Hi. I recently picked up a gently used Quantaray 70-210mm AF lense for my Canon XS. I tested when I got home with it and it was working great. Went out a week later to use outside and it quite working, came up with a ERR01 lense communication issue, I cleaned contacts, made sure my kits lense worked and it did, but the 70-210mm still didnt work. Try trouble shooting the problem, and what Ive come to figure out is it works inside with daylight(natural light) but when outside it does not work. Anyone hear of an issue like this? Or know what this may be and why? BTW- I did use outside with a UV filter on it. Thank you.
