I’m sparingly using Fujinon XF 100-400mm lens for about a year. It’s great tele zoom lens for wildlife shooting, and I never had any issues with it. This zoom delivers sharp detailed shots at whole focus range and is durably designed and built. In this article I’m disassembling front area to remove dust located under the front glass element.
I’ve purchased 7Artisans 35mm F2.0 lens in Sony E mount directly from 7Artisans factory. It arrived quite fast (in 2 weeks) and today I had a chance to extensively use it outdoor. Seattle Volunteer Park has nice selection of flowers for relaxing shooting and experimenting with a new lens.
Fujinon XF 35mm F1.4 R is one of first three prime lens developed for Fujifilm X mount cameras. I personally think that this particular lens is a real Fuji gem among other XF lens. I love the pictures from this glass, and like the mechanics. In this article I’m disassembling my Fuji XF 35mm F1.4 lens sample to expose the process just in case someone is looking for repair steps or needs to lubricate the focus or aperture ring.
Mitakon 35mm F0.95 Speedmaster version II lens has clickless aperture ring with same texture as its focus ring. I’m shooting with this lens since review on March 2016 and it’s one of my favorite glass on Fuji X cameras. But I often mistakenly turn aperture ring instead of focus while looking through camera viewfinder. Manual lens with aperture-clicks are more convenient for shooting. You can blindly change aperture value by counting clicks, and that value remains selected.
In this article I’m showing how to modify Speedmaster 35mm F0.95 II to the click-stop aperture mode.
In this article I’m showing disassembly of the front area of 7artisans 7.5mm F2.8 Fish-Eye lens and sharing thoughts on its build quality. I’ve received this interesting lens sample about month ago from 7artisans, as a redirected customer return ( Thank you 7artisans! ). I was very curious why the lens got returned expecting some issue, and also interested to try another fisheye on Fuji (last one I’ve used before was quite good Samyang 8mm F2.8 UMC Fish-eye Mark II).
Shots are taken from tripod with Panasonic DMC GM1 camera, at ISO200. Lens compared:
- Voigtlander 25mm F0.95 ver I (MFT mount)
- Mitakon Speedmaster 25mm F0.95 (MFT mount)
I’ve tried to focus at same distance, but images from Mitakon 25mm F0.95 have focus center slightly forwarded, so just take that into account. JPEGs are re-compressed for smaller file size, though original resolution is preserved (click to open full size). First image in groups are from Voigtlander 25mm F0.95.

I’m shooting with APS-C Mitakon 35mm F0.95 Speedmaster lens since it release in 2016, and already disassembled it numerous times. Today I’m going to disassemble another Speedmaster lens – Zhongyi Mitakon 25mm F0.95.
It’s smaller model from Zhong Yi Speedmaster series designed for Micro Four Thirds sensor size. And it has exactly same design of focusing area as its larger Speedmaster brothers: 35mm F0.95 (APS-C) and 50mm F0.95 (Full Frame). So you can use this disassembly guide as a reference while maintaining other Speedmasters.
The lens sample is generously provided by Greg Hall (thank you Greg!). I’ll probably also find time to make short comparison of this lens and Voiglander 25mm F0.95 prior to returning the lens sample to its owner.
