You will need to focus manually. Even with the 1.4X. And thus you would need to be on a tripod with a good head like the Mongoose M3.6. In general, I would not recommend the use of a TC with that combo. If you insist, go with the 1.4X. If that, please use this link:

If I purchase the 2x converter would the images be sharp.? I have never used a tc so I was wondering before I buy.
