Hello Billk and tduell,

Fellow Victorian here. I am interested in purchasing the Pentax 1.4x TC.

I wish to use it primarily with K1 and 150-450 for wildlife, being aware of the vignetting problem.

But cannot find a source in Australia. Any suggestions?

Thanks Neil.

Hand held setting for wildlife on 150-450 on K-3

Thanks for all your suggestions. It seems that technique is my main issue here.


I already use back button focusing - but may need to refine that too.


The suggestion to use electronic shutter - is that only available on the K-1?




It seems that a number of Pentaxians have the 1.4TC on the 150-450. So I imagine that must exacerbate the problem somewhat. I will have to perfect my skills before buying the TC.

Hello All,
I need some practical advice on settings for Pentax 150-450 lens on a K-3 for wildlife shooting handheld. Initial shots were very soft - very disappointing.


Have used a Sigma IS 150-500 in past with much more acceptable results.


Is it a stabilization issue. Is the K-3 in-body stabilizer not up to the task?


Is it camera or lens settings? Both? Neither? Technique?


Feel that I have wasted my money. HELP!!

A very crisp morning on the South Island near Twizell. Cold but well worth the effort.

Just a further question to photoptimist.


Does that mean that if I used 1/50th sec exposure with 50Hzmains I should be OK??

Yes it was Adam.


A small amount of natural (sun) light, but predominately tri-phosphor fluorescents.


What does rolling shutter refer to? I haven't heard that term before?

Why did it occur with the pixel shift image but not the one without?

I am totally puzzled with this issue that seem to occur with latest upgrade of LightRoom CC and DCU5.


Has horizontal pale yellow bands clearly noticeable across the image. Attached are 2 sequential images, one with (PEN2163) and the other without (PEN2164) Pixel Shift.


I have not been able to find any reference anywhere to this phenomenon anywhere on the web.


Any clues??


Thanks.

Please note that the images should be in the reverse order to that noted in the post. 2163 WITHOUT and 2164 WITH pixel shift.


Regards.

Fine Focus Adjustment on K1

The 24-70 is new to me. Just purchased second-hand for use on the K1. I have just tried the Dot Tune method listed by deepbluish, but couldn't get the lens to misbehave as in my previous test. Most strange.


I guess that I just have to keep testing to determine the situation(s) when it is not focusing properly. Seems a bit random at present.

Tested in controlled conditions on a tripod using remote shutter release. Tested at 24 and 70mm, F2.8 and F8. Using a proper printed target set at 45 degrees to lens. About 1.5m away.

Have a problem with front focusing on a Sigma 24-70mm lens. Tried to use the AF Fine Adjustment function but could see no difference. Any suggestions?


Also noticed in the tutorial on the use of 3rd party calibration tools that it is not clear whether the AF Adjustment function alters phase detect AF, contrast detect AF or both. Any thoughts?
