Question about Mamiya Macro 140mm f/4.5 L-A for RZ67

1 Answer

How do you use this particular lens? as it has a lot of different scales for different distances and also the floating element. I was told when you focus you check the film to lens distance, that is the distance to the camera,s film plane, check this and r-e adjust this setting on the lens to get the correct focus. Can somebody explain in more detail please. Many thanks

Does distance show kilometers or miles?


On a digital display the default in U.S. is miles. Refer to your owner's manual or call dealer if you need to change it. A km is .6 of a mile, so just drive about 10 blocks (around a mile). If the odometer registers around 1 unit more it's probably miles, if it says close to 2 then it's probably km.

There used to be enough steam to froth milk for 2 cups of coffee, now I have to turn the knob off, to let the machine build up steam 3 times too get enough froth for 1 cup of coffee.


This a
clear problem from scale builds up in the boiler. The scale layer is acting as
an insulation layer which is reducing the efficiency of the heating element to
the boiler and also reducing the water capacity thus also the steam production
capacity.



So you
should first try to de-scale your machine three four times with intervals of
three days from each de-scale. Try also to perform the de-scale very slowly
like when you will flash the water solution from the water reservoir take about
30 minutes why drawing a coffee cup every five minutes. With this way you have
very good chance to remove a lot of scale and you machine heating efficiency to
be increased. If after the above procedure you have no difference then you need
a new boiler which is one unit with elements and sensor.



Here below we
have a link with more information for your machine which can help you.

Focusing a mamiya k/l lens.how do i use the floating element ring? thank's


Step A. Set the floating element ring to its' infinity position (if you are using extension tubes, this will vary and you must set according to the tubes).
Step B. Focus the camera on your subject.
Step C. Look at the bellows scale on the camera body (it will generally range from 0-40) Important: Don't read the scale akin to the lens you are using. This will make perfect sense, when you examine the bellows. Mentally record this number.
Step D. Adjust the floating element ring to the recorded number.
Step E. Leave the ring on this new setting and re-focus the camera on your subject.
Step F. Make sure the dark slide is removed and capture your photograph. :)
- That's it mate. Not so foreboding, when you

I have a Hobart modle LXih that leaks from near the top on right rear There is a unit that has a small hose and two larger ones


Sounds like you're referring to the vacuum breaker. It's very easy and cheap to rebuild, if it'll come apart - sometimes they're very difficult to unscrew the top and the whole vacuum breaker must be replaced.

Obtain a rebuild kit for the vacuum breaker from Hobart (about $5). Remove the screw from the top of the vacuum breaker and take off the chrome cap. Use a cresent wrench or channel lock pliers to remove the now accessible upper section of the vacuum breaker. Clean all scale from the brass piece you removed, particularly from the center pin and the surface at the bottom of the removed brass piece, where the threads start. This surface is the surface where the moving float's rubber seal will come up to and form a watertight seal. If you're unsure what surface I'm referring to, place the white plastic float onto the removed brass piece and take note of there the orange seal of the float contacts the brass - this is what must be clean, straight and flat to make a good seal with the new float. The center pin must be clean so that the float easily moves up and down on the pin without binding. Also clean all scale from inside the body of the vacuum breaker, although not as critical as long as the float will move freely inside the body of the vacuum breaker. Once it is cleaned, reassemble and you're done.

P.S. it's possible you may be able to stop the leak simply by disassembling and cleaning the scale as described above, but considering the cost of the rebuild kit, you should replace the float from the rebuild kit as the float's seal shrinks over time, which may in fact be your problem instead of scale deposits, or both.

1. HOW TO READ SCALING OF SCOPE.? 2. What is


You have not provided enough information for us to help you. What type of rifle? What do you mean by scaling?

With the scope on 3 power you should be able to sight it in at 25 meters. Going to a higher magnification may cause blurring at that distance.

You also may have mounting problems that are causing the scope to move around when you shoot. Your rifle may be fine.

New user and I lost my manual to use.


Can't help you the the manual - Canon obviously doesn't make them available on their website.
However, you can find a very detailed review here, which should answer all your questions.

The meter window is just a distance scale, which shows to which distance the lens is currently focused. For normal auto-focus operation you won't need it (you can use it as a rangefinder, to estimate the distance to an object, though) - it may be useful for approximately setting up manual focus in low light situations.

Side out of image


I'm assuming in what follows that you've tried other lenses and only get the problem with this one lens. If you haven't, then it's essential to do this first unless the lens is obviously the problem. If it happens with other lenses then you have a damaged image sensor mounting within the camera body which will need professional attention.

This is a common problem on this particular lens. Normally it's due to the front element of the lens being slightly skewed on the lens barrel and most commonly occurs after the lens has been dropped.

Turn your lens to manual focus and focus to the shortest distance. Set the lens upright on a table and carefully view all around, if the problem is the front element it will lean slightly to one side like a miniature leaning tower of Pisa. If it doesn't, then check again with greater precision using a ruler to measure the distance s between the lens barrel and the focussing ring and a number of opposite points around the circumference. If they're anything but identical then the lens is skewed. If they are identical then the skewed element is buried deep inside the lens and will need professional repair as it's most likely a fault with the moving element used for image stabilisation.

If the tests confirm that the front element is skewed then if you're really careful and lucky you can often jiggle the front element using a firm twisting action back into place. It does take a bit of judiciously applied brute force and if unsuccessful you can make the problem worse, but either way if you don't try then the lens needs professional repair and new internal parts.

I've had this problem on about one of these lenses every month or so for the last year. The brute force repair works in about half the lenses I try it on and normally lasts. On the others a strip down repair usually shows the same range of broken/worn parts as I find on those lenses which clearly are too far gone to attempt the brute force method.

The difference is cost: the brute force repair costs nothing. The proper repair is often economically unviable as it often costs 50% to 70% of the cost of a brand new lens with a warranty.

Distance scale does not move on canon efs 17-85mm lens


Yes, this is normal. Some zoom-lenses adjust the focus when zooming, to always keep the subject in focus. Those tends to be the more expensive lenses.
So you don't have to worry, nothing is wrong with your lens.
