Review, Tested: Kelda 8mm f/3.5 Fisheye Lens for Nikon Posted on March 12, 2015 by lui_gough Fisheye lenses are pretty special when it comes to lenses. Their extreme distortion effect serves to be a novelty, which is sometimes overused , and can prove to be a handy feature to squeeze in extreme fields of view, or to ease 360-degree panorama photo-taking. The number of fisheye options for DSLRs have generally be limited, and it was hard for many to justify spending real money on a real fisheye lens. In terms of options, the one I like most is the Samyang 8mm f/3.5 fisheye (~AU$380), available under a range of different rebadge names such as Bower, Pro-Optic, Rokinon, Opteka, Vivitar, Falcon, Polar, Walimex and Bell and Howwell.

Mine microscope is similar to this one but I bought it from Aliexpress sent via Singapore Registered Mail and arrived in less than 30 days. It came with 5 sample slides which I photographed above. It cost me RM200. No eyepiece. Objectives used were 4x, 10x and 40x. The 40x objective is barely useable. Without the micrometer stage, it is difficult to locae the sample to be photographed. The lack of condensor also reduced its resolution. I was not able to use the microscope because I do not have a suitable lighting. When I realised the LED flash for mobile phone is ideal, I started taking these photos.
