Need help to focus on M6


meng8123

Recommended Posts

Pete, Im a bit confused.

Mine is a current, I dont have an M6, so maybe there is something in their viewfinder/rangefinder arrangements I dont understand.

On my viewfinder Ive never found it too bright to focus properly, and I cant think of very many places brighter than some Ive been to, or summer here.

I take it for some reason one bright overpowers the other so you cant see to patch properly, but is it possible one is gunked up or coatings delaminating or something or is it just a featurefault of the M6 design/materials?

Ive heard of the flare problem.

 

Ps ... Maybe mine has been pre gunked or I downloaded it somewhere and never needs a shade:rolleyes:?

Hi, I am not sure if what I did wrong but when I try to focus M6 under sunlight or even under light, I can't really focus because the focus screen was too bright. any tip or thought on it please? thank you

 

In case you are referring to the well known rangefinder flare problem described here , you can get an upgrade.

 

I had both of my M6s upgraded to the MP viewfinder and am happy ever since.

They removed optical parts part way through the M4-2 production run, and subsequently enhanced (put the parts back and hard coated) part may through the M7 run.

 

It does annoy some people, when it is bad I scale focus, it can annoy during a gig if a profile light is in the wrong place.

 

Cheaper to get an earlier camera instead, if it is to annoying, as Solms will want and arm and leg.

According to Leica sources, the reason for the whiteout of the rangefinder patch

in late M-4Ps was the switch from a flat mirror (for brightline illumination) to

a parabolic one to improve brightline illumination.

 

In case of the M7 this problem was only partly reduced by introducing a second

reflective surface inside the rangefinder.

 

(this info was retrieved from another forum)

 

To my knowledge, with introduction of the MP, a rangefinder with an extra lens

has been introduced, which reduced the flare problem even further, if not completely.

Hi Juergen

 

Thanks

 

Good thing it had an En translation, I'd have struggled with my holiday Ge...

 

But that does not explain why my M4-2's and M6 are different, Unless the late M4-2 finders were the same as the late M4-P finders. It may be that the mirror and the 'condenser' are the same thing, merely that Leica ran dissimilar production processes...

 

I'll have to try all three cameras together again...

 

Changing the subject just a little when my M4 went for a general service (by 3rd party service person) for a shutter ribbon, it reappeared with a caveat that they had also enhanced the finder gratis, it was/is not detectably different from the early M4-2 finder.

 

I've tried a MP finder in bad light and it did not seem detectably different from the early non coated finders.

Hi Juergen

 

Leica FAQ — RF patch flare

 

I don't think we are off topic too much... but it does not seem to bother me, certainly not enough to send a body that it not broke for a trip to repair person.

The mask and the condenser lens mentioned in the document your link is pointing to are not the only parts used for the RF upgrade.

According to the invoices I got from Leica for upgrading my two M6s, they also replaced two plain windows with two coated ones.

Happens if there is a light source upper right corner. Twist the camera 90 deg, focus and recompose.

 

I have had this happen one time in thirty years with my original M6.

 

Or you can spend a ton of money and get a new RF put in. Not worth it in my opinion.

 

Earlier and later models did not have the problem.

 

As far a frameline illumination goes, sucks compared to M3 and M2 M4 and MP. A condenser lens was removed as a cost reduction pure and simple.

 

My M2R and M2 are my favorite cameras. MP will not accept the brass film cassettes so my two M6`s are the last I bought.

Rob,

 

I only have an MP so I've never seen this flare either. But I agree that if you're going to find it anywhere then summer in Oz is that place.:cool:

Hi Peter

 

Organise another outing and you can borrow a M4-2 or M6 to go with your out of fashion jeans.

 

Noel

Thank you, Noel. What is this "fashion" thing of which you are so knowledgeable?:confused:

 

Form Follows Function!

 

Pete.:p

White flares are out, then? Ah, the '70s...

 

One other tip is to make sure your eye is centered on the finder. This helps minimize the RF patch whiting out. Straight lines, vertical or horizontal, are a good target to focus on.

 

RF focusing can sometimes be tricky in very bright light but I still find it more precise than AF.
