A K1 would be a serious option. Wonder if I can rent one??? Hmmmmmm.... :idea: Try SRSMicrosystems. Their website says "We carry the largest range of cameras, lenses and accessories in the UK and also exclusively offer a rental service for Pentax equipment.". There's also the Pentax 645Z if you c...

There's always the chance that 'Pentax' colours come from the glass and bayer layers rather than sensor response so the K-1 might be more of the same. But it's worth testing for *science*!

Short lived…….
…….. yes my newly acquired Pentax K-3 mkIII has gone back to WEX after little over three weeks. When purchased it was advertised was only 1000 activations. After a further 300’ish additional activations the sensor shutter failed. WEX have been brilliant with helping to sort the issue a replace...

Short lived…….
You can get problems with K1s as well - I have two and both do the same thing. Leave them idle for a few days and, after power up, the first shutter release causes the mirror to go up - and that's it! The shutter does nothing at all and the sensor records what it sees - nothing. When you 'view' the ...

Unexpected Expense
I wouldn't pay it. An extra £180 gets you a working K-1 with two card slots, and one card slot is enough for your current camera to deliver good shots. Just pretend it's a "Pentax KP Mark II" with a huge sensor! And if you want a decent K-1ii, you can sell the faulty one and still pay less than £...

Unexpected Expense
Presumably VAT takes care of £120 of that £720. Of the remaining £600, how many hours of skilled labour does it take to dismantle then reassemble a flagship DSLR? And that's before the cost of a circuit board. Then there's probably things like cleaning the sensor and replacing seals (even my watch g...

Fairly wide angle advice
Hello, I'm back into using my camera after a few years off, i just acquired a 16-85mm for my holidays, unfortunately i was dumb enough to buy a "cheap" Hama CPL which i left on the whole time (lazy?!), my photos are mostly soft. I will try next week on a trip to Amsterdam, using a new expensive CPL...

Disappointed with results when using a Pentax 1.4 x convertor on a Pentax 150-450 lens
So 450mm on a crop camera is 695mm without a tc so you'd need to be 1/800 sec minimum and roughly 1/250 with the tc The 450mm is still a 450mm regardless of sensor size. The sensor size affects field of view, not focal length. A 450mm on an APS-C body has the magnification of a 450mm lens, not the m...

Disappointed with results when using a Pentax 1.4 x convertor on a Pentax 150-450 lens
Perhaps just to add to the conversation (or confusion) - does the shake reduction need to be dialled in as 695mm? Also, if using a tripod, the shake reduction should be turned off? The SR input needs to be the true FL of the lens, no matter the sensor size. 300mm on the Q7 can be mental!

It shouldn't be necessary to dial in the FL, the 1.4TC should take care of it. But it does make me wonder whether SR might be contributing to the OP's problem. SR isn't designed for waving a lens around to track a bird in flight. If on, it might be moving the sensor in a random direction during the ...

The rule of thumb about shutter speed vs. focal length of lens is nicely summarised in (ignore the 'Beginners' in the title, it's just a good summary of what it's all about). Key to it is that the rule of thumb is from the film era, it's essentially what you needed to do to get something like 7x5 ...

New DSLR Rumour Mill
My cameras have not stopped working, my K mount lenses in all their guises (original K, M, A, F, FA, DA, DFA) all still work. The doom and gloom naysayers and out in force as are the mirrorless superfan trolls - it's amazing how Pentax just seems to wind them up. A few things stand out. The ha...

New DSLR Rumour Mill
The compute from the K-3iii into a K-1 or the sensor from the K-1 into the K-3iii would be goldilocks for me. When I use the K-1 after the K-3iii it feels slow but the K-3iii output is not as clean as the K-1. Nothing is wrong with either camera, they both perform their roles perfectly. But an updat...

The Current Chapter of Pentax DSLRs Is Officially Over
I think there is scope for radical innovation inside the DSLR that can result in a smaller, lighter, pocketable, more easily used camera which still gives the full 'real camera' experience for people wanting to take a step (or two) up from a phone. If I were head of R&D for the next gen Pentax DSLR,...

The Current Chapter of Pentax DSLRs Is Officially Over
I had a dream. And the dream was that I was looking at a newly released camera and set of lenses, all sporting a Pentax logo. The camera was small, perfectly formed, light weight and felt wonderfully comfortable in the hand. The lenses were also small and balanced well on the camera. And I heard ...

Pentax-A with a flash - Lensd setting when taking a flash
You cannot use the A setting on the lens with the Pentax K1000, which is a fully manual camera. You are correctly setting 1/60 which is the flash-synch speed. On the automatic flash gun there will be some colour coded settings for automatic operation. For example, one of my guns has a red and blu...

Flashgun for K1000
I forgot to add that there is no compatibility issue with the K1000. It has both a hotshoe and an X-sync socket, but offers no flash features other than triggering the flash. This means that virtually any flashgun from virtually any manufacturer will work with it. As there is no dedication facili...
