no... cos i am going to taiwan this coming 13th.. and there weather is cold.. during cold weather is better to not to take out the lens in cold weather...:bsmilie: thats why
My personal opinion and experience should be fine. I did that in Nov in Vienna. It was like 5 degrees in the morning. I just changed my lens in the open. Just have to take care not to drop any of them on the floor.....heart pain......The other thing for you to be aware is that if you are changing the lens, do not do it when you move from a warmer place to colder place immediately. Just give it a bit of time to stabalised the temp. Otherwise you might get condensation................
Have fun
