Patent: Tiny Canon 100-400mm lens and camera

Canon continues further development of its miniature lenses for what appears to be smartphone applications.
This is a patent (USPTO) for the Canon 100-400mm camera/lens that can fit in the palm of a child’s hand.
This patent explains more about the camera, along with lenses that will mount to it. In theory, Canon could develop a range of different focal lengths that will attach to the camera unit.
Could this be the birth of a tiny new camera and lens system? I don’t know, but it’s definitely an interesting concept that appears to be deep into development.

All of these thrushes have incredible songs. But I think this guy is my favourite.

I couldn't find a thread focusing specifically on the unique animals found in Australia so here we go. Wild or captive is fine(if captive it would be good to be aknowledged). I'll start with a couple taken recently at a sanctuary called 'Tasmanian devil Unzoo'. It has some animals that are retirees from the Devil breeding program(which is designed to build up a population free from the deadly facial tumor disease) and its philosophy is to have as little in the way of enclosures or barriers as possible. A great philosophy and a great place.
Canon RF 85 f1.2 L first impressions

I got the RF 85 f1.2 L two days ago, and have been trying it out on the streets.
I have compared it to the EF 85LII and the EF 85 f1.8. I don't post any comparison pictures here, but long story short, it is much better in every measurable way other than size and weight.
1. It is huge! It makes the EF 85 LII look quite small and cute. Fortunately, it doesn't feel too bad an unbalanced on the EOS R, but it feels more front heavy than the 85LII does on the 5DIV.
2. AF is fast and accurate. It isn't as fast from close to infinity as a 24-70 f2.8LII, but still very good. I'd say going from close focus to infinity and achieving focus takes less than a second. With shorter focus pulls it is much quicker.
3. It is super sharp from edge to edge wide open. Look at the brick wall picture that is attached. It is at least as sharp as the RF50L, probably sharper (if that is possible).
4. It has no chromatic aberrations. The picture from inside the train station, with the window posts, is a torture test. The Zeiss 100mm f2 macro planar shows chromatic aberration in this scene. The RF 85Lf1.2 has none, even at f1.2.
5. If it has any distortion, I am unable to see it. I refer to the brick wall picture, and the picture from inside the train station.
6. Bokeh is very pleasing. When I compared it to the EF85LII, I found the RF85L to have softer and smother bokeh at "normal" shooting distances, from close focus to maybe 4 meters away. When focusing at approximately 60 meters though (the scene from within the train station), the EF85LII has a noticeably smoother background - f2 was smoother than the RF at 1.2. (I haven't done any comparisons between the two between 4 and 60 meters focus distance.) Personally I would prioritize the lens that has the smoothest bokeh at shorter focusing distances (the RF).
7. It vignettes at f1.2, but its vignetting doesn't bother me. The vignette has a very smooth transition to it. You can judge for yourselves, especially from the brick wall picture.
The pictures are all shot handheld. The brick wall test is shot at 1/250 sec and could be affected by camera shake. The other images are shot with 1/800 sec and faster.

Canon patent shows new tilt mechanism and working process
- By keithcooper

A new patent shows a lens design with powered tilt and focus (along with sensors to feed back position info. Delve further and there are flowcharts showing how the tilted plane of focus can be matched to a subject surface.
Interesting info since I know from my teaching work that positioning the plane of focus along an arbitrary plane is something more photographers don't grasp with TS-E lenses the any other aspect.

New 70-200 lens

I just got myself a new 70-200 F4 IS II.
I've used the 2.8 versions, but found them to be too big and heavy to use all day, so I bought myself an F4.
As light and easy to use as my 24-105, and as I rarely need F2.8, I went for this.
Got it cheap too.
Here's a few shots I took yesterday. IT has great bokeh. Of course, I had to get some shots of my cats.
What else do you test out a lens with?
Taken with 5D3 and mostly wide open.
