Little live view A/F tip
Like Richard I too use LV to focus when the camera is on a tripod. Usually in manual mode with the zoom set to 100%.

Thanks Gareth, I often move the focus point around but I didn’t know/forgotten about the size adjustment. Cheers. PS everyone subscribe to Gareth’s channel!

Good luck with your K-5ii! I hope you have a great trip to Norway, with all its photo opportunities. A bit more than 10 years ago, when my wife was convalescing from some mysterious attack of neuritis, we took the Norwegian Coastal Ferry (Hurtigruten) round trip up the coast from Bergen to Kirkenes...

Split image focusing screen for a K3
I saw a comment on the Pentax Forum where a user mentioned the failure of a K3 to 'catch in focus' at 28mm when he had an old 28-135 zoom mounted. However, he said, there was no problem as he was using a NIKON split image focusing screen. My poor old eyes would love a split screen in the K3ii. (Ther...

Split image focusing screen for a K3
I have a Katzeye screen in my K200D and it's fantastic, much more accurate than the K-3's stock screen or even live view magnified with focus peaking. Alas, Katzeye are no more, so the options are cheap Chinese ones of questionable quality or cutting down a Nikon or Canon one, but that's certainly ...

Split image focusing screen for a K3
I have a Katzeye focussing screen in my K5 and it has made a world of difference when using manual focus lenses. I will miss it whenever I next purchase a camera body. Not had to use any shims and focus accuracy does not seem to have been affected. Perhaps I should check the manual to make sure :...

Split image focusing screen for a K3
Thank you Barrie. The link has some useful information. I've not noticed any focus inaccuracy but this may be due to me usually using f/2.8 or smaller with "fast" lenses, so the depth of field may mask any slight focus issue. I'll check the size of the shim fitted to the camera. There is a pos...

Split image focusing screen for a K3
I had to use shims to get focus spot-on in the K200D with the Katzeye screen. I remember I had to wait around a month and pay about 30 quid for a full set of shims from one of the authorised repair places. Shims are always a possibility regardless of the model. They make up for small difference...

Split image focusing screen for a K3
My MX has got a split screen. I was thinking of trying it in the K3. Any thoughts before I bust something? I think it'll be too big and need to be cut down and you will likely need shims to get focus spot-on.

Pentaxian with K-X wins Flickr 2019 Your Best Shots competition!
Congratulations to Robert Span on : Taken with the K-1 and SMC Pentax-A 70-201mm f/4. You've got to like his self-effacing comment: “I’m a 51-year-old amateur photographer based in Ontario, Canada. I’ve always been a Pentax user and have a keen interest in using their older CCD-sensor DSLR bod...

Teleconverter 1,4 with a 55-300 lens will it work ok
Also bear in mind that adding any tele-converter to a slow-focusing lens will make it even slower, and that's especially true for any of the non-PLM versions of the 55-300 range - been there, tried that and gave up very quickly, especially at airshows! The latest 55-300 PLM version focuses MUCH ...

Teleconverter 1,4 with a 55-300 lens will it work ok
Jason didn't say which teleconverter he'd get - if he is after the Tamron PZ 1.5 then that 's a full-frame version and some variants have the PKAF2 contacts for SDM/Powerzoom. I had the 55-300 briefly while the DA*60-250 was getting its' new motor - I was so glad to get the DA* back to be honest....

In what order..........?
Sorry to butt in. Same sort of question. What happens if you put "TUBE/TUBES" behind a 90mm Tamron macro lens?. Does it make it even more macro?. I've only tried my macro lens a couple of times so I'm not sure how it all works. Maybe I'll have another go sometime with a little help from my friends a...

In what order..........?
I've asked this before, but I don't remember the answer...... If you have a lens of F/L "x", if you put X mm of tubes behind it, you get 1:1 on the sensor. 50mm of ext. behind a 50mm F/L lens gives 1:1, etc., etc. My 100mm D FA Macro gives me 1:1 anyway. What does it give me if I use 100mm...

In what order..........?
the short version - 2:1? According to my book that has lots of formulae and says what buttons to press on a pocket calculator ---- Youre RIGHT! :D:D More generally, adding 2 x FL gives 3:1, 3 x FL gives 4:1 etc. The book does point out that the formulae are exact only for thin lenses (vagu...
