Greetins friends! I recently took five rolls of slide pictures of my
daughter dancing with other members of ballet school. Pictures were taken
with flash as it was a dress reharsal. Lighting was very poor. Exposure
without flash was f2.8 and 1/90 sec. Fifty percent pictures came OK. I used
ZX50 with FA 135mm f2.8 lens & external Pentax 220T flash and Provia 1600
ASA slide film. I used aperture priority system. Aperture was f2.8. I was
about 50 to 60 feet from my daughter. I checked the flash expossure with OK
check light at back.
I had noticed two problems. [a] During dance the girls [about 10-12 girls]
were moving around the stage. Sometime my daughter was half hidden by other
dancers. Will the camera with spot focus like ZX5n or PZ1p [if PZ1 or PZ1p
has spot AF] will help in this situation? How quick the spot AF compared to
AF speed of ZX50. AF focusing of ZX50 is very fast.
[b]I was afraid of camera shake with 135 mm lens plus external flash.
Highest flash sync speed of ZX50 is only 1/100 sec. Will PZ1p with higher
sync. speed will help? Flash light duration is very small. Does it matter
whether flash sync. is 1/100 or 1/250 sec regarding camera shake.
With thanks.
