Buy the MEIKE, it is most likely exactly the same, and slightly cheaper. I did see the review that mentioned MEIKE, probably before I bought it.
It works, but if you use both tubes, and the Olympus 40-150mm @ 40mm, you have to be really close, less in the frame then using it at 62mm.
That's a budget macro 62mm lens. I probably won't buy the Sigma, it's pointless, the Olympus is fine. Probably is way better outside. The pictures are still uploading.
There's detail that isn't on my YI 42.5mm in macro mode. So the extension tubes were worth $30.
Now waiting for the server, to generate the thumbnails. I did email BuyVM, asking to upgrade to the $15 a month plan. Then I can peg the one core 24/7.
You can see the pictures taken with it here. The boxes obviously weren't taken with the tubes. No medium size image, so to much work to embed it any here. Look at the last two, that's at 40mm, so if you want to be super zoomed in, use a lower focal length. Must have to be closer. How will 12mm work? I have a Panasonic 12-32mm.
There's more detail at 40mm. Less in focus too. Trying to find the right distance blows. Even without the tubes, that lens is picky. Won't focus if to close.
There was no seal on the box. Probably got sold another open box item again. I'm to lazy to send anything back.
Nope, the YI has detail too. Just more bokeh on the Olympus lens + tubes.
Why doesn't Olympus sell official extension tubes? They'd make a fortune, unless they overcharged, which they would. In that case, MEIKE will make a fortune. I don't see the point in a macro lens now. The tubes work just fine.
If you want more in focus, use focus stacking. I'm to lazy to do so. Need to go outside, nothing small other then my dong to take pictures of inside. And that would be very difficult with a 40-150mm zoom lens, it's huge. Good luck zooming in to 62mm, and being far enough away.
Only your first 10,000 photos are bad, and your next 10,000 aren't much better? I have over 20,000 files in my pics folder. That includes the RAW files. That means all my pictures aren't very good. It'll take a long time to get 30,000 pictures, especially if the RAW file doesn't count as a separate image.
