| Pros: | Build quality, versatility, lightweight. | | Cons: | | |
I have two sets. They work very well for macro work and for shortening MFD on longer lenses. They are light and easy to use if you know what you're doing. The 135/4 macro needs a lot of extension since it only goes to 1:3.2 without extension tubes, unlike the 100 mm which goes to 1:1 with the dedicated life size converter, neither of which I've had the privilege to use. Refer to the extension tube manual for the magnification and falloff compensation required.

| Pros: | Design, weight, ease of use. | | Cons: | Not for all 67 lenses. | |
For the past year, I have been moving to 67 lenses for my 645Z. With several, my 200 and 300 for example, minimum focal distance is substantial. Using the extension tubes lowers MFD. I have more testing to do but so far I am very pleased. A couple of comments -
They aren't always easy to use with the 645Z. I have to take off the lens, remove the adapter (6x7 to 645) and then add the adapter to the extension I am using and then... You get the picture.
Still excellent quality. Mine is in mint condition.

| Pros: | Well built and easy to use. | | Cons: | You have to use stopped down metering with the TTL/AE prisms. | |
This “inner” bayonet extension tube set comprises three tubes:
No. 1 - Length14mm (75g)
No. 2 - Length 28mm (90g)
No. 3 - Length 56mm (125g)
They can be used separately or in combination on any 6x7 lens with the inner bayonet mount, excluding the 35mm fish-eye. There is a separate outer bayonet mount set (23mm & 46mm) for the older 6x7 Takumar 400mm, 600mm, 800mm and 1000mm Reflex lenses.
For macro work generally a lens with a shorter focal length will give you the higher magnification. (The 45mm f/4 will get 2.27x magnification using all three tubes.)
The tubes also work well with telephoto lenses to get a shorter minimum focusing distance.
This extension tube set is very well built and easy to use and comes with a leather case.
The tubes will let you focus with the lens DOF lever in the “AUTO” position. However please note the following if using a 6x7/67/67II camera and a TTL/AE metered prism:
YOU MUST SET THE LENS DOF PREVIEW LEVER TO “MAN” TO GET A METER READING. THE 6X7/67 TTL OR 67II AE METERS WILL NOT GIVE A READING IF THE DOF LEVER IS IN “AUTO”. IF YOU ARE USING APERTURE PRIORITY ON THE 67II/AE YOU MUST LEAVE THE LEVER IN THE “MAN” POSITION WHEN YOU PRESS THE SHUTTER. THE AE METER WILL DEFAULT TO CENTRE-WEIGHTED METERING WHEN USING AN EXTENSION TUBE.
Price: The price I paid is for an EXC+ set with case.
