Recently went to a Rotolight workshop which changed my mind about LED lighting in a studio setup. They are powerful enough to work at ISO400 at normal working distances.
I've not been converted to them for outdoor use though.

Comment by Tyr posted on Pentax K-1 surprises. at 06/10/2018 - 21:52
However, what really surprised me was the camera's focus motor. All other Pentax cameras I've tried sound like a cordless drill. The K-1 is completely unobtrusive. It is not silent but it is, in my opinion, amazingly quiet! Why isn't more noise about this little gem of a feature?
It feels better in my hand than any other Pentax, even the K10D. The grip fits my hand just right. The controls are easy to reach and have not deviated much from my K-5. I can't say the same for the K-70 and K-P.
It is a bit bigger and heavier than my K-5 but not by as much as I thought.
Problem is, it made me want one more than I did before.
I'm not sold on the massive FF lenses but can still use many APS-C lenses with most the frame. Simultaneously shoot APS-C portrait and landscape as well as making composition adjustments easily on a crop lens as you can see what is just outside the frame.
It would suit my needs rather well.

I need a new CPU as mine is old but my SSDs are still going strong. The older SSDs I have are 3x 480GB ARC100 drives (good at the time and still good now). I wouldn't buy an OCZ/Toshiba SSD anymore though. Their new products are terribly slow (barely better than hard disks).
The industry leaders for price/performance balance are Samsung EVO860 or Crucial MX500 drives which are comparable. I went for a 2TB MX500 a while back as my photos drive as it was 50% off at the time.

[quote:3496ace15f="Tyr"]It is a shame that LCE stopped carrying Pentax as it was nice to handle items before buying.

This is sort of a mini-review of the teleconverter at the same time. I'll let the pictures do most of the talking though.
Migrant Hawker with DA* 300 + HD DA 1.4x.

This lens is so sharp even with the teleconverter. I've not noticed any loss in resolution on the K-5. Cropping certainly doesn't give me the same magnification and detail gains as using the TC. The image below is practically the whole frame, very minimal compositional cropping (over 90% of the frame).

With the aperture wide open depth of field is obviously very shallow. The sharpness is still there in the sliver of focus. It isn't visible below because of the resolution of Flickr but the lenses on the eyes are starting to be resolved on the full size image, there is plenty of detail and texture. Bokeh isn't quite as nice as without the TC though, seems a bit nervous in places.

Ruddy Darter with DFA 100 WR + HD DA 1.4x.
90%+ of the frame just cropped a bit for composition.

027 by Daniel Perlak, on Flickr
Again nearly the full frame cropped only for a slight composition adjustment, Loads of detail and contrast. Great for the increase in magnification and/or working distance.

I didn't manage to get down the minimum focus distance/maximum magnification. This darter was very skittish and that is about as close as I managed.
All in all the teleconverter is amazing with both these lenses. It has given me a 420mm f5.6 telephoto and a 140mm f4 super-macro. I am very pleased with the image quality with negligible loss in resolution or increase in aberrations. There is more than enough resolving power for the K-5 and therefore the K-1 (almost identical pixel density)(now all I need is a K-1).

Not always!
K-5 with DA*300 f4 + HD 1.4x TC (630mm f8 equivalent).
OM-D EM1 ii with 300 f4 Pro (600mm f8 equivalent).
The Olympus setup is actually heavier.
This is comparing the Pro lines lenses though. Stick the 45mm f1.8 on any Olympus body and it is tiny! It even gives the Limiteds a run for their money!
