Lenses / 70-200 f/2.8 II + 2X converter versus 100-400 f/4.5-5.6

« on: October 20, 2012, 11:44:42 AM »

I rented the 100-400 mm for a trip to the San Diego zoo, and thought it was a really nice lens. In terms of utility, though, I'm not sure I have a day-to-day need for it (though need & want aren't always correlated).

As I already own the 70-200 F/2.8 II, I'm wondering if getting the 2X converter is a viable option.

I believe Neuro has previously written that the quality of the 70-200 + 2x is comparable with that of the 100-400. Does anyone have any experience with how fast/accurate the AF when compared?

Moreover, has anyone made this decision before and either been really happy with it or wished they'd made a different choice?

Thanks

EOS Bodies / Re: 1DX lock up?

Thanks, exphose. I had also written a Perl script that copied large files to the card until it was filled. Didn't run into any issues with the card. That, of course, doesn't rule out weird interactions between the card and camera.

But I'll note that I've not seen the issue with the replacement 1DX I have (knock on wood) using the same cards I had before -- I've even filled them up during a shoot.

I suspect it has to do with the circle of confusion calculations: http://en.wikipedia.org/wiki/Circle_of_confusion

Here are CoC values for some cameras: http://www.dofmaster.com/digital_coc.html

The more densely packed the sensor, the smaller a circle of confusion you can resolve, the smaller the DOF (hoping I parsed that right; figuring if I didn't, someone will correct me, though

Seems the 32 GB LEXAR 1000x is at least a small factor in the lockups! maybe that's why they are ON sale at BH.

Maybe. Card I/O is asynchronous, I wouldn't expect it to lock up the camera. When I saw the issue, the shutter got stuck open. Thus, I wonder if perhaps the new shutter mechanism might have some quirks that haven't been fully worked out, or if maybe some of them have manufacture defects.

As a note, the lock-up seen here has happened with both Lexar cards (me, 1000X cards) and SanDisk (Mark). Here's his post:

The red light was on for almost the entire shoot, I'm using Sandisk 64gb and 32gb Extreme Pro cards.

For those who have to send the camera away for cleaning, how do you pack it? And then how do you ship it (UPS, FedEx, next day, etc)?

I live in the bay area, and the closest Canon service is near LA.

I'll admit that physically sending my camera somewhere seems unsettling to me.

Thanks.

Not sure everyone would find this useful, but a friend's camera has the ability to set minimum shutter speed as a function of focal length (e.g., 1/f). Seems like a big benefit for non-IS lenses. Though, this could just be my lack of skill

Wow, I totally misread your first message, Victor (I missed the "need" part). My bad

If you don't mind sharing, what methodology do you use when you clean?

Thanks, Drew & Victor.

Is there a Canon location near you, or do you send it in?

Sending it in seems very, very unappealing to me.

Also, I've heard some people mentioning getting their camera back with a sensor as dirty as it was when they sent it in.

If you don't mind me asking, which Canon facilities have you had good success with?

FWIW, I'm in the San Francisco area.
