Comment by neill posted on K7- shutter speed in manual mode at 19/04/2010 - 19:19
I would like to propose to the forum that new topics be placed at the head of the relevant subsection.
For example, " I've got a K7 to play with for 2 weeks" is hardly hot news now yet it has occupied second place in the digital SLR section ever since it was posted.
Its time to move on.
So lets have the latest topics a the top and save unnecessary scrolling-life's too short!!
Thoughts please Mr Moderator et al.

I use a 100mm DA lens, originally with the af 140C using the rings.
I was thus able to get closer to the subject.
The coupling tube increases the flash -sensor distance by the length of the tube (approx. 6cm)
Since the purpose of ring flash is for close up work, I just wonder in terms of physics and optics, what benefit the tube is giving over and above a coupling ring? as I now need to increase the aperture by a stop to compensate.

I have just uprgraded from the 140c to the 160c.
The 160c comes with a tube attachment for the macro lenses ( in my case the 100mm), as well as as a set of adapter rings.
The tube attachment substantially increases the minimum distance between lens and subject, thus reducing the maximum magnification.
Does the tube have a particularly necessary function in relation to the new flash, or can I use the adapter rings, as per my old ringflash?
This is important as I need to get close up to my subject (clinical dental photography)
Thanking you
Neil

I could not select the full shutter speed range- it kept scrolling around three values.
I returned the camera to SRS and they just updated the firmware and returned the camera within 24hrs!
I was extremely impressed with that bit.
If my memory is correct, Chris advised me that all the problems relating to K7's ( 7 or 8 units) that have been returned to them, have been sorted with a firmware upgrade
Had Pentax fully listed the fixes that the firmware upgrades address, it would have saved me a lot of aggrevation and kept the swear box depleted.
Hope that this of some help

Both my Pentax 300mm and 60-250mm lenses come with an attached tripod mount.
The mount has a standard tripod thread and a slightly smaller plain hole, presumably to take an anti-rotational spigot which attaches to a tripod plate.
My Manfrotto plate also has a spigot adapter ( with a small plastic spigot which pushes in) but it does not align with the lens recess when the lens is mounted on the plate.
a. Is there an industry standard for such attachments?
b. How do I address the problem?
Thank you in advance for any advice received on this topic.

I am using the latest firmware on my K7 although I have had the same problem with all firmware versions.
I have noteiced that when in manual mode i sometimes find that for a given aperture, I do not have full control over the shutter speed. I have shutter speed selected on the front wheel and aperture control on the rear wheel.
When scrolling the shuter wheel, speeds keep cycling over a narrow range, usually the very fast speeds.
I cannot get my head around this.
I did in fact return the camera to SRS and they just just loaded the latest firmware at the time.
Has anybody had this problem who can suggest something?
Thanks
Neil
