Fujifilm MCEX - 11 Extension Tube

 I have just received my Fujifilm MCEX - 11 Extension Tube.

I'm no stranger to the world of macro photography having a pair of vintage Macro lenses in the shape of the Pentax M 100mm and 50mm F4.
I wanted to see how my Fuji 35mm f1.4 lens would work in conjunction with an extension tube. It makes sense if you want to travel light and only carry one lens, also auto focus is back in the game and all the EXIF data as well.

There are some third party tubes available through sellers on Ebay,  I have read some comments about the "pass through contacts" damaging the lens or camera and I'm so in love with this camera and lens I didn't want to risk it. The Genuine one was "on special" so the difference in price was only about A$40.
This one is made in China, the build quality is the same as my Fujinon 35mm lens, so, excellent.
I've only had a quick go with it and I’m not disappointed, the 35mm is still as crisp as ever and everything works fine, it mounts perfectly as you would expect.
The focus range is very small with the XF 35mm. Min = 5cm  Max = 10cm from the lens nose, that's it.
Just tried it with my 55mm f1.8 with M42 adapter and it works well Min = 15cm Max = 28cm.

It's not intended to replace a dedicated Macro lens, as a macro lens will focus "close" and all the way to infinity, so keep that in mind.

I think it's pretty good.

Edit: Dec 2016
I've been using the little flash unit that came with the XT1, in conjunction with the extension tube. It works really well, as this little spider demonstrates.

Pentax 100mm f4 Macro lens Review

Another great manual focal Pentax lens from thirty odd years ago. Many positive comments regarding this lens can be read over on the "Pentax Lens Forum"

Pentax 100mm f4 macro lens

This lens uses a "Heliar" optical design.

• Focal Length:     100mm
• Aperture Range: f4 thru f32 half stops thru to f22  6 blades
• Focus Travel:      350 degrees
• Close Focus:       45cm
• Filter threads:      49mm
• Weight;                370gm

Beautifully smooth focus ring, nicely damped, great lens.

This is a great lens if you like taking shots of insects. Its focal length allows a bit of clearance between you and your living subject, they tend to run or fly away given the chance.
Like its little brother the 50mm it exhibits no aberrations that I can see, no purple fringing no chromatic or general distortions. This lens at f4 does display a small amount of "Coma" at the edge of the frame, it disappears from f5.6 as shown in the picture below.

As well as being a close up lens it's also a 100mm telephoto, so if you have an "aps-c" sized sensor in your camera, you get a field of view equivalent to 150mm on "full frame".

Pentax M 50mm f4 Macro Lens Review

You can read about the Pentax 50mm f4 Macro lens on the "Pentax Lens Forum" , and It's well worth the read.
This lens is over 35 years old, and In my view, it's a little ripper.

Pentax 50mm f4 macro lens

It's a very simple lens in that it's based on the Zeiss "Tessar" optical design. Four elements in three groups. The Tessar design lends itself to a sharp and distortion free lens, but this comes at the expense of speed.
You won't find a really "fast" Tessar lens from any company, Zeiss made some at f2.8 actually millions of them. I don't call that fast, I'd like to try one though, think I will.

• Focal Length:    50mm
• Aperture range: f4 thru f32  5 blades  half stops up to f22
• Filter Threads:   49mm
• Weight:             169gm 
• Close Focus:     23.4cm
• Focus throw:     350 degrees approx

The Lens assembly is set so far back from the front you don't need a lens hood with this little fella either.

You might say "A bit slow at f4" but who cares, once you step outside into the sun you start at f4, or f8
Being wide open at f4 also allows for some nice "bokeh" as you can focus very close to your subject and have an "iris blade free" background blur.

The only down side I have found is at the far end of things, as you approach infinity the focus travel gets rather small, so nailing focus at that end takes a bit more patience.

As the saying goes "a picture is worth a thousand words" so some pictures.

One of those weeds at f4 and 

100% crop at the right.

Nice flower and

100% crop

As you can see very sharp, and as I believe also free from distortion. No only a great close up lens, but also great as a walk around lens as well.

The following two are straight from the camera, not cropped, just compressed a bit.

Probably f8.Focused on the motor.

Most likely f8
