I have taken the top cover of my K3 apart but the viewfinder adjustment gear pop out and I cant figure out what should be the correct max & min position.

Can someone kind enough to help me out by taking a picture of the adjustment dial at max position (say all the way clockwise) and at the min position (say all the way counter-clockwide) ?

Much appreciated.

Do you have any other card working in your k70 at all? Just try to isolate whether it is card or body problem.

I have the same problem and I also think it is the on-off control button, the metal contact has lost its strength/flexibility over time, I took mine apart (require taking the top off) and bend the metal contacts a bit and the problem go away.

I know the DAL 18-55 is cheap, but i have fungus developed in the internal lens assembly. I managed to clean the fungus but then discovered a few spots within the lens assembly in the picture.

Does anyone know how to further dissemble this?

I did this mod more than a year ago as well, just saw this and decided to take it out to play around. AF actually works with my K-01.

K-01 disassembly instructions here:

http://webpages.charter.net/n8nxf/Pentax%20K-01%20Disassembly%20Instructions.pdf

Just be extra careful on the last step with the wires, they are high voltage and can shock you badly. Again, pay attention to the flex cable between the top cover and the body. I broke mine so just to share my experience here.

I bought them locally for $3 each and have a few spares. I can send if you pay for postage and also cover my cost. PM me.

See the attached picture of what you need to do:

Please pay extra care so you DONT break this flex cable when opening up the camera:

Hey guys I would need to poke your brain.

I've got 2 copy of Vivitar Macro Focusing Teleconverters, they are identical model.

When I put them side by side, under a hanging lamp on the dinning table, the color reflection are very different.

There are multiple reflection of the hanging lamp on each lens, but on one there is a purple color but on the other there is blue...

I tried a few angles and the behavior is consistent.... what gives??

Is one better than the other? which one?
