DIN objective for Meiji ML5000 question

I have a Meiji ML 5000 microscope that according to the manual uses DIN objectives. I am looking to get a 5x objective to use mostly for darkfield pond water work. When I look at objectives on ebay they seldom say if the objective is DIN or not. Can I assume that most modern objectives from Japanese...

Cleaning camera adapter glass to perfection?

I have a camera adapter that I cannot get perfectly clean. I tried hand blowing dust which still leaves some (few) particles. Then I used Pock optics cleaning solution with a PecPad wipe which left a little residue and a few particles. It is not bad by any means but I would like it to be perfectly c...

Dear Tom,

Thanks for relating your 4K video experience. It is very helpful.

It sounds like 4K is just about there but not quite there in terms of home processing as yet. I guess I will watch it all develop in the meantime.

Good micro-observing to you.

4k videomicroscopy?

Is anyone here using a 4k camera for videomicroscopy here? Do you have any links to specimen 4k micro-movies? I am thinking of upgrading my eleven year old Canon S3IS to a Canon full frame 6D but will I be investing in technology that will soon be a thing of the past? Is 4K the future for videomicro...

Pau,

Yes, that is my microscope since 2005. I used it for many years with a Martin camera adapter and a Canon S3Is for video. But now I would like to use live view on a computer screen. Time to upgrade my camera.

Hi Pau,

Thank you for your reply.

I have a Meiji 5100 trinocular microscope and am considering a Martin Microscope camera adapter which will accommodate a full frame camera.

Canon 6D for video microscopy?

I am thinking about getting a refurbished Canon 6D mostly for video microscopy of microbes. Is this camera a good choice for video microscopy?

Anything better?

Thanks for your reply in advance.

Microvideography camera question

I am thinking about getting back into video-micrography. My old 2005 setup used a Canon S3 IS on a Meiji ML5000 microscope and I am trying to get up to speed with the technological advancements in the past ten years. I have a Canon T1i that I could dedicate to the microscope. But I am wondering, spe...

Two rotifers for identification please

Update: I might have made a mistake by posting a poor image so have removed it in hopes that they can be identified from the video which is much clearer. I am hoping to get identifications for these two rotifers. I posted a video here that shows them interacting : http://vimeo.com/92404122 I think t...

Near-infrared microphotography ?

Greetings. I haven't posted here much in the past few years as I have been mostly imaging bigger phenomena ( transient luminous events) in the mesosphere. In the meantime I have acquired a modified full spectrum Canon T3i DSLR camera in which the infrared blocking filter has been removed and replace...

Nikon Small World in Motion - 2012 winners?

Hi. I am wondering what happened with the 2012 Nikon Small World in Motion video competition?

It appears they posted still image winners for 2012 but not video winners?

Thanks in advance for any information.

Hi NU,

Yes, maybe it was a Swallow Bug. Hard to tell from a crunched specimen. The rural ranch had swallows, bats, and the people also traveled to cities so it might have been any one of the Bed Bug type species.

Bed Bug or possibly a Bat Bug?

In the year 2006 my neighbors here in rural New Mexico asked me to identify a bug that they assumed was a Bed Bug. They gave me a dead one in bad shape, and I took some photos of it with my old Spencer Buffalo microscope. I researched a little on the internet and at the time I thought it might actua...
