This is a quick follow up on my previous video where I reviews the Lapsun 4K microscope.
In the video I am testing a 0.75x Barlow Lens I have purchased. Will it work and be useful?

After watching your videos on this Lapsun after trying and returning an Andonstar AD249S-M microscope that was more like a plastic toy, I bought a Lapsun entire setup with 180mm + 0.5x converter. This gives 17cm working distance. I too was blown away with the quality for the price and am very happy with my purchase. I paid £315 inclusing a base, shipped to the UK and an Andonstar AD249S-M was £260. Thank you so much for doing both the videos, they helped me immensely.
Thank you so much for your nice words! I also reviewed the AD249S-M (or is sub-brand) and I am glad you agree with my conclusion! I think I also called it "a toy" at some point (clearly the last item they'll send me to review but hey...) kzhead.info/sun/itNylb6mnJhvhKs/bejne.html I'm happy to hear about the Lapsun. I should have gone for 180x + 0.5x as well, it's probably the sweet spot. But I am happy with my unit though, no regrets. Thanks for watching!
I glad your experience was positive with Lapsun. Many customers have been on the opposite end though so be careful and do your research if you decide to buy any of their microscope cameras etc. What microscope camera model & set did you buy? I purchased one MS camera from them about 2 years ago and I was pretty unhappy when it arrived. Around this time is when they completely stopped production on the IMX290 MS cameras and Lapsun did not tell me or about 20 other people who purchased one. I received the IMX307 MS camera version and right away you could tell it was much worse. The video quality and framerate was below my likings. The IMX307 MS camera and many other they sell use a " interpolation method to produce a "60 FPS" frame rate. It was more around 30 FPS or 45 FPS with stutters / slight choppiness / lag . They originally did not want to refund me but Ali-Express forced their hand. What was crazy though is the seller working there really tried to tell me they were selling genuine IMX290 cameras still and sent me PCB picture of the motherboard stamped **290** which refers to the sensor that's soldered on the board. The picture was an old picture from when they really did have them. I already had 1) IMX290 camera from Eakins from the prior year so I knew something was off and decided to take it apart. When I opened it up the MB stated *** 307 *** and right away I knew which sensor it was. I really wanted to try out another camera from them but I've decided against it because who really knows what sensor they are trying to sneak by customers who wont investigate if they think something it up. Eakins is much more open and honest about the cameras they sell now and RISING CAM a RT5109 - 4K true 60FPS HDMI preview camera ( no interpolation that I can tell ) that has some of the best video quality I've seen. The IMX290 models were amazing and I wish they would bring them back but now the only few sensors I think work best are going to be the : IMX334 ( from RISING CAM ) , IMX385 ( V2)
Hi, would you be able to provide a link where you bought yours, im also in the uk and im really tired of these low quality digital microscopes
@@shiftctrlhack Sorry for missing this reply. I did mention some concerns about Lapsun's customer service in my main video. I believe I did say I would think carefully when buying more expensive ones. As a minimum, it must be covered by something like PayPal so you can return it if it does not match the description. In the end, not even mine matched the description - but I was happy with the quality so I did not complain. Thanks for mentioning though, it's a very good feedback. (I;m not affiliated with them BTW! :) )
@@nutterhm Sorry for missing your reply - Lapsun are on Ebay (Lapsun_gift) and if you get in touch they can sell you directly - but please make sure your purchase is fully protected by something like Paypal (check the T&C to see what's covered or not) as even my scope was advertised with a sensor and it arrived with another :)
Well, that improves things nicely! Looking forward to you putting it to work.
Hello Tony, thanks so much for both your videos about this camera. You covered a heap of important details, extremely helpful, greatly appreciate your work.
You're very welcome!
great backing track.
Thanks!
great microscope
Beautiful, very very good!!!! 😉 🔝
Thank you very much!
I dont want to spend that much, but i like the 180 lens with a 0.5 barlow, and the stand. What budget camera should I get?
Yes I feel 180x + 0.5Barlow would be the best combination. I'm afraid I don't have experience with anything else but I'd stay away from those with the integrated screen. They might be a little cheaper but something like this Lapsun is vastly superiore in terms of ease of use and performance. Check the "Joylens" review on this channel! Thanks for watching!
Hi. Nice review. Do you have a link for the barlow lens (x 0.75) or any specification?
Hi, thanks. I guess it depends on the lens where you need to fit it to. A 0.75x barlow should be a 0.75x barlow. Whether the C-mount lenses are all the same, I do not know. Your best bet would be to contact the manufacturer of your lens. Thanks for watching!

