Title: How good is 70D AF system compared to 50D?
Post by: IceAgeDX 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.

Let's see - my early release of the 70D tells me - oops can not say anything since Canon will cut off my xxx if do.

You will need to wait and see what the review tell us.  Until then, it is simply guesses.  My guess is that the AF will be better than the 50D by a good bit and slightly ahead of the 7D.  Remember you heard it hear first.  If I am wrong, you can cut my pay in half; if I am correct, how about doubling my salary  ::)

? Heath Ledger. No candy bar in Australia that I know of but now we can eliminate me and Heath if my guess was wrong

We have a winner...for the male lead, at least.  Now...what's the film?  BTW, the actor is from Oz, but the candy is from the US: the Heath Bar (http://en.wikipedia.org/wiki/Heath_bar).

The part of Cameron was played by the actor that played an alien named Tommy in sitcom named based on our place in the solar system.

I wonder how many months I will play trivia in the forum before I get my new camera?

I think the 70D will have a better sensor than the 7D, at least based on the specs:

7D

70D

Based on these specs, I think your 70D is a better by.  And not wanting to start a holy war, I will say that I've never been impressed with the 7D (you can look back to some of my first posts here on this forum), and truly believe it is a lemon (http://www.michaelmiles.com/2011/04/25/is-the-canon-7d-a-lemon/). 

I'm one of the few (probably <5% of users) who never got a sharp photo from a 7D; and started hating photography because of it.  Yes, I'm a pixel-peeper, and yes, I'm an OCD photographer.  I want my images to be tacky sharp.  So maybe I'm not a fair example of the average 7D shooter.

But in my limited experience with only three 7D bodies, each one failed me with its poor AF.  Pretty much every shot I got from a 7D body resembled the infamous Darwin Wiggett "melted-hay" photos (http://darwinwiggett.wordpress.com/2009/11/11/the-canon-7d/) at 100% view.  After months of swapping bodies with Canon Irvine, I finally parted ways with my 7D.  Since that moment I felt as if the heavens opened, and I became a sane photographer once again!  :P

However, I am excited about the prospects of a 7D MKII based on recent rumors posted here on CR, and anxiously await its announcement.  I'm sure any AF issues have been resolved in the 4 years since the original 7D launched.
