k a large proportion of it deals with film but There is still plenty that is relavent in todays Digital age. (Only the Media has changed not Photography itself!) You can pick up a copy for under £3 online if you shop around.

I have a feeling in my bones that a Pentax FF will not be too long a wait!
But for now the K7 is still doing fine for me.

Could be, I saw a green/white Piper Arrow at Coffi Airport yesterday that is the same colour as Mona Flying Clubs one. It carried an American Registration No, I am not sure without checking what Reg Mona`s aircraft is. When i flew in it around 3 years ago it was owned by a doctor but operated as a group aircraft so any member could fly it just paying for the fuel and related costs.PeteL wrote:
i have been up with them was a flight around Anglesey in their Piper Arrow. Unfortunately i was in a rear seat on that occasion and was trying to shoot through badly scratched perspex. Lots of PP there! Still it was free and we did do a complete circuit of the island. All 125 miles in 1 hour!!!

That's exactly what we did Pete, same plane I'm sure, the wife was in the back though and the front windows were pretty good. We just missed out the end section of Abermenai point, pretty much covered the rest. the pilot did a nice 360 around Penmon, hence the perspective on the shot - the Gyro wasn't too happy thoughi have been up with them was a flight around Anglesey in their Piper Arrow. Unfortunately i was in a rear seat on that occasion and was trying to shoot through badly scratched perspex. Lots of PP there! Still it was free and we did do a complete circuit of the island.

It was quite a smooth, powerful ride as i recall.
Yes i was impressed with your Penmon Lighthouse shot as you got the tide just right so that the pathway leading to the lighthouse is completely uncovered. All of the aerial ones i have taken the tide has been high so the lighthouse is completely surrounded by water. They don`t look half as good as your`s. I will have to check tide times next time i book a flight!

I hope that not too many shot`s were affected, Could it be possible that it is the perspex window rather than the lens causing it. I have had several images where that has been the case when shooting through perspex.
You are right, Mona Club are a bit more laid back in that respect! The only time i have been up with them was a flight around Anglesey in their Piper Arrow. Unfortunately i was in a rear seat on that occasion and was trying to shoot through badly scratched perspex. Lots of PP there! Still it was free and we did do a complete circuit of the island.

I keep hankering over a microlight flight from Caernarfon, It won`t be easy getting shots wearing a visor, I might have to use the live view. Also the pilots head is only a few inches below you and the engine and prop just behind!!! I will get around to it one day.

I think it's worth practising using our eyes - such a simple thing that seems to have become lost. To do this, we need to make sure that the dioptre setting is correct for our eyesight or, for cameras with no adjustment, that we have the right glasses on to ensure easy, relaxed eyes that can focus on the focusing screen properly.
For example, I use my reading/computer glasses for older manual focus cameras. If they can be adjusted, then normal glasses can be used. I have avoided bifocals and varifocals as I'm sure they make focusing cameras more difficult.
Just turn the focusing ring until the image is sharpest and you should be in focus. Some do find this difficult I know, so just practice because the eye compensates and there can be some variation in the point chosen.
