Sharpness testing with Canon 50MM 1.8.....a bit weirb i think ?

[DeSwitch]

maybe at the same time can use the back-focus test chart method. I tested mine and result was good.


Cant remember wher the tread was. do a search for it.

You can download the focus test chart here. It's for D70, but can also be used for other camera.

i did a test on my 50mm recently. can do a search. and i recently shot my friends bday party with just the 50mm prime alone. my verdict - it can be really really sharp at f/5.6. usable at 1.8. very nice at 2.8. wonderful at 5.6

Best apertures for sharpness are around f8 to f11.

What is your shuttle speed? Should be quite slow as it looks like the lighting is dim.

You may want to try to use flash and retry.

 

[Snoweagle]

Perhaps can use manual mode too.

turn up the lighting in your room. it looks pretty dark, and that may result in the slow shutter speed causing the blurrness...

 

[Snoweagle]

Can try to increase the ISO setting too.

 

[ConnorMcLeod]

What mode were you using?
i.e. Av, Tv, M, or P ?
I can imagine one possibility is when shooting in Tv or P, you change ISO and aperture size reduces.
Try Av or M insteads.

 

[Snoweagle]

For indoors use a higher ISO and M mode, unless u have a tripod.

I had my test with 50mm f1.8 as well and it shows that it has some consistency problem. 3 out of 10 time will have exteremely bad focus.

I'd recommend to use flash, 1/100s, and on a tripod for more controlled test environment.

Btw does anyone has picture of with their 50mm shot on test chart and faraway building? I suspect my camera has sensor calibration problem (or could be the lens too) which results in not so sharp image.

I'm using film and have taken many shots with my 50mm f1.8 II on different locations, if not i can show it over here.
