so you never know. Perhaps, maybe?! I suspect more than likely.
There's even a new Super 8 movie camera being made (to keep Richard happy!)

The F* lens was discontinued 26 years ago so why not get a more recent incarnation while the insurance company is on board? Being a rare lens there's no guarantee you'll ever come across another decent one.
Have you looked into getting the cracked element replaced?

That's fine, similar to what I got on my K-5. I must say I hadn't realised the extent its got wrecked in the recent models.

It isn't that different to my K-S1, surprising. I did some railway video on my K-5 and that was steady as a rock.
Anyhow, it got the picture I wanted last Sunday so was a successful means to an end.

That sounds like a fault. As we know, the K-S1 doesn't use sensor-shift for SR, only software SR (MovieSR) . Thing is, the sensor plate is still powered on even with SR switched off in order to hold the sensor in place, otherwise it slops around inside the body.
Thanks for that. Well I do not know whether the SR is sensor based or not but this review suggests it is:That sounds like a fault.

[quote="Expert Reviews"]This wasn't the only issue we spotted with the K-S1's videos. There were pronounced aliasing artefacts such as moiré interference on repeating patterns, and more noise than we’d expect from a large sensor. Rolling shutter effect was quite pronounced, skewing geometry of fast-moving subjects or when quickly panning the camera. The sensor-based stabilisation behaved slightly oddly for videos, too. None of these issues was disastrous but we wouldn’t recommend this camera to keen videographers.[/quote]Original review here: http://www.expertreviews.co.uk/digital-cameras/dslrs/1402085/pentax-k-s1-review
Well for another time (if it ever happens) it is turned off now!
The only reason for using video was to catch the flash from the cannon fire and it achieved that OK
Only one frame contained that so would not have been possible to capture that in stills mode.
The actual video is here (its only a couple of seconds.) The wobble is quite weird.

The HD DA15 is superior into the sun, is comparatively tiny and light, beautifully sun-bursts, virtually zero glare, superior colours, doesn't blow the highlights as much, takes filters and the small Hi-tech 67 system without vignetting, superior microcontrast and colour contrast, superior rendering, virtually zero distortion,has auto-focus and is great with close ups too.
It just is a superb lens and you can crop 10 photos from one image and they still look great. You could spend hours of fun pixel peeping even if you are opposed to such practice. The photos also require little processing so less time on the computer too.
As a mountain photographer and hiker I trailed the Samyang over the Mourne mountains several times whilst knowing I needed the DA15 and I'm glad I did, as true of the Samyang for astro as I was able to photograph the Milky Way albeit faintly from the suburbs of light polluted Belfast. The lack of coma is the other reason why the Samyang 14mm is suitable for astro.
I'm hardly knocking the Samyang and I've a good copy...

Hope this helps
Given this thread is about lenses for the K-1 the DA 15mm doesn't meet the criteria for full frame use whereas the Samyang 14mm does. However the SMC Pentax 15mm F3.5 dating from the 1970's is another matter. Wouldn't that make a fairer comparison to the Samyang?McGregNi wrote:

Comment by JAK posted on Which legacy lenses for K1? at 21/02/2017 - 10:14
Over the weekend I took a short video clip on the K-S1 (a rare event for me!) Unfortunately the video oscillates up and down. On checking the camera settings I discovered sensor stabilization was turned on by default so I have now turned this feature off. But Richard is a devotee of this so called sensor stabilization and I'm really wondering why. I can now understand why Pentax have removed this feature from recent cameras so why would anyone want it back?
The only reason for having it would seem to be to simulate a worn film passing unsteadily through a projector film gate. It's the antithesis of stabilization!

Set the camera to raw+jpeg and should you decide afterwards you want a colour image you can process the raw file to provide it. You'll still have your mono jpeg as originally intended.
Having said that, they're all fine as they are!

In this case the weather sealing may have sealed the damp in the camera rather than let it evaporate.
If one's going into a humid jungle one might be prepared for such an eventuality with sealed bags and silica gel, but if one just ends up humid conditions unexpectedly I suppose the problem can just happen upon you.

I have a F*300f4.5 lens, very beautiful white colour, small, and interesting. but I have to say the DA*300 f4 is a better lens.
BTW: the F*300f4.5 and FA*300f4.5 share the same optic design with different appearance. but the DA*300f4 is believed a new design one.
