Lenses range

PostMon Oct 15, 2012 5:35 pm

I wonder what other people think of the EF lenses range with BMC.

As i'm really green to cinematography (no experience at all)
i have not figured out what would be ok setup for different situations.
lets say 3 setups like bare minimum, average and full lens kit so to say.

Ok it would be simple to look "real" lenses setups and calculate from there
with relative crop factor but i have not got so far.

Would it be good idea to have some sort of chart for that i.e.?
regular 10 mm translates to 23 mm on bmc and you would need to have
lets say 18, 25, 50, 75, 100 etc lenses setup and it would translate
to xx, yy, zz on normal lens to use with bmc.

I bet there are some more people as green as me and have figured something like that would be
handy to set up first lenses setup for bmc.

Hi Margus,

I personally found these links to be really useful:

Margus, there is no solution that fits all purposes. You have to find the lenses that are suited to your needs including the control or lack of control you have over staging and lighting and the range of distances from your subjects. The pros would know the field-of-view you need to support since that's going to vary so much. For example, are you shooting in a large arena or stadium but want the ability to do close-ups? You get the idea I'm sure. What will you want to shoot and in what conditions?

Also your own style is a factor. Do you favour wide shots from short focal lengths or do you like the look of mild telephoto shots? If you can't control the distance to your subject, your set of lenses will be larger to accommodate very tight takes such as inside a car.

Do you require zoom lenses to cover the range of focal lengths or do you shoot with prime lenses? Going beyond what you are asking regarding focal lengths, you need to think if normal 'still' lenses will work for you or if you want ciné lenses. And do you want lenses that are totally manually controlled or lenses with automated electronic controls? Give us a few hints. Even the camera mount is an important hint. Are you buying the BMCC EF or the BMCC MFT or both? That can make a difference regarding your options.

That said, if you are using primes (with minimal breathing on change of focus), I'd think this is a possible answer:
Starting prime lenses (pick 3): wide 12/16mm, normal 24mm, portrait 35/50mm.
Fuller lens set (pick 2): add wide 8/11 rectilinear, mild telephoto 50/85mm.
Full lens set: fill in the gaps as needed to cover 8mm to 200mm (or longer for stadium sports/music(.

Zooms (if possible use lenses with fast constant aperture throughout zoom range)
Start: 8/11-16, 17-55/70mm.
Fuller: add 70-200mm.

i do not have any speciffic needs now on short end yet and i have no experience
with cine ones also. my plan is to get "basic" set of lenses starting wide and go up as far as i can.
will look also to cine lenses. they really interest me even the ef ones.

what i will get for long shots is canon 70-200 ver 2 that is now available.
it seems really sharp from the center to out on charts. different question is if
it is needed to be pin sharp for filming. we will see.

I know that it all depends on so many details what you choose and what you want to choose
out of experience. Now i have been more like colorist and time to time as a producer on set
as we do spots but now is time for me to do some cinematography to myself also :)

i see your point really well to the set to start with and then go and expand.
what do you mean by prime here? EF prime is not the same as cine prime ?
i probably would stick to canon L series now but i will see what i figure out of the
sharpness charts.

what i also consider is to get fastest glass that i can and have variable nd in front of them.
then i could control it by nd or shutting it up as needed to play with focal length
but have possibility to go really open if needed.

at the moment i do not see matte box as good option to start with.
this is why i lean to variable nd. seems more compact also and simpler to implement with ef.

I try to dig a bit and post my findings here to see if it is all silly or going any good direction.

To come back with comparing chart i will then try to make one just that
it would be really simple to visually see what you ma want to have on bmc
and to what it will correspond on regular length numbers. i have not yet seen
something like that here or on web. ok i have not looked yet very long time.

Thank you both for the input!
