I was having trouble understanding how to focus with my new extension tubes until Isaw this video. Great example showing what it looks like in the view finder and then your set up. Helped me out a lot. Thanks!

Hi, new to photography. I see the depth of field is very small, but does it change it you set a closest aperture, or it is a fixed depth of field?

Informative video, but one error in terminology throughout. When you bring out the tape measure and refer to "closest focusing distance" and "focusing distance", you are actually describing **closest working distance" and **working distance**.

Focusing distance is from the subject in focus to the camera's sensor.

Working distance is from the subject in focus to the camera's objective (outermost) lens.

So, if you put (say) 35 mm of extension tubes onto a camera with a 24 mm lens, it won't focus because the subject would need to be inside the lens; that is, the *working distance* is negative.

In that scenario, the focusing distance is still a positive number, but functionally meaningless, because it's now impossible to take a focused image.

I shoot Olympus Micro 4/3rds and a concept was mentioned in one of the streams I follow (fellow Oly shooters) that we can use the extension tubes with the Olympus Teleconverters to be able to use the Teleconverters with MFT lenses other than the 3 pro lenses they are designed for. I even read a thread on DPReview on this topic.

My goal was to increase the reach of my telephoto with the teleconverter and using the extension tubes to get the clearance between the teleconverter and the back element of the lens. I have received conflicting answers on the compatibility between the teleconverter and the extension tubes though.

So I was actually thinking of going that route. However, this video brought some interesting factors into the mix that may be bringing this concept into question.

I was wondering if you had anyone has any insight regarding this concept. Does this sound feasible at all?

Thanks in advance

Great explination

Very nice video. It’s cool to see how close you can get with extension tubes. Thanks 😊

Hi, I'm a bit confused about zoom lenses. If I use a 16mm extension tube on say a 12-60mm lens, will it work OK once it's zoomed in to 16mm or closer, or is a tube of 12mm or lower the only option that would work with the lens full stop regardless of the focal length used? Hope that makes sense, thanks in advance for any insight.

Great video and thank you! Does lens image stabilization work with these extensions? I might get a set for my pan 30mm macro just to allow increase distance between sensor and subject while retaining 1:1. However if no ois then that is a drawback...

good video man !! thanks for teaching how to use the macro tubes!!
best regards from spain!!

hi you are great can i use 12 60

I probably still prefer focussing manually, but holding onto the metadata and having aperture control are the selling points for me.

I was viewing another cool YouTube video describing one man’s macro - or maybe even micro - videography for a client that wanted mould to look like fields or wheat or forests or alien landscapes. I’ll have to view it again.

I recommend buying any of the MK-P-AF3C models (not the cheaper MK-P-AF3A or MK-P-AF3B models) because it is "all metal" construction, and the price difference is ridiculous, like $5 or less.
