"Who am I to doubt you Doug? "

I didn't mean this as a sarcastic remark Doug, in fact far from it. I respect and value your opinions and advice, they certainly have helped me to become a better cameraman.

I will still put my lenses through a test, just so I know where the sweet spot is on my equipment.

Cheers :-)

Don't worry, I took it the right way. I'm sorry if I sounded like I didn't get it. Everything is cool.

I would be keen to see those test's screen grabs to see if my own EX is in the bounds of sharpness.

Glynn, put your camera on a sturdy tripod and shoot 10-20 seconds of material at each aperture. Use a Progressive mode rather than interlaced. On my tests I usually say the the settings so when I play back a clip I know what it was shot at. Try the same sequence of tests under soft and strong lighting.

Although all the advice is not to go beyond f8, shoot some footage at f8, f11 & f16 if only to open your eyes to what the results will look like.

Have fun.

I will post my tests later this week, have to finiish of another assignment first.

At the end of this video there are some examples of diffraction limiting.

I found a room, stuck a focal chart on the door and did the aperture sharpness test. Really cool to see the theory proven. f8 and f11 aren't too good.

I noticed my Mid shots at f2.8 and f4 were a bit blurry though, don't know why that could be.

Thoughts?

f4-f11

only showed WS of f11, cos you can see it so clearly.

These are JPEG files but they are the same res and are identical to the eye to the BMP's

Think my camera is up to scratch?

PS: I know my WB is completely out of whack - i should have reset it.

Selling

I'm now selling this Ex3 for an overseas opportunity, but I do need to know if these are acceptable back focus images before I sell it. I don't want to sell someone something that needs a service.
