Review on 🔬 Vision Scientific VS-5FZ-IFR07 Simul-Focal Trinocular Zoom Stereo Microscope: 10x WF Eyepiece, 0.7X-4.5X Zoom, 3.5X—90x Magnification, 0.5X & 2X Auxiliary Lens, Double Arm Boom Stand, 144-LED Ring Light by Kanwar Mix

Mine is direct from Vision Scientific, but it's the same dual-boom trinocular scope as here, minus the four-zone LED ring illumination. I'm writing this review because the lack of feedback on Revain initially made me wonder if Amscope would be a better provider. Yes, this is a decent hobby desk oscilloscope, especially for the price. This simulfocal sight was needed to refine the SMD, as the loupes no longer provided sufficient magnification as details became smaller. I chose Simul Focus because I figured I would end up taking pictures with it because I didn't want to sacrifice stereo vision during picture taking and it would be expensive to switch to Simul Focus later. This sight is similar to Amscope's Simul-Focal. Bullet. In fact, I can't find any indication that this is another OEM. Ultimately, you are covered by Vision Scientific's warranty and service, not Amscope's. As a compromise, I got the best price for an equivalent volume. Vision Scientific appears to be primarily a provider to the education market. The scope optics are surprisingly good at minimizing edge-to-edge chromatic aberration. It's not a Zeiss, but it fits my SMD customization needs quite well. The eyepiece shaft is long enough to wear glasses when using 10X eyepieces. I am using this with an AmScope SM07 0.7X Barlow lens purchased from Revain https://www.amazon.com/gp/product/B007LBGVGS to get a good balance of performance and working distance. Alternatively, I could have used the included .5 Barlow, but the .7 placed the scope at a more comfortable (lower) eyepiece height on my desk. How well the area works. Holy cow, I wish I had a scope soon! Finally I can see the SMD connectors properly for assembly and inspection. Now I can be sure I'll see what I need to see. There were a few things to do upon arrival. The molded foam packaging was intact and the parts arrived undamaged in transit. There were two scratches on the top of the base plate, but they wouldn't bother using it. This is a work tool, not a display item. The upper boom shaft linear bearings were installed and shipped without lubrication. So I disassembled the boom and stuffed the bearings with lithium grease. The lower boom shaft plastic bushing was filled with lots of metal shavings that I had to clean out. A few metal filings were also found in the eyepiece mounting tubes. Nothing serious, but the visor should be inspected and cleaned before use. The two anti-rotation screws/knobs terminate in sharp, bare metal ends that can dig into the shaft surface. This was done by placing a piece of nylon in front of the ends of these bolts. After a little cleaning, lubrication, and anti-wear protection, the scope was ready for assembly. Buyers should expect a little work before final assembly. Otherwise you will see premature wear. Application Tip: Support the weight of the scope body each time the boom is retracted or extended to reduce wear on the boom shafts. Overall, I'm happy with this addition to my desktop. So much so that I ordered a camera and C-mount adapter from Revain.
