Manual Focus lenses vs Auto Focus lenses
Check the adjustment of the eyesight correction slider on the viewfinder. Looking at a plain background (well lit interior wall, sky), adjust slider until the in-viewfinder markings are at their boldest. You should try to relax your eyes to focus on the far distance while doing this. EDIT: Oops. ...

Manual Focus lenses vs Auto Focus lenses
It's worth re-iterating the method to adjust the dioptre though as many users don't realise the viewfinder image should be out of focus whilst doing it so we can see when the etched lines on the focusing screen are sharpest. Once the dioptre is correct then the focusing should be correct. Are ...

Manual Focus lenses vs Auto Focus lenses
Are your AF lenses sharp when used with manual focusing? That's a very good question....I don't know and I haven't tried to used them in manual focusing... I will try this out and get back to you.. tks

Manual Focus lenses vs Auto Focus lenses
Well, I tested the AF lenses in manual mode and they were as sharp as in AF mode. I did readjust the dioptre but still I tried the 200 F2.8 lens and I 'think' it may be a little better but I'm not sure. Thanks guys for your help and comments. Certainly appreciated. Phil

Manual Focus lenses vs Auto Focus lenses
I would set your camera up on a tripod (if you have one), or on a stable, level surface. Then focus your lenses in Live View mode on the rear screen, zooming in to make sure the focus is 100% correct. Then take a picture with the self timer and check the result. If it is not sharp, I would suggest ...

Manual Focus lenses vs Auto Focus lenses
It is certainly possible to get sharp images with old MF lenses. I do it all the time. In fact, I probably use old MF glass much more than my new AF stuff. Are you relying on your eyes, or the green hexagon? It seems fine on my K-3 but I did have problems with the K20D where the green hexagon ...

Manual Focus lenses vs Auto Focus lenses
Kris is right there. You cannot rely on the green hexagon. In fact it sometimes lights, with a bleep in different places depending whether you are focussing inwards or outwards. The best test is with live view, as described above. You'll be amazed what a difference the tiniest tweak will make. I als...

David 'I would set your camera up on a tripod (if you have one), or on a stable, level surface. Then focus your lenses in Live View mode on the rear screen, zooming in to make sure the focus is 100% correct.' I will try this and let you know what happens Phil

Manual Focus lenses vs Auto Focus lenses
Well................ David, you were correct! I put the lens on a tripod and focused it in Live View and sure enough I got a good photo. So the problem was me. I'm both surprised and disappointed. As the lens is an F2.8, I thought it was fast enough to cope with this sort of thing. That means, th...

Bokeh and the HD 150-450
Link Posted 27/03/2016 - 06:57 Recent PU Quote in respect of the HD 150-450: "My only concern would be the bokeh" Not sure if the images below ( all taken with the 150-450) show "the good, bad or the ugly as regards bokeh" specifically; Whether there must be defined points in the ba...

Bokeh and the HD 150-450
Hi Daron The lens looks to be stellar in the sharpness / colour department, but I tend to agree with DrOrloff's comment on the bokeh, it does seem to produce 'messy' out of focus areas. You asked for an image with nice bokeh, the one below was taken with the DA*300, a lens which I think produces...

Bokeh and the HD 150-450
Hi David, Yes , for sure that is a wonderful picture and the bokeh enhances the image too. Definitely a very composed and well thought out image which has got me thinking about trying to take a similar type of image in order to answer the question regarding the " bokeh " on the HD 150-450 ...

Buying a used Pentax 17-70 f4 yay or nay?
I have found the DA17-70 an excellent lens, especially for walkabout. When trawling through my shots, many of my favourites were taken with this. I upgraded to a DA*16-50 - which recently had the SDM and clutch go wrong. JPSS did a splendid job on the 16-50 and it's now utterly lovely. However, ...

Buying a used Pentax 17-70 f4 yay or nay?
I have used a 17-70 as my main walkabout lens for maybe 4-5 years and on the whole I'm very pleased with it. I previously swapped between a 16-45 and 24-90. Overall I think the 17-70 has slightly better colour rendition than the 16-45, and I make use of the longer end quite a lot. I seem to get m...

43mm Ltd jammed.
Hi folks, I wanted to use my 43mm this evening and got it off the shelf to find that the focus ring is utterly stuck. The camera cannot focus it, I cannot focus it manually. I guess it is off for repair, but any guesses before I send it off? Any recommendations? I know the official repair p...

Have you tried manually moving the focus drive pin back and forth.

choice of four
I'd guessed that those shorter options (Pentax 16-45 / Sigma and Tamron 17-50) were not on the table ..? I've resisted them also as I'd ideally want to extend the range of my kit zoom with an even more versatile and higher quality choice. But then Philip, you're someone who chooses the 20-40! Th...

Wondering what the field of view of the DA lenses is on the K-1?
Will you be posting photos made with DA lenses in K1 crop mode? Thanks for your comments John. In K-1's crop mode they must surely be very similar to taking them on a K-5, K3 etc. All the full frame mode does on the K-1 is to force the camera to store the image from the whole sensor, saving the ed...
