We present gravitationally lensed candidates from the Hubble Space Telescope (HST)/Wide Field Camara-3 (WFC3) images of the Cosmic Assembly Near-IR Deep Extragalactic Legacy Survey (CANDELS). In the early imaging data, we find two candidates in the GOODS-S field. GOODS-S1 is newly discovered while GOODS-S2 was previously proposed in a previous lens candidate paper (More et al, 2011). GOODS-S1 has a foreground photometric redshift of 1.135 while GOODS-S2 has a spectroscopic redshift of 1.02. The candidates were modeled, using CANDELS WFC3 data, as compact Einstein ring systems. From our models, we have GOODS-S1 with an Einstein radius of about 0.54 arcseconds with a magnification factor of approximately 100 while GOODS-S2 has an Einstein radius of about 0.5 arcseconds with a magnification factor of approximately 20. More lens candidates will be studied and presented as CANDELS coverage on the sky expands to other fields.
