We present a comparison of results from using Padova and Dartmouth isochrones for several open clusters (M35, NGC 2158, M37, M67) in the infrared. Using newly reduced deep near infrared data (J 20), we compare the validity of these isochrones at low mass, and over a wide range in cluster ages. In addition, we combine the new deep NIR data with 2MASS, mid infrared photometry (3.0-8.0 micron) and optical (UBVRI) data to construct a wide photometric set for each cluster. We look for variations in isochrone-derived parameters when using different color-magnitude combinations.
