bought the 50mm F1.4
playing around with the "F number" all day. lots of fun!
found it very nice & easy at shooting the "big head" photos & "half body" photos.
still working on "full body" photo...any hints?

off topic question: is this 50, 1.4 len capable of shooting kick-boxers (fast moving humans)?

Do you know all AF Minolta Lens can fit into your sony Alpha camera, don't just limit your choice to sony, and I think there are many good minolta lens on EBay

What difficulty are you having with full body portrait?  Don't you need to just stand further back?  Maybe you want to tell us what problem you're having.

You lens is absolutely capable for fast moving subjects...just use safe shutter speed if you want to freeze action, or if you want motion blur, then use slightly slower than safe shutter speed.

oh, atm, i am not a skillful photographer(fact).
the big head & upper half body photos r like, quite nice(according to noob like me). i mean the background defocused so smooth like cheese(pretty colorful that i can't even tell wat it is). and teh face part is pretty stands out(in focus) of teh photo.

however, i dunno why. when i do teh full body photos, all of em r like(ugly photos). i mean teh background only defocused a little bit(very slightly). the blur effect just like not enough... and i dunno why the photo like in focus below waist & defocus above neck(the face part doesn't stands out).

all of the pics were taken during sunny day(3:00pm ish), i usually stands 5ft - 10 ft away from the target(5ft girl). i didn't use a tripod(had the anti-handshake function on).

hmmmm, i think i need more practice..

off topic question: if i print (16x20) & (24x36)photo with the 3872 x 2592 jpeg file, will they look good?
or which size(print photo) is optimum for 3872x2592 pixel ?

   why people want blur effect ?/

I think now ..  most people want to see SHARP clean pic ??

Doesn't matter that day time u take the pic . . if you want blur background ..   u better use PS to process ..  or get a soft filter ..  or get a soft lens .. or get a lens baby ..

if you stand further back (i.e. full body shot) the background blur will be less even with the same f stop.  Try to shoot at max aperture.

daimo

The longer the focal length and the larger the aperture the more shadow the DOF, i.e. more blurred backgroud.

In other words, if you use a wide angle then it is much harder to achieve blur background then a telephoto.

canon10D

if you want full body with bg blur.... u will need a tele lens......

but wide angle lens can do the same effect but not full body shots..... b/c you have to be really close to the subject when using a wide angle lens with blur bg....

I was using my Ricoh GR Digital (wide angle la....)and I can still get the bg "ok" blur --- f2.4 of course.....
