Most Helpful Positive Review Quality & Preformance
Meets all of my personal needs. Great instrument for repairing Aircraft bubble sextants & navigation equipment as well other delicate instruments in the fields of weapons and guidance systems. Excellent for comparing projectile rifling and other deformations. All around excellent piece of gear!!
Most Helpful Negative Review New Old Stock?
You certainly can't get more for you money, but this scope is obviously very old with corrosion inside, oxidized rubber parts and mold on the lenses. After a rebuild, works well, but is not in "new" condition. Pros: Great optics for the money Cons: Appears to be very old with corrosion and mold on l...

No more arm?

by Legacy Reviewer, Written on April 11, 2012
I have three of these and have in the past had no hesitation recommending this fine instrument. As they will no longer offer the arm option, I will not be able to recommend this anymore.
Pros: Inexpensive, Good quality, excellent value
Cons: No more arm mount. (ever?)
Would recommend: No

LOMO SF-50 Stereo Microscope, Trinocular

by Legacy Reviewer, Verified Owner from GA, United States Written on February 1, 2012
hard not to recommend given the price. But it is old Russian stock. First one I received had a lens alignment issue at the highest magnification. OP are sending another (haven't received it yet.

The optics however are great, and it's hard to beat for value with all the extras (graticules and triocular module).
Pros: Great optics and accessories for the price
Cons: Old Russian stock - you take a chance that it's all in working order
Would recommend: Yes

the lomo stereo-scope for technical work.

by Legacy Reviewer, Verified Owner Written on June 29, 2011
This is a great stereo-microscope. The Optics is first class. The 170mm standoff distance is a must for electronic rework with a soldering iron.
The standard illumination system is from another era but once replaced by a powerfull LED source, this Russian creation really shines.
Pros: great 36x at 170mm distance, sf arm is very stable
Cons: lamp of an other era
Would recommend: Yes

Just wonderful!

by Legacy Reviewer, Verified Owner from IL, United States Written on June 22, 2011
I have been looking into this microscopoe for years. I finally was able to view one and immediately bought it for myself. As an entomologist it is important to see very small structures on my specimens so that I can make accurate observations and identifications of the insects I am studying. The working distance is perfect, the images are clear and crisp, and the heft, construction, and durability of this scope is evident. I highly recommend it to anyone, even if they can afford a more expensive brand.
Pros: Clear images, user friendly and thoughtful design
Cons: Lamp gets hot but it does work
Would recommend: Yes

SF-50BA

by Legacy Reviewer, Verified Owner Written on December 13, 2010
I am a knife maker and engraver doing very detailed engravings. I purchased this Lomo scope versus Chinese brands for 2 reasons: when researching scopes I discovered many warnings from other engravers regarding variable Chinese scope quality. Lomo is considered by some engravers as a step up but still very affordable. Secondly, trying to get tech. info over the phone from distributors of Chinese scopes was impossible as they spoke unintelligible english. Optics planet inquiries yielded clear advice and was just what I needed. The 14X eyepieces appeared defective as they wouldn't produce a clear binocular image, however customer service was on par with the claims.
Pros: Great Price for the quality and performance
Cons: None
Would recommend: Yes

SF-50BS

by Legacy Reviewer, from OR, United States Written on May 7, 2010
I am an electronics engineer who often does his own prototyping. The SF-50 gives me good working distance for both assembly and inspection. Exceeds my expectations. Particularly appreciated the extra illuminator bulbs (although LEDs would be nicer).

There is some field curvature at the edges, but I'm very pleased with it.
Pros: Great Value
Cons: Eyecups fall off easily
Would recommend: Yes

LOMO swing arm scope

by Legacy Reviewer, Verified Owner Written on May 3, 2010
Sturdy Russian construction, no continuous zoom rather fixed steps, but does great job inspecting printed circuit boards. Haven't tried out different optics yet. Seems to be slightly better deal than Amscope.
Pros: large working area, mountable many table tops
Cons: prefer LED light, took a minute to figure out eye width adjustment
Would recommend: Yes
