I have an application that needs to image something in the range of about 25-35 cm from the front of the lens. I'm looking at the new High Quality Camera with the 16 mm C-mount lens. The lens itself has a focus adjustment and it seems that the camera itself has an additional adjustable back focus:
- Back focus: Adjustable (12.5 mm–22.4 mm)
Question: Right now I just want to know if this combination can focus on things 25 to 35 cm in front of the lens or not, and produce reasonably good quality images.
Using extension tubes to get images closer than the closest design focus of a lens can degrade image quality in some cases, and a bit of that is not a problem. Perhaps an additional extension is possible, but for the purposes of this question I just need to know if these two items off the shelf will allow me to focus anywhere within 25 to 35 cm from the front of the lens.
