Billy bbbuttie... both standing side by side cannot have the same composition and frame... coz FF and Crop FOV ish different mah... to have the same, crop shooter have to stand further back in relation to 80mm & 50mm different...so the focal length DOF will have variations and DOF ish de cause of bokeh.

even if focal length for dx and ff is corrected to get same fov..ff sensor will definitely renders a more creamier bokeh..

i like to read.. but i will not 100% trust what i read ... but i won't 100% reject what ppl comment lar... must do some test first mah..

chiu can pass me ur 5D markII i test por chiu :devil:
 

no over react buttie... smooth bokeh no doubt is nice. But i think those bokeh talk is just hao rianz abt their equipment... Take a 50mm 1.8 and a 50mm 1.2 of course 1.2 win but if a person take 1.8 and shoot better composition than a person taking 1.2 then tat 1.2 person shld throw away his lens and join Tangeaters to eat instead bah... :bsmilie:

dun throw the lens away la, let us experience with it or use as paper weight.
it's true some people juz talk hl abt their lenses and equipements..
there are people who simply take very nice pictures no matter wat kind of camera they used...
 

hmmmm, they din digged ur check in luggage? maybe it's only some countries they will do tat.
tank chiu all for the infor

depends on the air line if the letu bring up the tripod on the plane.

reminds me of 1 model shoot i attended..

photog innocent: Wah ur image swee, bokeh very swee..
photog L1.2: Because its a L lens and f1.2
photog kit lenz: wah nice bokeh
photog innocent: Wah ur portrait shooting is good! no bokeh oso nice!
photog kit lenz: where got? i first time join model shoot.

Morale of the story..talent is in born, u can learn to be better. But still doesn't makes u a talent.

I have seen that thread...
and it is very confusing in a sense that it is not easy to understand optics.
We are cool, just friendly discussion nia.. :)

For a same lens ( say 50mm ), if you mount onto different body, you are only seeing part or portion of the image circle produced from this lens.

imagine a portrait shoot.
Scenario 1:
all standing the same distance away from the subject
using medium format will let you shoot a full body of the subject with 50mm lens
using FF format will let you shoot half body and
using cropped sensor will let you shoot head and shoulder only.

The amount of bokeh is the same when all is using the same F-stop and because distance from lens to subject is the same.

Scenario 2:
medium format is standing 3m from the subject and is shooting full body of the subject.
FF format is standing 5m from the subject and is also shooting full body of the subject.
cropped sensor is standing 8m from the subject and is also shooting full body of the subject.

The amount of bokeh is different when all is using the same F-stop. Because the distance of the subject is different. When your subject is nearer to you, you tend to produce better bokeh ( this is optics ). This can be easily felt when you are shooting macro..... the macro subject is so close to your lens and even at F16, slightly mis-focus and your subject is blur already.
 

even if focal length for dx and ff is corrected to get same fov..ff sensor will definitely renders a more creamier bokeh..

Yeshz...blazy bbbuttie, the specified Circle of Confusion for a crop @ 1.6 = 0.019mm and FF ish 0.03mm, and based on the formula for DOF calculation,

Dn= s(H-f) / H+s-2f
Df = s(H-f) / H-s

where H = Hyperfocal distance calculated based on the circle of confusion. Hence there is an advantage in the FF with regards to background blur...
