This ad-free website's biggest source of support is when you use those or any of these links to my personally-approved sources when you get anything, regardless of the country in which you live. Use only the approved sources I use myself for the best prices, service, return policies and selection. Thanks for helping me help you! Ken.

I buy only from these approved sources. I can't vouch for ads below.

Extension tubes are empty tubes we can attach between our lens and camera body to extend the lens farther from our film or image sensor.

This lets us focus much more closely for macro use, but also reduces the effective exposure due to the extra distance.

TTL meters like the PME series compensate automatically, but you may have to apply manual exposure compensation when used with external exposure meters.

The lens focuses more closely with the tube in place, but of course no longer can focus to infinity.

They sell for about $25 used at this link directly to them at eBay. Be sure to read How to Win at eBay so you can pay this little.

 

Compatibility

Top   Introduction   Compatibility   Chronology & Part Numbers   Usage   Distance Table

All the newer tubes work with older equipment, as the ability to work with newer focal-plane or electronic cameras.

Older tubes used on newer cameras may lose electronic communication, or not mount to the 2000 & 200 series cameras.

Everything old and new works great with the original 500, 501 and 503 series.

 

Chronology & Part Numbers

Top   Introduction   Compatibility   Chronology & Part Numbers   Usage   Distance Table

 

1957 ~ 1982: Fluted Grips (500 series)

These first series of tubes have fluted grips matching the C lenses. These are what I show at the top.

They originally came in only 21mm and 55mm lengths in 1957, and 10mm was added in 1973.

These work with all traditional Hasselblads, but not with any focal plane models (2000 and 200 series) because they interfere with those cameras' shutter speed ring.

 

1957 ~ 1982

21mm (TIMDC or 40010) and 55mm (TIMBC or 40029)

 

1973 ~ 1982

10mm (40363)

 

1977 ~ 1991: Fine Milled Grips (adds FC & F compatibility)

These tubes have slightly different barrels so that they can clear the shutter-speed rings of the 2000 and 200 series focal-plane shutter cameras.

 

1977 ~ 1991

16mm (40541)

32mm (40568)

 

1981 ~ 1991

8mm (40649; too short to work with the focal-plane cameras)

56mm (40657)

 

1991 ~ 2013: Smooth Barrels (adds TCC & E compatibility)

This series has electronic contacts for use with the TCC cameras and FE and CFE lenses.

They also work on the older cameras and with older lenses.

The model numbers changed in 1994 with the 205 FE, but seem like the same tubes.

 

1991 ~ 1994

16mm TCC (40543)

32mm TCC (40570)

56mm TCC (40659)

 

1994 ~ 2013

16mm E (40654)

32mm E (40655)

56mm E (40656)

 

Usage

Top   Introduction   Compatibility   Chronology & Part Numbers   Usage   Distance Table

To keep your cameras and lenses in synchronization and prevent jams,

1.) Be sure lens and camera are charged (film advanced).

2.) Mount the tube to the camera first, and then mount the lens to the tube.

2a.) If using more than one tube, attach one tube to the camera first, then stack the next tube on the first tube, and put the lens on last.

3.) To remove, be sure everything is charged (film advanced and shutter cocked).

4.) Pull the lens first, then each tube in sequence working down towards the camera.

If you remove them in the wrong order, you'll probably fire the lens and have to recock it off the camera — otherwise you won't be able to mount it again.

 

Distance Table

Top   Introduction   Compatibility   Chronology & Part Numbers   Usage   Distance Table

This tabulates the close-focus distance with lens set to infinity (they will focus closer as lens is focussed closer).

These are simple calculations presuming a thin lens of the indicated focal length; I didn't calculate these for real lenses with their principal points separated.

This is the distance from the subject to the image plane. The distance to the front of the lens will of course be much closer since the front of the lens is ahead of the image plane.

* doesn't work; focuses so close that it focuses inside the lens!

** the 135mm is a short mount that must be used on a bellows, so these calculations are what happens if you add the tube to a bellows already focussed at infinity.

Help Me Help You

I support my growing family through this website, as crazy as it might seem.

The biggest help is when you use any of these links when you get anything.
