My first Moon shots

Did my first moon shots with Joey's EF 75-300mm f 4-5.6 at 300mm. Played around with the exposure settings for a while and got the correct after 3 shots or so. One very noticable problem is that the image captured doesn't seems as sharp as those posted by other people.

Next day, decided to check with daniel to borrow his EF 400mm f/5.6L USM with a Extender EF 1.4X. On that night, upon setting up my equipments n stuff, I tried to Manual Focus via the viewfinder and *Woosh* I was totally surprise to see the sharpness difference already... no doubt it is canon's Top of the range L Series Prime lenses... Took a few shots and add in the 1.4x TC moments later. I was actually expecting to see slight image degration with the TC, but No~!... the TC brought the moon closer, but MF is still tac sharp. Took a few more shots and am totally pursuaded that THIS L lens is really good ( or Joey's 75-300 is really bad ).

Below are some shots taken. All with Contrast and Brightness adjusted in camera for + 2 stops, and Level and curve adjusted and cropped in Photoshops.

Image not sharp at all

I can actually see the craters on the moon even using manual focus, no doubt one of the sharpest and cheapest Super Tele canon has.

With a 1.4x teleconverter mounted, the image is as sharp, no much image degration. It brought the moon much closer and make manual focus easier.

Same equipment, different exposure settings, but mostly around 1/400sec + F/8, plus minus 1/2 a stop in both shutter and appeture.
