long exposure 5D vs 5D2 (anglais)
pensant eos ces temps ci, j'ai posé une question dans un forum anglais (dpreview).
en questionnement sur l’intérêt un 5D2 dans mes travaux, je me permet de copier/coller mes interrogations.
si mon anglais n'est pas compréhensible, je peux réiterer.
d'avance merci pour votre attention
It is my first post in your community but you seems to be interested enough in camera possibilities to maybe have an answer to my question.
I actually use a 5D (1) for long exposure and lights in movement.
the camera stick the bulb mode and I have (nearly) no other use of this canon.
have a canon background and really happy with this FF DSLR.
print from 60x90 to 80x120 cm (23x35 to 31x37 inches) are good (but i didn't make a close comparation side by side with another digital camera)
even I didn't have any failure with the 5D I asking my self if the 5D2 can be better for my work.
video/high iso ability are not really usefull for me
the 5D2 "improvement" can be for my use :
- live view (all the shoot are on tripod in dark area, easier to focus - manual lenses)
- electronic dust removal (expensive gadget)
- 21 mpxl !, but it is the question
--> will the images be better and will it be noticable on prints
I read in the forum about the "banding" in shadows with the 5D2 low iso, the pixel size
also the dynamic range between canon and nikon (but will not switch from canon for numeric work before MF is affordable)
question is:
I use iso 100 (why not 200 with hightlight compensation), exposure from 2 to 10 mn.
a lot of contrast (search jadikan in google for last year exemples)
5D or 5D2 will give the best result in printing 60x90 cm ? 80x120 cm ?
(23x35 to 31x37 inches)
the question is focus in term of long exposure noise, the hot pixels are commons
I had already had a look to the camera file comparaison but they always use a short exposure time.
If someone have an idea, have alreday done this type of long exposure test or have the 2 cameras, please drop a line.
