EAKINS VS RF4 trinocular microscope comparison

hello Internet this is going to be a bit of an unusual video for all of my repair Tech uh friends out there that are looking to maybe upgrade their eons to uh rf4 and uh so um right out of the box it feels very very light so my guess is uh not only that not only that the Optics are plastic probably and uh this this thing here is also plastic this here is metal so the weight is dramatically different and so um everything else is the same so the sizes of this and this and all your lenses and everything including the eye pie will are completely interchangeable so they will fit into here they will fit into the other one um now the biggest issue and the reason why I'm making this video is to give you a warning morning not to this thing so and I just bought the head thinking okay I'll you know I don't need the whole thing since it's going to fit probably going to give me a better better zoom in and out action as they advertise in their videos all the time on AliExpress uh so that didn't work either uh though it was a little bit better than eans uh it was a bit more in Focus but still if you scroll all the way on in in and out you're still going to be losing focus either on one end or the other though a lot better on this uh than on that and that probably has to do with the way that the Optics are actually adjusted so that once you zoom in the focus isn't Lo Focus isn't lost bottom line is uh it's only better for zooming uh and uh but but the whole purpose of the trinocular microscope is that you're looking through it and that brings me to the number one reason not to buy this piece of trash is because you cannot use it it as a trinocular scope the reason why that is is because if you were to at the way that the lenses are positioned
