Hotspot Performance

Slightly sharper than the compact f/2.8 version, it also has slightly less hotspot, but it's a lot bigger, a stop slower and takes considerably larger filters. This lens suffers from internal reflections when using external filters (see samples below), so internal filters are recommended if the option is available.
