lens too fast ?? at DVinfo.net

Bart Wierzbicki · January 21st, 2010, 09:04 AM

Hi,
I have already a 7D and I use my old nikon primes on it.
Now I will be buying another 7D and maybe with original canon lenses.

Everybody is saying the best is the 1.2, but do you film a lot on f1,2 ?
I do a lot of wedding reports and sometimes f1,4 is already too shallow.
Which lens do you suggest ?
The f1,2 is too expensive, so what do you think about the 50mm f1.8 ?
Is that a good alternative ?

I was close to buying the Canon 50mm f1.2 but decided to settle on the 50mm f1.4 instead. I was using a friends f1.8 which was ok but the 1.4 was the one for me. The 1.2 got such bad reviews, it was a no brainer (for me).

I would have to say, go for the 1.4, you will have over all happiness with that one, the 1.8 has its moments and the 1.4 is at a reasonable price too

No, it's terrible. The manual focus ring is not a ring at all, but an instrument of torture sent by Canon to punish those who focus manually. The Canon 50mm f/1.4 is OK, but the Sigma 50mm f/1.4 is better still.

Hello Bart, could you tell us what adaptor are you using for your nikon lenses? and how do they work on the 7D?

Thanks

Hey Manuel,
I have the adapter from Cinevate (Cinevate: DSLR Rigs, Camera Sliders, Follow Focus and More).
It's kinda cheap and I think it's good value for money.

Get the Sigma 30mm 1.4 or even better, the Canon 24mm 1.4.

1.4 is almost a full stop faster than 1.8 and with a wider lens, your DOF won't be as shallow.

Here's a great online resource for calculating the DOF for any camera or lens combination:

Uhhh, what?

Lance Watts · January 26th, 2010, 07:17 PM

The difference between 1.8 and 1.4 is 2/3 of a stop. Do you disagree with that?

Ohg my goodness.... you're absolutely right... my mistake.

I've seen your posts around, Perrone, and I know you're a knowledgeable guy. You had me second guessing myself. :)

So, to reiterate, Bart: Get something fast and wide. And yes, there's a big difference between 1.8 and 1.4. At 1.4, 67% more light is reaching the sensor.
