Steve,

A couple of reticules are sent with the SF-100 and they are user changeable in the appropriate eyepiece.
The scale is etched on one side of the disc. Remove the reticule from the eyepiece and turn it over as the etching may not be at the focal plane of the eyepiece. A reticule must be calibrated at each magnification using a stage micrometer. An explanation for calibrating a reticule with stage micrometer are on the microscope blog on our microscopes website Microscopes.com

Robin,

Received the scope, and I will post my "review" shortly. But first, I have this question:

Is there some kind of trick to using the eyepiece with the measurement scale?

My problem is that the scale is almost invisible, so measuring objects is very, very tough.

Any thoughts will be appreciated.

Thanks.
Steve.

Hello 10X,

To answer your questions:

1. Zoom is a personal preference. If you wish to know your exact magnification then zoom is not for you. I believe quality of the optics is more important than zoom capabilities and the Lomo has great optics.

2. The light source on the Lomo SF-100 is an incandescent bulb, not good enough for photography but just fine for viewing. The beauty of a stereo microscope is that you can add your own illumination. For photography the ringlight in the SF-100BF or TF is the best option. If the ringlight isn't in your budget now it can always be added later.

3. Lomo has the best optics by far than any other stereo microscope we carry, excepting Nikon and Zeiss.

4. The best way to take photos is with the photomicrogaphy attachment which comes with the SF-100T or TF; this places the camera at the exact focal point of the microscope image. The phomicrography adapter is a T-Mount adapter designed for SLR cameras. Whenever you use a camera with a microscope you loose the eyepiece magnification and replace it with electronic magnification from the camera so the quality of the camera is important.

I hope this answers your question. Feel free to contact us at 800-504-5897 option 4. or email to labsales@opticsplanet.com

Hi

I am new to microscopes, though I am an experienced photographer. My budget is up to $600 for the scope.

In a nutshell, my interest is to view and photograph (micro)fossils in the range of .5mm to 25mm, using my Canon DSLR.

I have read nearly all postings on the microscope forum here, and have been impressed with the apparently unbiased and professional responses.

My eye is on the Lomo SF-100 w/trinocular but I want to ensure it is the best fit.

Questions:

1. Zoom vs non-Zoom microscope: A friend on a forum told me that having a zoom on the stereoscope is essential. Of course, the SF-100 does not, though it has the 5 magnification steps available. Is the zoom feature considered by most users to be a high priority feature? What about your experience? Does the 5 positions on the Lomo mitigate the non-zoom disadvantage effectively? If not the Lomo, then what scope would be the best fit?

2. Light source: I notice that the stock SF-100 is noted as "incandescent". Can you please explain if most photographers will be satisfied with the stock illumination color balance on the Lomo? I know the ring light is available, but it is a pretty significant bump in price, but worth it?

3. Brands: Can you briefly state how Lomo, Konus, and VWR compare to each other? Do many non-pro users recognize that the Lomo brand (European) is of higher quality than Konus or VWR that are made in China?

4. Taking photos: Can you briefly discuss the pros/cons of the different ways use a camera with a scope? Please address a)just pointing the camera at the occular, b)mounting the camera to the eye piece, c)using the trinocular.

My main goal is to determine if the Lomo is the best fit of quality and features for my intended use and budget.

I know this is a lot, but myself, and likely others, will appreciate your insight.

Best Regards
Steve.
