Inon UWL-100 vs UN PWC-01 wide angle

[ReyeR]

Stackable means that you can screw one close-up lens on top of another, potentially giving you more magnification. This is only possible if the close-up lens has threads on the front of the lens (like the threads on the housing port). So you screw one close-up lens on the housing port and the second close-up lens onto the front thread of the first close-up lens.

The Inon UCL-165 is stackable for the above reason. The UN PCU-01 is not because it doesn't have front threads.

In the picture below you can see the UN lens stacked on top of the Inon lens.

I use a S&S WA 'L' lens. No distortion, no blurry edges. With the 5050 I do have to bump the zoom in a bit to eliminate a faint vignet shadow in the upper left corner but that's no biggie.

no barrel distortion?

what problems do the Inon WAL have?

I didn't say the Inon WAL had any documented distortion problems.

When I was shopping for a WAL for my C-4040 a couple years ago, just before the Inon's were released, I noticed blurring and vignetting on alot of the photos I was seeing posted on the 'net. Most of those were taken with the Oly WA lens.* Since I had been using a S&S WA lens on my old MMII rig, I was familiar with and pleased with the quality and performance of the lens and decided to continue to use the S&S brand lens. On the C-4040/PT-10 rig, the S&S lens showed no blurring around the edges or vignetting. On the C-5050/PT-15 I now have, I get a faint vigner shadow in the upper left corner but a quick bump of the zoom lever eliminates it.

*Before someone jumps on me here, it was just an unscientific observation on what I was seeing. Alot of people are perfectly pleased with their Oly lenses. To each thier own, YMMV.
