[pure-silver] Re: Yashica 124G (was Death Valley Days..... film problems)

Hi,
I squirted some Electrical Contact Cleaner under the closing knob and now it turns very easily but I have to apply pressure to the back to keep it closed so that the latch catches on the pin in the front of the camera and then turn the knob I haven't encountered this problem with my other Yashica- Mat models; just close the back, no effort required and turn the knob. 

Would you happen to know what the repairman did to solve the problem?

Cheers,
bogdan

My 124G (bought used, circa 1992) always offered terrific resistance when closing. Some years later, when it developed a another problem that I actually needed fixed, the repair guy fixed that, too. Ever since then, the locking knob has turned like butter. I don't know whether that has anything to do with your problem. I've never used 220 in mine. But difficulty turning it closed is an annoyance you can get fixed.

Hi all,

Nice to be back in a cooler climate, 80°F,  but Death Valley was an
extraordinary experience, photographically and otherwise.   Granted it
was hot, 120°F everyday, but manageable what with all the suggestions
from fellow members of this group.   Didn't even get a sun tan
although the tip of my nose was slightly reddish :) 
I spent last week recovery from the experience since I found it very
demanding physically and mentally.   Also developed all my film, a
mixture of  Tri-x 320 (220 and 120) shot at 200iso, developed in D-76
1:1 and AgfaPan 25 shot at 25 iso and developed in Rodinal 1:100. Next week, I do the contacts and then start editing in preparation 
for printing.

I have one question concerning a problem that occurred with the 220
Tri-x.  First off, I was shooting the 220 in a Yashica-Mat 124G.  What
a relief not to have to change rolls after 12 exposures. Anyway, when I developed the film , I noticed that all the 220 rolls had a 
light streak  that was exactly in the space between the images on the
negative.  None of the images were affected and this did not happen to
the rolls of 120 Tri-X nor the 2 rolls of APX 25 that went through the
124G.  If you look at the back of the camera, the film advances from
the bottom to the top take-up spool and the images numbers are on the
left side.  The streaks originate on the right side, where the film
advance crank is. What do the streaks look like? they vary in length, from the thickness of the edge of the film (1-2mm) to 2-3 cm, and are shaped 
like a dagger, thick at the edge of the film and tapering off to a
point as the streak goes down the space between images.  In two cases,
the streak is wide enough that it  impinges on the images (1mm)   but
nothing that a little cropping can't fix.
Several observations: 
This only happened with the 220 film which doesn't have a paper
backing the length of the 24 images.  The 120 film, (Tri-x and APX)
with a paper backing,  doesn't have this problem which leads me to
consider that perhaps there is a light leak on the right side of the
camera back.  Because of the paper backing, the 120 film of protected
from the light leak; the 220 has no backing and receives the light
leak.

What I find curious is that the light leak is very regular; it only
manifests itself, in various lengths, in the space between the images,
so the leak is either at the top or bottom of the back, on the right
side, on the side of the crank. 
I did notice that when I close the camera back, I have to put extra
pressure on the right side in order to close the camera back and
keeping applying pressure in order to  turn the wheel  at the bottom
of the camera to lock the back in place.  Maybe the problem is
there????  Even when locked, there is something that might be  pushing
the right corner away from the front of the camera, enough to cause
that slight light leak.  Do light seals have to be changed???

Anyway, the images aren't affected but it is a nuisance.

Anybody have any ideas as to what is going on to cause this
phenomenon.  Anybody with a Yashica-Mat 124G ever have this problem
using 220 film.  If you have a 124G, does the back close easily?

Any input would be appreciated, as I want to bring the 124G with me to
Anza Borrego when I go there in August.

Thanks in advance!

Cheers from rainy Montreal,
Bogdan
