How good is 70D AF system compared to 50D?
« on: July 09, 2013, 11:14:53 PM »
I really just want to upgrade for autofocus, so anyone that is familiar with the 7D's system, how good will 70D be compared to 50D?

Much better at servo tracking. Similar with one shot (too bad the 70D seemingly won't have Spot AF).

Who knows, it could even be better than 7D [CR-100!!!] if we consider that the specs don't tell everything: the non-cross outer AF points of the 6D have been reported to be better than the ones in the 5D2, although the specs were the same.

Just saw in the 70D manual it only has 3 focus types, single point, zone and all points. That's lame. No expansion.

Can you point to the manual link?  i couldn't find it on UK, really wanting to read up on video options.

like 7D vs 50D... at least if not better.

If you want those AF features, why not get a 7D?  I can attest that the 7D AF system is superb, once you get the hang of it.

The 7Dmkii will likely be out of my price range.. But if the 70D has the same sensor as original 7D I assume it'll still be really good

Correct. The manual indicates that the 70D does not have spot AF (not point expansion, which I do use on my 7D for some scenarios of moving subjects).

However it does have spot metering... which at least is better than nothing - I do realise metering and AF are totally different.

There are areas where the 7D (and I expect the 7DmkII) have advanced functionality over the 70D... so that's why I might consider the 7DmkII.

Hopefully the 7D's AF (both optical and LiveView) - will be even improved over the 70D's..... but I do think that now Canon have got it right with the xxD range getting the very good 19pt all cross-type AF system (those who learn how to use it can capture great photos!)

The Rebel/xxxD bodies have spot metering, too. Just sayin'.  ;)  Now, if that spot metering could be linked to the selected AF point...

True... thanks for the note, Neuro :)  Well.. except for the 'older' Rebels like my trusty 350D (XT) - which didn't have that 'advanced feature' back in the day ;)

I agree... I SO much want spot metering linked to the selected AF point... please Canon, are you listening to us?! (Maybe with the 7DmkII????)  So important for many applications... eg BIF.

Neuro, surely with some of us here on CR, we could set up a new camera manufacturing company within a few months and by the end of this year produce a DSLR with all our needs perfectly met... eg a FF 20fps, 500 AF points, clean ISO from ISO25-ISO512,000 (H option up to ISO 5million)? And if we packaged it with this kit lens (50gr pancake, 10-1000 f/0.75 10 stop IS, Super-duper USM) and set the RRP at $298 as a kit to undercut the EOS-M ... well that would work, right?  Anyone?.....

Cameron: But we don't have any money.

Michael: Yeah, well, what we need is a backer.

Cameron: What's that?

Michael: Someone with money who's stupid.
