<p>Is there a rough guide for the sharpest apertures on each of the Pentax 67 lenses ? I'd previously heard that as a general rule it was always wise to stop down one or two from the max which in this case would be f22->f11 ?</p>

<p>Hi all,<br>
I am a new Pentax 67 owner (that's the middle version, not the earlier 6x7 or later 67ii). I'm just starting to get familiar with the camera after making a decision to compliment my existing Nikon film cameras for landscape photography. Together with the body I bought the 55mm/f4 lens which I had read was one of the sharpest available for this camera.</p>
<p>I have a couple of questions which I will break up into seperate threads hopefully to make it easier for the right answers to find them...</p>
<p>So, my next question is regarding the sharpness/focussing. As my interest in using this camera is in landscape photography I would like to ensure that my technique is optimum for producing the maximum sharpness in my images. My camera is positioned atop a Gitzo 1257 tripod used in conjunction with a Markins M10 ballhead and a Markins damping plate. I have also removed the center column from the tripod and usually will hang my backpack from the remaining center hook. In addition I am using Mirror Lock Up and also a cable release...</p>
<p>Would there be any other steps required in order to get the maximum sharpness ? Are there special techniques for focussing (eg using hyperfocal distances) which would be beneficial in order to maximise sharpness all the way through from fore to back in the image ?</p>
<p>Any help would be appreciated !</p>

<p>Hi all,<br>

<p>I have a couple of questions which I will break up into seperate threads hopefully to make it easier for the right answers to find them...</p>
<p>So, my first question is regarding the viewfinder/focussing screen. I have noticed that it looks pretty dark especially when I compare it to my Nikon 35mm bodies (eg, F6). The central 'spot' or focussing area is not too bad but the rest of the viewfinder is dark enough to make focussing a little tricky especially in low-light landscape scenarios. Does anyone have any advice about that can be done about this ?</p>
<p>I have seen that it may be possible to change the focussing screen but the replacement product I have seen mentioned elsewhere does seem very expensive (USD 200+) so I would prefer a low cost solution if there is one out there ?</p>
<p>Thanks in advance,<br>

Hi All,
I've recently been asked to help take some photos at a wedding reception and a
reunion as a favour to some friends. For both events they want to capture some
nice portraits.
I haven't really done any serious portraits in the past so am now trying to get
some ideas about where to start. I'm hoping to buy a new lens this weekend for
my Nikon. I'm currently looking at the 70-200mm f2.8 VR lens which has been
highly recommended (albeit wallet unfriendly)...
I'm hoping to shoot all B&W film to get some more interesting shots and then
develop myself at home. Any printing I will get done externally if required.
I've developed a few B&W rolls at home and so am reasonably comfortable with
that part although I've not experimented too much with different
developers/strengths/times, etc.
So my questions are:
1) Is a 70-200mm f2.8 lens sufficient for this portrait work ?
2) What films are people using for B&W portrait work ? I know this is very
subjective but I'm just trying to get a few ideas for a number of possible
options with the characteristics of each
Any help would be appreciated

Hi,
Hope someone can help.
I've just invested in a dry cabinet to store my collection of slides. I also
bought some archival sleeves to store the slides. I think they are these:

But I'm not sure whether I should mount them before I put the slides into the
sleeves ? There is enough room for a mount and I do have some Gepe Anti-Newton
mounts which have glass on both sides.... But I seem to remember somewhere that
it may not be good to keep the slides in glass mounts for long periods due to
some corrosion issue ?
Any help would be appreciated.

Hi,
I would be interested in Feedback/Critiques/Ratings on the various
travel photographs I have assembled in my portfolio:

Let me know what you think. I always try and repay the favour for
people who have taken the time.
Thanks
Rick
Techniques for producing the sharpest images on a Pentax 67 ?
in Medium Format
Posted
<p>Thanks. Yes, I believe I have the latest generation of f4 55mm as it takes a 77mm thread and states 'SMC Pentax 67' on the lens (rather than 'SMC Pentax 6x7' as I believe the earlier model would show).</p>
<p>Actually I was thinking about a 45mm too as I'm kind of used to using a 17-35mm lens on my Nikon and hence the wider angle. Interesting that you mention the 45mm's that you owned were not too sharp as the reviews/ratings I have seen seem to suggest that it should be pretty sharp (eg, http://web.archive.org/web/20071111145755/http://members.aol.com/dcolucci/p67ss.htm)</p>
<p>With my tripod setup it works perfect on my 35mm Nikon gear with a reasonable weight on it. Even with a 70-300mm at 300mm the slides are near perfect tack sharp. So I'm hoping that it would also be sufficient for the P67 although I appreciate the mirror slap/shutter shake is definitely going to impact things...</p>
<p>If there were any problems inherent with this particular lens that I bought could that manifest itself as softness in the image ? I appreciate the chances of this issue may be small but just want to make myself 100% sure that I have 'maxxed out' my sharpness as much as I can...</p>
<p>Thanks again,<br>
Rick</p>
