Brand New Sigma FP-L Hybrid L-Mount Modded with 4'Astro
Sigma FP-L Hybrid L-Mount Modded with 4'Astro. 24-month warranty. AF recalibration, focus achievable at infinity with all lenses, and white balance reconfigured.
The original filter has been removed and replaced with the excellent Astronomik L-2 filter for EOS 4'Astro. The sensor has then been carefully repositioned to maintain autofocus functionality and preserve the "daytime" performance of your camera.
With this modification, you'll finally be able to engage in telescope photography or use camera lenses under conditions previously reserved for dedicated astronomical cameras.
The original filter has been removed, and the 4'Astro filter we installed enhances the camera's capabilities in the red spectrum, allowing you to capture nebulae (Hydrogen Alpha emission line) under the best conditions.
You can use this camera in everyday life by adjusting the white balance settings that we include in the mod, and the exceptional characteristics of the 4'Astro filter will allow you to enjoy your camera in all situations!
The sensor is repositioned with extreme precision using an optical bench after the modding process to ensure perfect orthogonality of the sensor with the optical and mechanical axis of your instrument, and to optimize autofocus performance.
Technical Information
Apart from the replacement of the original filter, the camera's characteristics remain strictly identical to those of the standard version.
These products are sold exclusively by EOS FOR ASTRO . All orders will be handled, processed, and shipped by EOS For Astro.
Please note that the original IR-cut filter may not be returned as it can sometimes be damaged during the modding process. The Astrodon Inside mod alters the camera's white balance. However, this does not render the camera unusable for daytime photography!
To achieve proper white balance in everyday photography, you can follow our short tutorial video and see the before/after results on our White Balance page.
