Tamron, who have recently been rumored to be considering the production of X-mount lenses, have just released this beauty. I have just written to their customer service department asking them to please produce this with the X-mount. According to dpreview’s comment on Tamron’s press release it will retail for around US$ 800.
If anyone is interested in getting more quality lens choices I suggest you also write to Tamron. Maybe we can show them that there would definitely be buyers if they decide to go the X route.