Hi I’m thinking of get the same microscope or the lapsun 4K 48MP 1080P 60FPS HDMI are you still happy with your one pal or do you think the other one I’m looking at would be better. Kind regards Andy
Do you have a link for the other one? I am very happy with this one, particularly with the way I clamped it on my desk. I saved money and it's so practical to use!
I’m gonna do the same sort of thing as I don’t need the platform it comes with. Only thing I don’t like about the other one in the link is the connection are on top.
Did you get the link as I don’t think it’s letting me send it?
@@andreasachilleos6335 no unfortunately, KZhead won't allow that apparently. I might have found it, what I don't like is that the sensor is "anonymous", it says "48.0MP 1/2.3 Inch big size Japan CMOS" :) One of the reasons I went for the one I purchased was that it featured a Sony sensor (which ended up NOT being the one advertised though). To be honest, I feel it's impossible to know what you're getting. Why not emailing Lapsun and ask for some advice? I did that when I got lost with all the models they have and the one in the video is the one they recommended TBH! See if they have some actual footage you could see. Also, I would make sure it works with OBS (if you need that) and also that it works on both HDMI and USB at the same time. Mine does that even though it was not supposed to... And yes, connections at the top are not very practical, I agree. Let me know!
@@tony359 thanks pal really appreciate all your help think I’m just gonna go with the one you have, as that’s what I thought could be any sensor in the other one and is it really 48mp not that I need it for taking pictures anyway. Love you videos by the way keep up the great work. Kind regards Andy
Rather than use a custom washer on the stand pipe, I found it more convenient to cut a piece of PVC pipe (1.5"?) to the proper length and simply slide it over the tube, letting the microscope assembly rest atop it. Punt the existing clamp.
of course that is also a good solution!
I have this camera but the seller i got it from does not sell or include barlow lenses. and i dont know what the thread size is for the barlow lens. does anyone know the thread size or have a link to purchase barlow lenses for this camera?
If it's a C-mount lens, I'd say they should be all the same. Mine has a thread of 42mm - I believe the body is 50mm.
@@tony359 Thanks. the ones i found were all 42mm but i wasnt sure. now this verifies everything. Im ordering a 0.5 and 0.75. one thing i noticed in your video was you were saying you would leave the barlow lens on there as a sacrificial lens to protect the camera. My camera came with a plastic cap that i can slide on or off even if i have the led light attached to it. did your camera come with that cap? if you have it you can use that instead.
I mean a protection from fumes and dirt, not for when it's not being used. I did eventually get a protection but I never use it, the Barlow is enough IMHO!
0.5x is the sweet spot.
So, is there a backfocus in that lens?
Not sure what that is, can you elaborate a bit more?
@@tony359, www.google.fi/search?q=back+focus&ie=UTF-8&oe=UTF-8&hl=fi-fi&client=safari
In short words: back focus: to adjust the lens so that focus stays the same in all zoom positions. In tv work, you do that every day.
I don't think so. I did try playing with whatever I could but never found an adjustment. That said, the focus drift is minimal. It takes 1/4 of a turn of the focus knob to re-adjust it.
@@tony359, you did mention some unknown adjustment on top part of the lens. Have you figured out what that is? Backfocus can adjust also the focus distance a lot.
So you still love this microscope i just looking to buy one, should i buy it?
I still love it! :) Particularly the stand quality and particularly after reviewing a more popular one here ( kzhead.info/sun/itNylb6mnJhvhKs/bejne.html). Just be aware of the sensor "lottery", be clear with Lapsun on your expectations. Thanks for watching!
@@tony359 wow thank for your fast response, i’ll say on order that i want imx 334 right? What do you think about 1080P 60FPS SONY IMX385 V2 does it better than your microscope?
@@MrOmer123 I am really not an expert on other sensors to be honest. My unit says 334 on the PCB as you found. There's another user who commented here who was very very happy with its purchase. All I am saying is be aware of this potential "lottery" and make sure you are using a payment/platform which allows you to return the item if you're not happy with it. Let us know how that goes :)
@@MrOmer123 What did you got now? As I understood the IMX385 seems to have 4x better low light sensitivity (what ever that means) but a smaller sensor. The IMX334 cams seems to be cheaper though but also integraded in more expensive cams. I think I would only go 4k if I could afford a cam with IMX485 sensor. IMX385 cams seems to be the better 1080p cams vs the IMX334 4k cams not really the better ones I think?
Very rarely you would get an update from them or any sellers in China. Once you bought the item and after receiving your dosh they will just wash their hands and you do not exist until your next purchase. This is my experience.
I'm afraid you're right. Thanks for watching
180x lens will bring your scope down and the 0.3x barlow will be handy then. This is what i conclude by watching many microscope videos.
I agree. Those lens are not expensive so I might change mine one day. But I’m pretty happy with it for now. Thanks for watching!
After watching this video I went with the 180 lens and 0.5x converter and this gives me 17cm working distance. Very happy,.
How did you bought the channel to say that its yours?
I'm not sure I understand the question
@@tony359 i was interested in obtaining a channel and asking how did you bought one. I thought ive seen a mention in KZhead user agreement that there is no personal channels there, but i can be wrong. You are saying "my channel" at the beginning so i thought you purchased one
@@za_ozero they’re free! I opened this one ages ago but I think as long as you sign up on KZhead to watch videos, you automatically have your own channel.
@@za_ozero Here is your channel! You have it already! :) kzhead.info/tools/dPsGyec5J-tQzXuEw9oMCQ.html
These types of lenses that are sold with cameras are not very good compared to the professional ones, both in terms of magnification and in the need for extra lenses. Just as they are sold for all types of cameras regardless of the number of mega pixels, which makes them worse. The lenses have a specific number of mega pixels to work perfectly.

I have these two models, they are relatively easy to find on ebay at good prices, removed from end-of-life industrial equipment. The image quality is surreal and doesn't even need lighting if used with the right camera for it, as with the new IMX385 sensors, which despite the low resolution work in near darkness and at 60fps.
Thanks for watching! These are definitely cheap microscopes - there’s no doubt about that! But for the price I feel they’re doing well. Thanks for the hint about the lens. Would you be able to send a link of one of those lenses for reference?
@@tony359 KZhead doesn't let you share links other than KZhead itself. But I found a store in the UK with the computar lens at a very good price, it's called: online security products
