Airshow photography with K5
Forgot to mention, check out Back Button Focusing ( BBF ) and practice the technique before attending RIAT

always good to talk aviation photography particularly with a fellow masochist using Pentax cameras pre K-3III!
I've used a K-50 for several years and have been using a K-5IIs for past few months. Over the years i've shot well over 10,000 aviation images with digital equipment.
My thoughts...for what they are worth...your Pentax 55-300 will be your best overall choice by far if restricting yourself to one lens although it has two major limitations...1) not WR (assuming) and 2) AF with K-5 is very slow.
If RIAT is dry ...not a problem...if very wet could be a major issue.
My 55-300HD WR great if wet but slow AF...I can usually only get 2-3 shots before it loses AF when aircraft flying towards me (as in getting closer not necessarily head-on)
I've only ever been to Mach Loop when I knew weather was dry...no point in going otherwise so not an issue here particularly.
Any 55-300 lens is ideal reach wise for both RIAT and Mach Loop unless you want to capture epaulette rank badges on pilots shoulder...in which case you will need a quality 300m to crop or a longer lens. (as Chris mentioned).
If the weather is dry when i'm shooting aircraft these days then my preference is to shoot with a manual lens
and benefit from no AF problems. Suits me better as I grew up with successive 35mm film cameras when used to MF all the time. With aircraft you are shooting close to infinity vast majority of the time so most focussing is just small adjustments within a very limited range. If the focussing is slightly out you've messed up the shot, BUT better a slightly OOF shot than miss it altogether due to poor AF performance, and when you get it right it's usually very good with a sharp lens.
I've recently been using the Samyang 135 F/2 which i'm very pleased with. Reach isn't fantastic but adequate most of the time at airports/airshows and if you nail the focus it will crop nicely up to 75-100%. As it is designed to be MF the focussing ring is very nice to use, wide, easy to grip and well dampened. I've also used the Pentax M 80-200 F/4 which is reasonable IQ and quite compact and light. The Samyang as well also works ok with a Pentax 2x convertor i've got giving me effectively a 270 F/4.
Only other thing to mention is shooting style...i'm very much a sniper rather than machine gunner...single shots...rarely more than 4-5 in one aircraft pass...this works well with MF but not so well if you prefer to 'spray and pray'.

I like the idea of manual focussing. It makes sense as you describe it. I intend to go lurk at an RAF station or two soon to practice so I'll see how it goes. I'm quite sure that the K5 will 'out photograph' me but I'd be very tempted if a DSLR manufacturer was to bring out a high res SLR (preferably with a Pentax bayonet fitting) that operated pretty much as a K1000. All the bells and whistles can sometimes get in the way, I think.
I might add that my 'backup camera' is a Fuji HS50 which I rate pretty highly. I doubt very much that spending more money will improve my photography although it might feed my addiction to gadgets!

Agree with your concept of a stripped down, K-mount DSLR...i've often thought there'd be a niche market for it if the saving could be 15-20% compared to fully specced 'big brother'. I do occasionally experiment with some of the 'bells and whistles' but wouldn't miss many of them if they went. Similarly lens wise...i'd be very interested in a MF 200 F/3.5 with IQ , focussing ring to match the Samyang if cost was substantially lower than AF version.
One other advantage of shooting MF is that the battery lasts so much longer. Although I took two batteries with me to Old Warden recently for one of their flying displays, I only used one but still took about 1150 shots and had approx 5-10% left in it at end of day. (K-5IIs).
Anyway see how you get on at an RAF airfield...that's the sort of practice you would need. Air Force 'grey' and cloudy background is a good test of you and your equipment.












Good luck, and most important, don't worry too much and enjoy the day.

I've been away from photography for some time now, 2 or 3 years, but I've dusted off my two Pentax DSLRS, a K5 and a K20D with a view to practicing for an airshow or two (I've just bought my ticket for a weekend at RIAT 2022) I might be visiting the Mach Loop also.
To say I'm a bit rusty in using them is an understatement. I have a Soligor 18-200, a Pentax 55-300, and a Tamron 500mm mirror lens. I think I've got a Soligor 400mm telephoto too somewhere. I'll be out and about trying them out as and when, but some well informed hints on the K5 particularly, would be much appreciated in respect of photographing hairyplanes.
