... was asked of me to be published for easy comparison in terms of size, weight and price (relative to recent prices since I don't update my info every day or week). So here they are, all prices are taken from the Italian Online Market or converted to euro from the USA market where not specified the price in euro (ex: $). Canon & Nikon mounts (including Third Party Manufacturers) that are Full Frame compatible only: Addendum: the lenses written in black bold and italic have some sort of weather proofing (official info). Pentax lenses: Sony lenses: Addendum: the lenses written in bold are compatible with Full Frame mount and the one written in italic are APS-C only lenses. Please note that some information may not be complete or even correct about the availability and price in the European, and specifically Italy, market. I hope this helps in some way people who need or want to make a choices or comparisons. Respect Ovidiu.
