Night Vision The Official: Steiner C35 Thermal Clip-on Review and User Thread!
- Thread starter TheHorta
- Start date
Don't worry, that might not mean anything. The Gen 1 was also only available in Germany as an objective mounted clip-on. So there could very well be different versions for different markets.
Gen1 is 640 with their "quantum vision" core. Not sure if they have updated/changed the actual sensor for the Gen 2. Core resolution is the resolution of the sensor, higher=better.
I have a Gen 1 C35 and I love it besides the weight.
The weight of the Gen 2 is listed as 460 grams, so that is a significant reduction compared to Gen 1.
Sensor resolution and pixel pitch have stayed the same 640x512 @ 12 um, but NETD has decreased, supposedly below 30mK now (50mK for Gen 1).

Like @tam4511 said, higher = better for thermal cores. However, the lens that is used also makes a difference (and directly impacts field of view). With thermals, you are trying to balance resolution with field of view. For example, a 640 core can be used with a 35mm lens (like the C35) for a 12.5 degree FOV, or the same 640 core can be used with an 18mm lens (like the NOX18) for a 24.3 degree field of view. The same 640 sensor could be used with an 83mm lens and have a 5.3 degree FOV. Of course, the narrower field of view gives you better viewing range at the expense of how much area you can see.
As you can tell, the larger the lens, the narrower the field of view. In the example above, the sensor was the same size (640), but a different sensor size would yield different results. In ballpark numbers, a 320 core will have half the field of view as a 640 core with the same lens. Pixel pitch can also impact the overall size of the sensor which changes the size of the lens needed to achieve a given FOV (a smaller pixel pitch allows for the use of a smaller lens to achieve the same FOV).
Hopefully that is more helpful than confusing
Thanks fellas. Appreciate the quick education. I found the following article explaining the importance of lower NETD values. It has pics of a <35 and a <50 example. Pretty big difference in thermal detail.

The Importance of Thermal Sensitivity (NETD) for Detection Accuracy
As users continue to expand and evolve their security systems, the adaptation of thermal cameras to improve their overall situational awareness at the perimeter has been a growing trend. Because more visible camera manufacturers are introducing thermal offerings, it is important to understand...
Who’s gonna be guinea pig?
In stock at 3,000euros
I think you got that backwards because there doesn't appear to be a rail interface in those pictures
And in the description under "Mounting Standard" it says "no"
I'm thinking that is still just the Euro model. Can't imagine they would replace the original that sold so well in USA without the clip on rail mounting. That would be a huge fail for this market.
Definitely, when the gen1 first came out it came with a bell mount
The NETD on that Euro model is <50mk. Hopefully the US model will be <30mk.
Where can I find adapters for different sized objective lenses for mating up to the C35?
Those for sale now are only in Europe.
I have no experience with these (yet) but from what I've read you are waaay better off to cool your jets and wait for them to come to the USA market when they are expected to have the standard rail mount. I think thats what happened when the first iteration came out. Euro first, then to the USA with the rail mount.
The EP Arms bayonet adapter is one solution, the others are the Präzise Jagen Duo (https://praezise-jagen.de/de/55-duo-verbinder) and Rusan also has a bayonet style version now called the MAR (https://www.maximtac.de/rusan-mar-modular-verbinder-vorsatzgeraete.html).
Where are you located, if I may ask? I'm in the Nuremberg area.

If anybody is looking for a clean light blocker between your scope and the Steiner, I paid a whopping $8.28 delivered for this off of ebay.
The scope shown has a 44mm objective.

So I know this is discontinued but I have seen a few for sale.
By now I'm sure someone has got a decent amount of hunting hours behind this, what is your final opinion?
I'm deciding between this or a dedicated thermal
such as a AGM ( in the price range).

Don’t own one personally, but my two main hunting buddies run them. Solid piece of kit, especially for the ExpertVoice deal they got them for. Heavy. Image is damn good though out to 300.
Are you saying its good for identifying out to 300?
It's..... Ok. Deer and calves look similar at times.
PID at 300 it’s a coyote vs neighbors dog? No. Coyote vs hog vs rabbit vs skunk at 300? Yes.
Do y'all find that any other 640 thermals, under $10k, have substantially better PID capabilities?
I can’t speak to collimation or return to zero as I didn’t test those abilities. But I did test on a particular cool evening and was able to definitively place crosshairs on an adult male (human) at 800 yards.
IF the return to zero is solid, 800 yard shots are possible with this unit under fairly favorable conditions.
That “if” is significant, but it’s impressive none the less.

Every 640 BAE core thermal under 10K has substantially better PID. But if you’re talking clip-ons, this is definitely the price/performance value king.
The Bering clip-ons have excellent image performance but are slightly more expensive.
The Theon units sell used for under 10K (except the ELR) and beat the Steiner’s image… if you’re willing to gamble with that company.
I've got 4 batteries for a C35 I'll send to someone that wants them
Thanks! The C35 is my first and only thermal so far. So I'm not well versed on performance differences.
I will be happy to take these thanks. PM sent
Would you say this would be a better thermal than the AGM 384 ( same prince range)
You should buy that $1900 C35 immediately. That is an amazing deal. These devices punch way above their price.
Arrived on Saturday evening.
Maybe I can convince Steiner to send me a picatinny mount.
I used the Steiner and a Krypton 2 50 mm Clipon for the last 2 weeks extensively.
Both are used with a Buris RT6 and Rusan Modular Adapters.
Both are quite nice for identification of wild boar and roe deer.
The latter I’m not allowed to shoot with it though (local regulation).
The Steiner eats up batteries like crazy though. I don’t get more than 2 - 3 hours of use out of one.

I've been designing/testing the beta versions of a mount adapter that adapts the S35 mounting system to an ADM mount. Other than moving everything forward to bias the scope to the front of the ADM mount, I think I've got everything else figured out. I've used my prototype a few times now and everything seems to work nicely.
I've been using xometry to get my one-off parts. If anyone knows of a shop that can make these for a decent price, let me know. I'm tired of paying 200$ a piece after 3 or 4 iterations.
