John that is not what it says in the confusing blurb in the manual. I believe you have a choice of f stops and not just f 8 at 400 asa in green mode. I cant work out how or why though!

John

Hi

Sorry it is the AF160

I understand that green mode is from 1-4 metres and red a little further. I understand that for green mode the suggested f stop is f8. What I dont follow is whether I can use different F stops in green mode and if so how this works and effects the flash. Similarly I wonder how this works with red mode too?

I have read the instruction manuals for both the camera and the flash but am still struggling and wonder if someone can advise me?


I am not seeking to use the flash in manual mode but instead probably using green but perhaps red.


I think I am being told that if I use green I should set my aperture to f8 as I will be using a 400 iso film. I am presuming that this will work for all distances from 1 m to 4 m ?


What I can't understand is if I want to use a different aperture . The manual talks about being able to use two F stops in the green or red mode but I cannot understand how this works and which F stops they mean as the scale on the back of the flash has seven to choose from.


The scale on the back of the flash also seems to be at odds with the manual in that the correct setting for a shot using green mode, 2 m from the subject would involve an aperture of 16 and not 8 as the manual says.


Can anybody throw any light on this for me?


John.

I may have the answer. I was concerned as the camera was serviced within the last 6 months and so hoped for operator error as opposed to a return to the menders.

When I used the winder I purchased recently, that involved taking out a cap at the bottom of the camera and screwing it into the winder for safe keeping. When I took the winder off later, I didn't put the cap back and there is a big hole right into the bowels of the camera. It may or may not be this but it could well be. I have posted a link to a review where the reviewer highlights this as a potential problem.

I mention all this as it may help other people in due course, if not me.

Yes I am hoping for operator error. However, the negatives which were blank were adjoined, both sides by ones which were not so I deduce the camera was winding on. I am hoping Womble is right and when I get out with the camera I will make sure I stay within the 4sec on Auto ad see what happens

John

Thanks John

No but I will. Thanks

I am a bit perturbed though that if the camera says 4 but the film says 7.. Doesn't that make the camera way out or is this infact a massive advantage as opposed to disadvantage?

John

Thanks.

Thanks Womble and everyone

I wonder if anyone can advise with regard to another pentax LX problem I am having.


If I shoot with fresh batteries in manual mode 4 seconds shutter speed is 4 seconds. However, if I do it in Automatic it seems always longer, perhaps 6 or 7 seconds. I wondered whether this was actual not a fault but something to do with OFT although the shots were taken under controlled circumstances and I dont think that the light was changing.


I am hoping that the meter isnt playing up in auto and surely if it was it would play up in manual too?


Incidentally the AG13 batteries seem to drain very quickly after a couple of weeks or so and I fear the worse but wonder whether there are any better batteries I could be using?
