EOS-M / Re: Canon EF-M 55-200 f/4.5-6.3 IS STM Gets Official

YESSSS, finally a tele for the M! Great news.

But... is that a plastic lens mount I see on the NZ website?? Or just black metal?

Lenses / Re: What was your first L lens?
« on: June 06, 2014, 09:05:52 AM »
Like many, my first L-lens was the 70-200mm f/4.0 USM. Amazing quality and sharpness for the money. I bought it not very long after I got my first DSLR, a 500D. Paired nicely with the 17-55mm f/2.8 IS USM.

Next came the IS version when I upgraded to a 60D. I still use it today with my new 6D :-)

... unless you're shooting faster lenses than f2.8 because for these it's got only non-cross precision, alas, "best" is a term to be better avoided when comparing tech items that perform very differently in different situations.

Where does it say that? Seems to me that the center point is cross-type from f/1.0 to f/5.6.

From the 6D manual:

Maximum lens aperture: f/3.2 - f/5.6
Cross-type focusing (vertical and horizontal lines detected simultaneously) is possible with the center AF point. The other AF points are either vertical- or horizontal-line sensitive.

Maximum lens aperture: f/1.0 - f/2.8
Besides cross-type focusing (vertical and horizontal lines detected simultaneously), the center AF point can also perform high-precision, vertical-line sensitive AF. The other AF points are either vertical- or horizontal-line sensitive.

It's great to hear that your 6d is working fine, but imho unless your 6d has another sensor array this simply means you're lucky (or didn't look @100% crops) - with wider apertures, the 6d af is f2.8 non-cross and falls back to f5.6.

Seems to me the center-AF point is always cross-type as long as the max. aperture is wider than f/5.6.

From the 6D manual:

Maximum lens aperture: f/3.2 - f/5.6

Cross-type focusing (vertical and horizontal lines detected simultaneously) is possible with the center AF point. The other AF points are either vertical- or horizontal-line sensitive.

Yep, that's the same one. I got it for under 10 bucks.

E-bay, look for 'Canon EMF AF chip' or 'AF confirm chip' if you don't need the EXIF data.

Ok, thanks. I think i'll check it at the store with another one to see how that one feels.

Just finished chipping my 14mm with a Canon EMF AF chip :)

I had to make a spacer to get the chip's contacts to the correct height, but after that installation and configuration was very easy.

Works like a charm! Very handy to have aperture and focal length data in EXIF. AF confirm and AF adjust also works, but because the DOF is so large there is quite a lot of margin. Live-view x10 works better :)

I find the focus ring a but spongy, there seems to be a bit of a dead area before it catches and changes focus, is that normal?

The new one has the 'UMC' coating for better flare reduction.

I got it as well, just a few weeks ago. Thanks for the review, it helped me decide between this and the Tokina 16-28 f/2.8 which is twice the price here in The Netherlands...

I have the Samyang version. The ultra-wide angle opened up a whole new view on photography for me :-)

Here are two shots from the beach.

EOS-M / Re: The rumored tele lens for the M
« on: September 23, 2013, 08:07:12 AM »
I would love to see an EF-M 55-200, even a 70-200 with variable aperture would be fine. I use my M mainly when I don't want to carry the bulk of my 6D and want to be less obtrusive. In such cases I don't mind the lower image quality and the fact that it doesn't fit my pocket.

I got my EF/EF-M adapter off e-bay for around 35 bucks. It's a Meike/Fotga with a (sturdy) plastic body and metal mounts. It works great.

EOS-M / Re: EOS-M firmware update 2.0.2 available
« on: June 27, 2013, 08:08:00 AM »
I can't detect any difference in AF speed between single and multi-zone. They are both evenly snappy, it's difficult to estimate the speed, but I guess it takes about half a second for the camera to obtain focus. This is with the 18-55 lens.

The lens is dead-quiet, I notice no clicking or anything before or after the update. Does the clicking also occur when you disable IS? It could be the stabilizer switching on.

This is a great little camera, I especially like the movie mode with it's AF and it is now even faster. I'll be using it a lot in the future, stalking my 3 year old with it :-)

EOS-M / Re: EOS-M Firmware Update is on the Canon USA Website

One little quirk I noticed is when I just updated the firmware, the 18-55 lens would not work. I looked around in the custom-menu and saw I had the AF-assist light disabled. I enabled it and the 18-55 came back to life. I guess the camera needs a reset to the default settings after the update.

Other than this, no complaints yet!

Already updated my M this morning :-)

AF is indeed a great deal faster! Also in movie mode, perfect!

I tried my Sigma 30/1.4 with the lens-adapter, this also works a lot quicker.

Me happy :D
