Re: Naive question, viewfinder magnification

Unfortunately this is a case of a vicious circle: a viewfinder with bigger 
magnification gives you - yes, you've guessed it - bigger image in the finder, but 
that's why it is hard to see the whole image, including exposure data outside the 
image 
area, at a glance, especially for those wearing eyeglasses. Smaller viewfinder 
magnification gives you the so-called "high viewpoint finder", which makes it easier 
to 
see the whole image and exposure information even with your eye detached form the 
eyepiece bit the image is smaller and thus manual focusing is more difficult. Numerous 
AF cameras have a smaller magnification relying on the fact that AF will do the job 
for 
you and your task is only to compose and see everything at a glance. Having high image 
magnification and full picture of the image plus exposure data is a contradiction in 
itself. Your MX finder makes manual focusing a snap; with MZ-5N the priority is on 
ability to see everything in the finder at a glance even when you are wearing 
eyeglasses.

Actually, the ME is the highest, at .98x verses .97x for the MX.  However,
the ME's focus srceen is optimized for 
fast lenses, a F4 zoom on the ME can be a challenge.  But a nice 50mm F1.4
on the ME is a great combo.

I have found that the ZX-M is easiest to focus using the Matte part of the
screen anyway, I only use the center aids generally with longer lenses.
It's also the easiest when it comes to focusing slow lenses too, for fast
lenses I'd rather have a KX or the ME.

Yeap :(  Most AF camera users don't give a darn about manual lenses, and
just want a bright image to know what the camera is pointed at,
unfortunently.  (I'm not talking about most AF camera using list members here)

There is a simular finder for the LX too.

H.  "Action finder" reminds me of that door you open on the top
cover of a Yashicamat to give you a direct viewfinder.  At least it's
distortion-free and, with relevance to this topic, has 1.0x
magnification.  Pity you get parallax error...

Incidentally, the Leica 0-Series has such a viewfinder too.

AFAIK, MX has the highest magnificantion of all Pentax K mount bodies. I 
have had MX, LX, Super A/Program, P50, MZ-M and Z-1p over the years. I was 
amazed by how difficult to focus with the MZ-M due to the low 
magnificantion, because afterall, it's a manual focus body where good 
quality viewfinder is essential IMO.

I has been wondering the same too. Nikon made something called action finder 
for their F bodies so my only conclusion is cost cutting.

Naive question, viewfinder magnification

2001-06-25 Thread Francis Tang

I was just wondering, what's the significance of viewfinder magnification?  I know 
that since I am used to my MX and ME Supers, I found it quite hard to manually focus 
on my friend's MZ-5n.  So my initial thought was that the bigger the better.  But then 
I noticed that the LX officially has a smaller magnification than the MX.  In fact, 
all Pentax cameras have smaller magnification than the MX.  So what's up?

Incidentally, according to the brochures on the Pentax USA website, the MZ-S has a 
viewfinder magnification of 0.75x, where as that of the MZ-5n is 0.8x.

I've heard people complain that they can't see all of the viewfinder in the MX, and I 
know I have to press the camera hard into my face so that I can see all of it.  But 
why can't Pentax keep the same viewfinder magnification on the MX and just make the 
rear window bigger?  Am I just being too naive here?
