Brightin Star 35mm f9.95 M43 manual focus lens

Image
I have been an Olympus/OM System micro four thirds user for many years. I love the format, cameras and lenses for many reasons, including the small size, light weight and quick automatic focus. But I also enjoy photographing some subjects with third-party, manual-focus primes on my Olympus E-M5 and E-M1, taking me back to the days of shooting film with less-sophisticated cameras. But the manual-focus primes are best for portraits and still-life shots, not for anything involving action. My first venture into the manual-focus lens world was an adapted used and cheap lens from an old Olympus film camera. Not satisfied with the speed, I stepped up to a new and expensive Voigtlander Nokton f0.95 17.5mm lens.  The robust lens produced images with a unique character, which I loved. The well-built he lens was big and heavy, which I did not like. It was like a having military tank mounted on the front of the camera.  Here's a shot from the lens, stylized to give it a black and white fi...

Another OM-System Lens

Image
The Olympus (now OM Digital Solutions) announcement last year of its new M.Zuiko 100-400mm f/5.0-6.3 IS lens immediately grabbed my attention.  As an enthusiast micro four thirds amateur, I have a variety of prime and zoom lenses but none to cover the longest telephone range.  My lens lineup includes an Olympus M.Zuiko Digital ED 75-300mm F4.8-6.7 II, but I have found it just a bit short on some occasions. In additional to the 400mm reach of the new lens, it can focus very close throughout its zoom range, making it valuable for shooting macro/closeup images of flowers and insects at a distance. Another benefit is compatibility with the standard Olympus MFT teleconverters, the 1.4x MC-14 and the 2x MC-20. However, the large size and its hefty price tag of $1,500 USD have made me rethink the the value this lens would be for me. I used to do a lot of photography on mountain hikes but never pursued birds or wildlife. But as I have gotten older my hikes have become less strenuous w...

Closer Look at the OM-System 50mm Macro

Image
 Here's a black and white image of the legacy Olympus OM-System 50mm f2 Auto-Macro on a modern micro four thirds camera -- the Olympus OM-D E-M1 Mark III. Because this prime lens was designed for SLR cameras, it's big and heavy, although the Olympus OM-System was smaller than other SLRs. The grip and the size of the E-M1 III make it work well on this camera. I would not want to use it on my smaller PEN-F without a grip attached. This copy of the lens, which I acquired used on eBay, is in good shape, and looks great on the camera. The wide rubberized focus ring operates smoothly with its wide throw. For manual focus work, I prefer this approach to the focus-range switches used on later model macro and telephoto lenses. The aperture ring with click stops is located at the front of the lens. A focus-distance scale is found at the back of the lens behind the focus ring. A Fotodiox Pro OM-MFT adapter attaches the lens to the micro four thirds camera. This lens and virtually all of t...
