Manual focus lenses on Pentax K-5 II
Hi, I'm contemplating making the jump from my *ist DS to a K-5 II. Although I do have a few autofucuss lenses I tend to use a lot of the older manual focus lenses such as the 30mm/2.8, 55mm/1.8 and 85mm/1.8. I've read elewhere on the web that manual focusing can be a bit hit and miss with the standa...

I use manual lenses on my K5II. Cant say I've ever had a problem focusing them.

Manual focus lenses on Pentax K-5 II
I use manual lenses on my K5II. Cant say I've ever had a problem focusing them. Ditto on my K5iiS, except in very bad light. However, I still prefer the split image screens fitted to my old film ME & ME Super. Phil

Manual focus lenses on Pentax K-5 II
I've read elewhere on the web that manual focusing can be a bit hit and miss with the standard focusing screen on the K-5 II. It has been suggested that a EE-S screen gives a significant advantage in manual focusing. I'd appreciate any advice. The cut down Canon EE-S screen really makes a considera...

I am going to go off on a tangent a little on this one. I have owned K-5's and currently own a K-5iis and a K-3. There is no doubt in my mind that the K-3 is by far the best and most flexible camera for use with manual focus lenses, for the following reasons: - Viewfinder is marginally brighte...

I like the K01 as well David. But the K30 you suggest (and which is also the route I've gone) also has focus peaking and hence doesn't need a supplementary K01 just for manual lenses. Thanks for the clarification Rob. Is the peaking on the K30 the same as it is on the K-01? I understood the implem...

I'ev been meaning to get an EE-s screen to help but I'm looking at something with focus peaking now. you don't get the viewfinder DOF problems when using live view. Currently I use live view magnified to focus my 50/1.2 which has a DOF about the width of a Higgs Boson :) :) With live view you don...

This will be another bonus of EVFs. You can hold the camera up to the eye for stability and not worry about DOF problems of focussing screens. Add to that focus peaking in the EVF and we're starting to get somewhere :)

EVFs have the major disadvantages of being unpleasant to look at, having a lag if panned and needing to be powered up to have a quick glance through the viewfinder. A pentaprism viewfinder is still by far the best IMHO, clear, stable and precise.

Well John I don't agree with the stable comment. Try using the EVF in a mirrorless with IBIS (eg the OMD) then you get stability to kill for, especially with longer lenses. EVFs are getting better all the time, and the latest generations are much more pleasant to use. Really good ones are easier ...

Indeed, they will get better yet. I can't help but think though that the provision is driven by cost as much as anything else. A pentaprism may well be relatively expensive, although it costs no energy to run. Still, as long a we have a choice then that's fair enough.

I wouldn't worry about manual focus lenses on a Pentax DSLR with the standard screen. I wouldn't bother with a cut down screen for another system, you'd have to align it to perfection for any benefit. I'd worry far more about my technique - that is much more likely to be a problem. As for EVFs, I...

Manual focus lenses on Pentax K-5 II
It all depends on what we consider the human eye is doing when it assesses the point of focus. As far as I know a major part of this is the judgement of the point of maximum contrast. The judgement of the point of maximum sharpness could be quite difficult on a small focusing screen. For this rea...

There are special screens for some lenses, such as the f/1.2 ones and also the ultra-wides. Equally, long telephotos also have different screens ideally. The first 18mm lens, from Zeiss, had a special pink tinged screen supplied for the Contarex that the lens fitted.
