High Quality Extension Tube for Sony a7R IV
Posted: Sun May 16, 2021 9:55 am
Can anyone recommend a high quality set of extension tube(s) that will work reliably with a Sigma 105mm f/2.8 DG DN Macro Art lens?
The reason I'm asking is that the Kenko DG extension tubes in many reviews appear to have mounts that fit loosely, particularly when supporting heavier lenses and/or tubes are used in tandem e.g. 10mm tube + 12mm tube. I use to own Canon 25mm + 12mm tubes that I would stack with a Sigma 150mm lens attached with no problems, as there was no play in the mounts of the tubes. But most of the reviews I've read mention that the mounts of all the cheaper tubes have play even the Kenko which garner the best reviews. This setup will be used with a Sony a7R IV so any movement in the tube mounts will show up in long exposures.
