PowerShot Cameras / Re: Will Canon ever make 1 inch DPAF sensor?
« Last post by RGF on Today at 03:07:37 PM »
Can someone explain to me what a 1" sensor is?  Is that the diagonal measurement?  Or something else?  Is there a good website that explains all this stuff?

Thanks

Rich

Thanks everyone!  Sorry, my net has been down for a few days, hooray for phone tethering I guess.

Third Party Manufacturers / Re: Leaked: Sigma 105mm f/1.4 HSM Art

That represents almost the entire non-white L prime lineup -- including fringe-ier items like 20mm and 105mm -- knocked out in less than 6 years.

I'm sure that Sigma has used their existing lenses as a base for improvement, and I wouldn't be surprised if there are some design similarities between the 135 and 105, for example.

Some of these have probably been in the works since the pre-Global Vision lens series were released.

That 105mm might be similar to the Canon 200 f/2 in size and weight.

Starting at 1.4 means with a pair of doublers it can be a 420mm 5.6. hah!

EOS Bodies - For Stills / Re: AF setup help needed
« Last post by Viggo on Today at 02:50:28 PM »
Did just that but with a 5DmkIV. AF Case 1 with default settings and initial point autoselect works well enough for me. Straight on at 15-20km/h can get tricky at f/1.4 and 3m distance but for me a third in focus is acceptable at such circumstances. In really heavy snowfall, lower tracking sensitivity. Dunno which af case that needs though.

Thanks!

Auto initial? So you use all 61 points with color/face tracking? I’ve tried that also, no luck. I’m thinking this might be one of those scenarios were nothing works, because usually it’s very very good...

Sorry, wrong wording. I've got spot af as default on shutter half press with af-on doing all-point auto select based on subject at the point that was active. If I can't keep up with motion and keep a single point on target, I have a single button for my thumb to make the camera do Magic for me.

Ah, that makes sense, I use af on for af, but use the *-button for a different AF set up.

Surface Book has an exceptional screen. As an added benefit, you can detach the screen for a very nice photo viewing tablet.

But it is very expensive, and cannot compete with gaming rigs for CPU power.

I'd like to hope it's better than ti was before, because the 35 art is unuseable and Sigma refused to do anything about it. I'm now stuck with it because I am unwilling to pass on this piece of junk to anyone else.

Would be great if someone came out with an equivalent of this lens with autofocus.


And yes, I know what the specs say, but this is a Sigma. If my sigma art 35 lens gets focus right 50% of the time then it's a really good day.  Doesn't matter how great the optics are if the autofocus is junk.

The 35 and a few others used a much older AF motor and algorithm and the later models are quite impressive. Some rival 1st party such as the 85 and 135 not to mention the 24-35 as well for an older model with good AF (easier on wide , I know) It really is night and day.
