[If I have misunderstood the problem, and am teaching grandma to suck eggs, please ignore what is written below.]
If you don't adjust the shutter speed the pictures will be under-exposed.
Let us for the moment assume there is a "correct exposure" for an image. Lets say you have 100 ISO film loaded and the aperture set to f/8. The camera will choose the correct shutter speed for that combination to give you a correct exposure. For the moment, let's assume that is 1/125. So:
ISO 100 f/8 1/125
In terms of exposure this is the same as
ISO 100, f/11, 1/60
ISO 100, f/5.6, 1/250
and so on. With the ME you load your film (ISO 100) and pick an aperture on your lens (f/ and the camera sets the shutter speed which is indicated in the viewfinder with an LED.
Now let us say the light is dim, and with ISO 100 film at f/8 the camera is giving us a shutter speed of 1/30, which is the same as:
ISO 100, f/11, 1/15
ISO 100, f/5.6, 1/60
and so on. Assuming you have a 50mm lens, you want to keep the shutter speed at 1/60 or above, you need to open up the lens (make the aperture larger) until you do. In this case pick f/5.6.
If the light is even worse than that, you might find that you get to a maximum aperture, say f/1.7, and still not be able to have a shutter speed of 1/60 or faster. In that case you have a choice:
a) use a tripod or find some other way to brace/support the camera
b) use a flash
c) if you don't already have some film loaded, use a faster film.
You cannot change the ISO in the middle of a roll. One of the advantages of digital is being able to change ISO on the fly. Alternatively, given how cheap film bodies are these days, have several bodies with different types of film loaded.
Hope this helps.

The big old A*85/1.4 on the front rather counteracts the sleekness of it though! (Me? Jealous? Never...)The FA-2 does have a lovely, sleek look....

Aww thanks. Nice of you to say so. womble wrote:

Hi Kris, you're one of the more enthusiastic members of PF and here, and a huge fan of K glass. I think it's fitting that you won the prize of a camera that makes it easier to use these older lenses.I didn't want the premium kit! I have no use for a grip. It was a prize draw, so nothing more than dumb luck.
Well done.
The only slightly frustrating thing is my ever growing film stash... I just won another five rolls of Tri-X in 120!

The FA-2 is much less common hence the higher price. I like the look though, it gives the LX a sleek Spotmatic-without-the-cold-shoe sort of look.
Do you have the FB-1/FC-1 combo? That's a nice set-up too but not very "packable" so I don't use it very often.

You'll be disappointed with the 16-50 as nothing can seemingly fix that things AF speed, other than a redesign with a PLM or DC motor.
This is in the works, so to speak. Let's hope it doesn't take as long as the K-3iii. I've yet to find a "standard zoom" I'm happy with, and tend to stick to my primes in that range. I was hoping it might get released at the same time as the camera, but hey ho.You'll be disappointed with the 16-50 as nothing can seemingly fix that things AF speed, other than a redesign with a PLM or DC motor.

The 50-135 doesn't feel any faster (although I'll go out one day with both the K-3 and K-3iii bodies and try it out). BUT, it locks on better (less hunting) and the focus point adjustment with the joystick is a breeze (when I remember, but that's my fault not the camera's).Tyr wrote:
AF accuracy seems spot on even in poor light. AF speed is as good as my lenses will allow. AF hunting is negligible to non existent.
I see from your Flickr you have the 16-50mm & 50-135mm, how do you find the autofocus speed on them as I always thought they were slow to get where they needed to on previous bodies plus they tended to hunt quite a bit. Fantastic quality though so I have kept mine for when I decide the K-3 III price is right for me.AF accuracy seems spot on even in poor light. AF speed is as good as my lenses will allow.

Largely I have been using my shift lens and the FA31 so far. The focusing seems pretty good to me. I'm planning to take the 50-135 to the allotment and try to photograph my chickens... they move fast enough!

Phil on the US Fora (gofour3) has one he regularly uses. As much as I'd like one, they are just too expensive for me. Even the improved grip sells for a pretty penny.I keep coming across references th the Pentax LX Millenium camera.

Thanks Kris! I probably paid a bit too much for the LX, but when calculating in the value of FA-1W (that was on the camera), I feel slightly better about the purchase
I have adjusted the diopter screw one time with a small flat screwdriver, but for the future I will look for something plastic for the job.
I have been lusting for the LX for many years, but have been telling myself that the KX and MX is all I need. While this is true (all I need), the LX feels like a completely new generation SLR, probably because of the "A" feature and the possibility of using many different viewfinders and focussing screens. I am looking very much forward to loading my first film in the LX
As much as I like the MX, the LX is my favourite SLR. I try to rotate round the various bodies I have, but whenever I travel I take the LX and an MX. Enjoy. It is a lovely camera.Thanks Kris!

I'd add a bit to Lenny's estimate for the FA-1W. In good condition I'd expect not to get change out of £100. The special tool for adjusting the dioptre is basically a plastic screw-driver...
I love the look of the FA-2, but the FA-1W is the more practical choice for my eyes.

My bench image that won a prize in the Jan AW comp was taken on the 30. The Lomochrome purple version of the same photo got an honourable mention this evening.

PS Lovely set!
