D Cox: Nice one. Congratulations.

2017 was the year I too finally got good shots of soap bubbles, after decades of trying. Interesting to see that your settings are the same as mine.

The same motive, the same settings :-)

Dutch Newchurch: The challenge host cannot vote, but you have earned a ‘Commended by the Host’ - with full bragging rights - for this colourful shot.
Congratulations too, on a well-deserved first place.

Thank you very much.

ozturert: Bokeh CA looks minimal and sharpness is good. Easy to recommend.
But hey, this is Canon so I should say "Canon sells us old tech!" :)

Here is an example of "minimal" bokeh CA:

monky: Maybe I'm spoiled by the BRO technology in the 35/1.4 II (which I know this lens lacks), but some of the samples here slightly disappoint me. Specifically, see image 26. Even at f/2, and even viewed at reasonable magnification, the axial CA (or "bokeh CA" as some call it) is visible enough to be distracting. That's practically a worst case scenario for that particular issue, but I was still hoping for better performance in that area, especially since that's an aspect where the f/1.2 II struggles.

I have the f/1.2 II, and was looking forward to this lens mainly for improved (and internally-focusing) AF. I was hoping for markedly increased image quality as a bonus... but perhaps I was being a little too optimistic. First-world problems, though...

I was surprised as well. Here is an example taken two weeks ago at Canon promotion event:
I've noticed also some problems nailing the eye in focus with 5D Mk IV, but thought it was my fault. Now not so sure...

Leonp: What are these lumps in the front? For the rest I see one and a half bush in the middle and some bushes further back. What seems to be the horizon is not horizontal nor is it visibly why it isn't.
I can't see the crispyness in the frost. Maybe it's because I can't look at the original 24MP pic, but I just don't see it.
There is a moon in the image but no stars and no interesting clouds.
There is no color scheme that enhances depth ore makes anything interesting.
there's no main or secondairy subject. But there's a very strong color cast.
I'm going to check my rejected photo's again....

To Leonp> Please do. And please don't forget to post it here for comparison.

I am quite surprised by the white contours around the edges.

I can't see the Pentax Program A.

I wonder why in EXIF data the aperture f/1.4 is declared when the lens is f/4.

In reply to:

vadims: I think it's about time for ISO to introduce another, logarithmic scale for measuring sensor sensitivity. The fact that the numbers look crazy does not mean that the sensitivity per se is "crazy" -- it's still far cry from the capabilities of the human eye.

BTW, "who needs more than ISO 6,400" sounds to me suspiciously similar to "640 kilobytes should be enough for everyone".

Just to remind that "kilo" shoud be wtitten with no capital.

On article Canon announces 16-35mm F4L and 10-18mm F4.5-5.6 lenses (368 comments in total)
In reply to:

DimensionSeven: I wonder whether the 16-35f/4 IS will be good for infrared.
The 17-40 is, but it lacks sharpness in visible light, esp. in the corners. The 16-35 f/2.8 is a better performer in visible light but has a nasty hotspot in infrared.

So do I. This prevents me at a moment to sell the 17-40L and order new 16-35 f/4L IS. BTW, have you any exerience in IR photography with 24-70 f/2.8L II?

Tiny issue? I am already sick and tired of manufacturers putting their bug products on the market just in order to overtake the competition. The customers are then very often persuated by service that it is not an "issue", but "property" of the product. I had similar experience with TV, mobile phone, lens. What kind of strange world do we live in?

On photo Fragile beauty in the Bubbles challenge (6 comments in total)

There is not too much to explain :-) I used black background and remotely triggered flash. The particular bubbles had different distance from camera, that is why some of them were pin sharp and others - out of focus.

Great shot! Having known the sculpture existed, I would have visited this place during my July stay in Singapore :-) BTW, I was deeply impressed by this city.
