JJC Micro 4/3 Auto Focus Macro Extension Tube for Olympus Panasonic Camera

- Full autofocus, electronic manual focus, exposure, and aperture control. - Easy to install; mounts to body just like any other lens, and lenses can be mounted as if it were a body. To remove lenses, just need to pull back tab in the adapters. The adapters connect to each other just like lens and body. - Feels sturdy, both adapters appear to be strong plastic with metal face - Uploaded examples using 25mm lens with the 10mm adapter, and then using both 10+16mm adapters

Set of two (10mm and 16mm) JJC extension rings arrived yesterday. Metal construction; solid lockup, no wiggle. No problem with focus and aperture etc. signals between camera and lens. Bought them to play on my Pana GX85 with the kit lenses; first camera with interchangeable lenses. Looked at several sets on Amazon, picked this JJC set as having decent reviews and being a bit above average in price range. (Yes, you can pay too much and get trash, but rarely get satisfactory quality without paying for it.) The 16mm is too much extension for the 12-32mm lens. The 10 and 16mm rings, singly or in tandem, work well on the 45-150mm lens. Have done some macro pics with single lens cameras, but camera is so close and blocks even lighting. Extension ring on the long lens gives a very tight angle of view from several feet back. No camera shadow.

Results are subpar, lots of blur on the edges. If you want to take decent macro photos just buy a good lens or even a cheap lens will do better than these.

it is every thing i expected no more and no less

Bought these as cheap macro adapters, they work as advertised. Tested them with both M.Zuiko 14-150mm f4-5.6 zoom, and with a 7artisans 25mm f1.8 prime lens. Autofocus on OM-5 was a little unstable with the zoom at full power; manual focus works quicker imo.

This is a very good product at the right price!

Works great on my OM-1. Couldn't find out a lot about these so I just picked them up on a whim. My 12-40 f/2.8 lens is practically useless with both tubes attached as it places the focus plane practically inside the front element of the lens. Conversely, my 40-150 f/2.8 works fantastic. Around 70mm I can place the front of the lens a good six inches away from the subject. Basically, the zoom works as the rough focus, and the focus works for very fine focus. Definitely cheaper than a 90mm macro lens, but the usability is nowhere near a dedicated macro lens. Worth the $40, easily, especially if you aren't doing serious macro work and just wanna mess around. Attached is a roughly 40% crop of a photo taken around 70mm @ f/2.8 of the mesh on top of my microphone, SOOC large jpeg set to fine+neutral.

Could use better explanations in Manual, including technical explanations, and lens compatibility.

Used the 10x filter on a G85 with 12-60 kit lens. Auto focusing worked well and the clarity was very good. Good value for your money.

Good quality extenders, allowing for greater closeups of macro shots.

These work just fine on my Olympus E-M10 mark ii. They attach and release smoothly to both the camera and my lenses. The worked fine with my 3 lenses and autofocus works. They came with a body cap and a rear lens cap to cover them when storing in your bag. They are mostly plastic and they are pretty light weight, so I don't know if I would want to put a big, heavy pro lens on it, but they are fine with lighter weight lenses like I have (the two kit lenses and the Panasonic 25mm f1.7). For the price they do the job just fine.

They function as advertised. Great for closeup work. Highly recommended great value

works exactly as my son the photographer wanted them to.
