7:45 I think the problem was that there was very little contrast in the focus square so it had a hard time telling weather it focused correctly or not.

Thanks Dave, your videos is always so very helpful

Yeah, its a great camera, Saw your first review and ordered one. But i ordered that Barlow lens straight away and that combo is really nice. Tried some other lenses to but this is probably the best combination...

Hey Dave! Greetings from Ireland!

Thanks. I'm trying to find a good soldering scope that doesn't take up too much space. I like the idea of mounting this on a arm if you can keep it from wiggling.

That was great! What else will you show us before you move?

A Barlow lens is a concave lens used as an auxiliary lens in telescopes to increase focal length. What you have are just auxiliary lenses.

I believe the focus on those cameras work by contrast detection. When the auto-focus started misbehaving you had just a more or less blue area on the focussing area - that's why it wasn't able to focus, I think.

Excellent

I don't need a microscope, but I want one of these. But, alas, no. I'll stick with wearing two pair of reading glasses (which works amazingly well).

I did not think I needed one but I am the same with good recommendations and recovering from past purchases. I got one and have tons of uses for it now. I'm also getting some Barlow's and going to use it with an old telescope. Weather permitting I'm in the UK. it works brill for spotting marks on so called new items. Call out the seller and normally get a refund of some kind or a Free return when the items not worth it. :-) One of my best buys and the grand kids also love it they now come armed with items they wish to see with Grandads Super Zoom power and they also bring a usb so they can get a copy of the pics. Worth it weight in gold just to see them so engaged and who knows Dave may well be responsible for the next Astronauts AKA Tim Peaks, Physicist Bryan Cox, or Engineer James Dyson. :-)

Dave, I'm guessing you have worked with both types of microscope - trinocular and just the camera like in this one. Do you find one better than the other?

I am using a ezcap287p HDMI to USB3 capture unit, that works just fine with the eakins, and my splitter (which looks physically the same as, but has different silkscreen to yours), also my splitter is being powered from the USB3 port without external power.

I should find out which HDMI splitters we use at work to feed the foxtel set-top boxes into our RF system. I believe it's a jaycar cheapie, but it gets rid of the copy protection or whatever pretty well.

Bought one of these since Dave's first Eakins video. Been a happy camper, except I'm not sure if my autofocus works as well as Dave's: it's jumping around quite a bit sometimes, and focus range doesn't seem to be as good. Maybe it's because Dave has better lighting. I have the 120x and 180x objectives; now ordered the Barlow lenses ;)

Very nice scope but recently prices shot up- only a couple of years ago these were 50% of the price- the barlow lenses though are quite cheap because for binocular microscopes they cost more and they aren’t much different. Magnification being the thing many manufacturers charge almost a third more for something that provides a total of x90 vs one with x45. Like everything its a jungle out there and they have to compete on the price of the standard kit and make their profit on the accessories. Keep up the good work and the great variety of posts. Im learning a lot (a pom learning from an antipodean? Whatever next eh?) with 11/11 looming let’s remember the fantastic contribution of the Anzacs to the WW’s. Thanks friends!

How many of those Barlow lenses could you glue together and still have it auto-focus?

Please open up the camera and show us the mechanical autofocus. How many camera are there that move the sensor relative to the lens? Thanks

I got the 0.35, 0.5 and 2.0 lenses I found using the 0.35 worked best for my situation, I have also ordered some extension tubes to allow me to raise the microscope up higher to be able to use zoom above 3, auto focus has been really good to have ! I am using the 120x assembly not the 180x. I have some footage recorded for a review video, but haven't got around to it yet. I have been using it to do liquid damaged Macbook Pro repairs, doing 0402 and can use a 10" screen just fine.

Same as others say, don't need one, want one.

I'm able to get great results using a DSLR camera, extension tubes and a normal lens from my old camera. I built a jig to photograph 35mm slides, and can pick up grain on Kodachrome 64.

I don't need to use a microscope very often, so I also use my dslr with a 70-200mm lens, a close up lens and 2x and 1.4x teleconverters (barlow lenses). That works amazingly well with a great zoom range, autofocus, more than 300mm working distance, and at maximum magnification I get an amazing 12mm wide field of view at full hd resolution. Can get even closer than that if I use 1:1 sensor resolution.

When you find the lens you ordered months ago cleaning the lab...ahaha

Hello, what is your lens model from eakins? And what is your maximum magnification you can reach with it?

What part exactly is responsible for the auto focus?

Did you update the cable spec for hdmi 2.0 to support 4k? The cables are often a problem as they don't all support the higher bandwidth. Apparently hdmi 2.1 supports 8k. But using an old cable won't give the full experience.

Lattice IC is a CPLD

Kicks the ass out of the magnifying lens on my third hand tool by a couple orders of magnitude. Price is also a couple orders of magnitude greater. I suppose the USB scopes that run about 50 Yankee bucks would be midway between the two on a log scale.

What lens should be used so that it can be placed at a distance of 60 cm from the desk top and, at maximum zoom, obtain an area approximately 2 cm wide?

its a focal reducer not a Barlow lens , Barlow increases magnification

Dave - your wife called: "Have you finished packing yet?" :)

Would you reccomend , the Barlow lenses for Extreme Macro Photography....??? I need the closest vision and details.. Do you think it´s gonna work well ... ?? . Thanks.

Great but.......You better keep focussing on the job at hand. Sorting and packing. I've been there.

Nice. I have a similar setup but without the auto focus. Of course none of my barlow lenses from previous microscopes are the correct size for it. I should order one with the correct thread. I generally prefer my Andonstar models (not quite sure why...) but this model with auto focus would certainly be a welcome upgrade, plus that tall stand!

You can, just the lenses would be massive. Since 2.4GHz has about 12cm wavelength, a refraction lens would have to be hundreds of meters across to provide any kind of focusing power.

Too blind now to solder. What else about it? It can connect to 720 and 600 monitors too. Also the 51mp is just about 6x times 1080p.. So you wont be taking 51mp picrs but what it does is give you up to a 5 or 6x digiral zoom. Kind of useful. I cant get usb to computer to work for me.

Flemming Jacobsen basically it’s a mild reducer or magnifier which when used in conjunction with its black tube may unflip the final image by 180° in circumstances when it’s impossible to flip a real object, of course with minimal loss of luminosity. In this case its only practical application is like putting a fixed-focus lens on an autofocus camera to shift its entire zoom power range around, which for a ‘reducing’ Barlow (fractional power) adds the benefit of increasing field of view, such that very little of its original autofocus capability will be lost even while increasing the distance from the object to the scope. Any added extremity or ordinary (non-Barlow) complexity often dramatically decreases depth of field and obviates setting any ‘back focus’ especially when the lens diameters are small, and large high-powered ‘objective’-lenses with short focal lengths are so expensive that when possible they are omitted in lieu of low powers in conjunction with an extra-long optical tube or if there is a cheap but standard lens that’s slightly overpower, a fractional Barlow added to compensate.
