Hello.

I've got a few questions on Ikonta disassembly.

First is: how do you remove the winding knob? It has a screw at the

top that doesn't seem to want to move. I don't want to force it and

I suspect that the pins that hold the 'wings' on top of the winding

knob is actually a single pin that goes through the screw itself and

I need to remove the pin first.

Second: middle element of the lens assembly. how do you remove it

from the shutter? rear and the front unscrewed quite easily...

Third, the bellows. It seemed that the bellows where attached to the

back of the lens with just a threaded ring and no glue. Was there

supposed to be glue and did it just dry out?

Thank you.

could someone please help me determine criteria for selecting an on

camera flash for 1. weddings, 2. 'do-it-all' 'go-anywhere' flash?

my experience is limited to using flash in a studio environment (and

some location work but using studio flashes as well).

how important is motor/extended zoom on 70MZ-5? Thyristor light

control - would it be an external light sensor on 60CT-4 as opposite

to using TTL? Guide numbers for both flashes are specified at

different focal lengths (www.metz.de) but it seems that 60CT-4 is

more powerfull (guide number for 70MZ-5 is 50 at 50mm and for 60CT-4

is 60 at 35mm).

70MZ-5 seems to have more nice features than 60 (flash bracketing,

slave function, modeling light etc...) - how often do you WANT to

use those features during, lets say, average wedding shoot?

i'm curious about possibility of using both flashes with Canon's EOS-

1 and 5 (my main camera is Bronica ETRSi).

and finally, can you use same powerpack with both flashes and which

combination will give me more shots per battery?

which flash would you prefer is the price was the same (i believe it

is almost the same)?

thank you.

i'm having problems attaching/using my NPC polaroid back for ETRSi.

very seldom i'm able to adjust the screw on the back to be able to

attach the back to the camera, wind the crank and release the

shutter. usually it takes about 10 minutes of fiddling with the

screw before i can get the back on the camera and than crank

wouldn't wind or shutter wouldn't work. Most annoying case if i can

get the back on, wind the crank, release the shutter and then I

won't be able to wind the crank again.

the camera is set in multiple exposures mode according to the manual.

when the back works, the screw is almost all the way out and some

adjustments (1/8 of the turn in some direction) actually make it

fall out.

i wonder if my problems related to the fact that the screw

is not secure enough and some shaking or releasing a shutter shifts

it so the crank wouldn't work? is it possible and do i need a longer

screw? what am i doing wrong? does Bronica's own polaroind back has

this pesky adjustable screw or is it the same pain in the neck?

thank you.
