EOS Bodies / Re: Canon 70d center focus point -bug- problem
« on: August 07, 2014, 02:34:30 PM »
I've made some more tests with Canon 50 1.4 and Sigma 105 2.8 OS Macro.

With 50 1.4 - good on close distance, bad central focus point with distance more than about 3 meters.

Even with Sigma 105 the problem with central focus point is there at distance.

Here is an example with 50 1.4:
Central point:

Other point:

It's a huge difference, many of images taken at central point focus are not usable.

I have 70D and yesterday I have encountered this problem with central focus point.

Sigma 18-35 1.8 lens:
Central point at 1.8, more than 50% miss
Other points at 1.8, less than 10% miss

I'm very disappointed.

How have you set the AF menu options up?

Which AF Point mode are you using?

And AI Servo? AI Focus? One Shot?

I ask because there's a recurring theme in these discussions of user error...

Here's the thing. All cameras AF (and meter) wide open: so if every single time anyone presses the shutter button your lens is wide open, how is this "problem" not manifesting at any aperture?

Yet the people who reckon they're victims seem pretty clear that it's "only" at maximum aperture as they've set it. How can that be?

It strongly suggests a flawed testing regime, the normal impact on DoF of shooting wide open, and unrealistic/uninformed expectations. I've seen no evidence to support any claims that there's a ubiquitous design/production flaw in the 70D.

Some obviously faulty individual cameras? Yep. Lots of user error? Yep. An inherent flaw in the camera. Nope...

I have checked few times - One shot focus, near and far distance. Liveview is fine, other focus points are fine, central focus point - crap.
And the DOF on crop 18 1.8 few meters away is not a hair.

Of course I will do more tests with other lenses, but for me this is strange issue,  and I bought 70D to replace my 60D for better focus...

I'm CPS member and I'm awaiting their answer what are the possibilities.   


P.S. Totally agree about the lack of fast lenses for most of the 70D owners, also many of them are probably using Auto AF, AF zones or Liveview.

EOS-M / Re: Adapters + legacy lenses on the EOS M: any advice?
« on: July 23, 2014, 10:23:08 AM »
You seems to have good lenses, so if you look at old film lenses should be something really unique.
I have Canon 40 2.8 pancake and even with adapter is small enough for M.
You can also wait for native 50mm lens for M.

EOS Bodies / Re: Eos7D mk2, How EXCITED will you be if . . .?

If we have 70D for base(NO fixed screen):

THE BEST APS-C sensor!
Optimised AF + F8 at all crossed points.
8-10 FPS with large and fast buffer.
Dual SD card slot with latest UHS-3 Support.

- -
Something like EF-S 40-120 2.8
Less than 6D price.

I have Sigma 100-300 F4 which is good with 1.4 extender, for new 100-400 it depends on:
IQ, Price, Weight.

Nice small good lens :)
But I will stay with 11-22 IS

Now I'm in situation where I have good discount on 70D until the end of July. But I'm really curious about 7D II specs and price, I'm not sure if there is a good reason to wait...
I hope we will have some specs until the end of July.

I have used FD 50 1.4 on EOS, but it was with reworked mount from FD to EOS - no optical adapter, no infinity focus problem.

P.S. Canon Bulgaria gave us the best that they have for this pics - 1DX, 5D III, 70D; 300 2.8L IS II, 400 2.8L IS II, 500 4.0L IS II, 200-400 4.0L IS, extenders  8)

The better news from this one is that third party lens manufacturers are going to release lenses for M system!
I hope Sigma to join too :)

So we have enough dark zoom lenses - put small primes and interesting zooms on priority.

400$ for 55-200 6.3 kit telephoto zoom?

Are they out of their minds?

Could be a good compact travel telephoto, but I would not pay much for it.

Where are 135 2.8 and 85 2.0 and 50 1.4 for M? Come on Canon, we need some nice primes!
