Hi all,

I'm am currently selecting a camera and camera lens for my Raman spectroscopy setup. About the camera lens, would a longer focal length or shorter focal length be better? For the camera, I am quite low on budget so I'm planning to buy from Taobao...

The specific model I am looking at is JHEM504UM from JingHang (a Chinese brand) which uses a IMX264 sensor. There is another model JHEM1200UM which uses a IMX226 sensor which is significantly cheaper. I'm not sure why as IMX226 seems to have better resolution. Another model using IMX178 is half the price.

Which one would be better?
