Well said. No need to add more.

FWIW, I got a Kenko 1.4x Pro 300 DGX recently, to test it with my 70-200L 4.0 IS. I was wondering if a little more reach could stop me from buying the 70-300L in the future...

Turns out the Kenko is holding up quite well. AF is quick and without trouble on my 6D. There is some loss of contrast and sharpness & detail, which is predictable, but it's very acceptable. So I did a little comparison between a 1.4x @ 200mm shot, and a 200mm shot cropped to the same FOV, and upscaled to the original resolution.

Outcome is that the cropped & upscaled shot is looking better (sharper, better detail) than the one with the 1.4x...
So this teleconverter is going to be up for sale again!

Thanks for reminding me, I almost forgot!

A bit is a bit, right?

Canon General / Re: What do you Cheap Out On?

Bummer on the AC...

I went cheapo on:

- batteries, bought some chipped chinese clones and they work perfectly
- battery grip, I don't need the weather sealing, got the Meike grip. Works great!
- IR remote
- center-pinch lens caps
- lens hoods

Main reason for getting the cheapo stuff: I think Canon accessories are way overpriced.

Third Party Manufacturers / Re: DXO uh-oh?
« on: July 25, 2014, 06:54:35 AM »

Read the quote on DxO's web page:

"Here is a sample of some of our clients."

It doesn't say that those listed are DxO's only customers. It also doesn't say those listed are the top ten DSC manufacturers. It just says that they are *some* of DxO's customers. So Canon could well be a customer of DxO and if they were, then the statement on DxO's webpage is still true.

This is sooo sad...

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.

Maximum lens aperture: f/1.0 - f/2.8

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.
