Was that a close enough look for you? See something on the show that you want to buy? Head on over to kit.com/PhotoJoseph MEIKE MK-P-AF3A Automatic Extension Tube amzn.to/2GB5X4N
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!
Just like any lens, the smaller the Aperture (which means the bigger the number, because an aperture is a fraction; eg f/22) the larger the depth of field. But in macro work, even a large depth of field can be extremely small. Search for “macro focus stacking” to learn ways around this!
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 RU-vid 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.
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...
Great question. If it’s an active tube, meaning it still has Aperture and AF control, then it should. If it’s passive then it definitely will not. But also remember that some cameras have IBIS in the body too, so that will always work.
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
I’m not familiar with those teleconverters, but I would certainly question the validity of this idea. An extension tube is changing the distance between the lens and the sensor, which as you saw here changes a lot of things about how the lens works. The good news is you can order these things on Amazon for cheap and return them if they don’t work.
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.
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.
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.
