.... and quick shift capability. :) please explain 'quick shift'? Lilly Lilly it means you don't have to put the camera body into manual focus if you choose to focus manually, you can leave the body set to auto focus. :wink:

.... and quick shift capability. :) please explain 'quick shift'? Lilly, your kit lens has Quick Shift (assuming it is not the L version). You let the body auto focus, and then you can change the focus by turning the focus ring yourself without having to switch to MF. Richard

Quick-Shift is only useful though if you turn off the function to auto-focus when you half-push the shutter button. Then you can manual-focus by turning the ring, or auto-focus by pressing the AF button.

I do it sometimes on general scenes, if you have something off centre in the foreground and want it to be in focus just half press the shutter to "lock on ", then recompose the shot and press!......Magic...lol I found out by accident! Ken

Macro Advice from the experts please!
Just came on this thread while researching some more info on quickshift focus on my 100mm macro. I tend to use more manual focus while taking macro snaps so was wondering if there is any other way or settings in the camera that can be tweaked so that I dont need to use the lever (AF.S, AF.C, MF) ...

Quick Shift enables use of manual focusing without switching the camera to MF. The practical benefit works like this. A half press on the shutter release will autofocus and lock the focus point. Maintain the pressure whilst tweaking the point of focus with the manual focusing ring. Fully press the s...

Amin, most/some users here have removed the autofocus from the release button and only use the AF button for autofocus. I also have it like that and leave the camera in autfocus but since it doesn't focus anymore while pressing the button it's like manual focus and if I do need autofocus I simply p...

18-55 II or 16-45?
Asked the same thing when I joined the forum. It was a toss up between the MKII, the 16-45mm and the Sigma 17-70mm macro. Bought the 16-45mm in the end but always wondered if I had done the wrong thing so when a 17-70mm came up a few weeks ago for a decent price I bought it. 17-70mm is going ba...

17-70mm is going back up for sale. Why? Never use it, or is there an issue?

Sigma 120-400 & EM 140 DG Ring Flash
It will be interesting to see how the 100-300+1.4xTC at 300m/f4 (=420/f5.6) compares to the 120-400 at 400/f5.6 Not sure how it will compare but I teamed up my Sigma 2X DG EX teleconverter with the Pentax F* 300mm f4.5 that I got from a member here last week for the first time today and I was quite ...

Front Focus Issue - Help Needed
Hello Everybody! I was trying to establish what is the focusing situation of my gear; I prepared the whole focussing chart and started testing the various lenses and 2 K10 bodies. Whilst almost all the lenses are doing well, and have an average Front Focus of 2mm +/-, I have a big issue with ...

Front Focus Issue - Help Needed
Nathan 2 things. 1) Its always the 50mm @1.4 that will show any FF/BF issue simply because of the DOF. All you lens might be FF at the same amount but without a 4mm DOF you simply wouldn't notice it....so to conclude its not necessarily the lens. 2) Are you doing your tests indoors using house ...

Ok fair enough. Assuming it is the lens, from posts I've seen on the pentaxforums site, k10ds can be upgraded to a newer AF system at pentax and have lens correction adjusted for that lens. You would have to send both bodies as well. OR..have chat with SRS as they have a 2ndhand 50mm (or di...
