No, it's a magnetic lens. The TG7 also doesn't have a screw thread. I'm sort of hoping it will fit on my TG3 as well, but as new model is smaller (slightly) dimension wise, I'm guessing probably not, but live in hope until i can actually try.
I think that's really off of Sony to not make one for the TG3 if thats the case. It's obviously possible, they've sold a shed load of Tg3's....any trick to get the consumer to upgrade..
I wouldn't be too surprised if the S*ny magnetic adapter fits the TG3, too: changing the size of the lens housing would mean making new parts, and Sony have been on hard times of late so my guess (without actually comparing the specs or physical dimensions) would be that the TG3 and TG7 lens diameter is the same. Can anyone confirm or deny?
Also, there's information here on getting around this potential conundrum by making your own magnetically-mounting wide angle lens adapter.
I rang a helpful chap at Sonystyles online ordering/help number-he went and spoke to a technician who reckons wide angle lens WILL be backward compatible with TG3. I bit the bullet and ordered one. Will arrive in 5 days, will post back result/if fits.
