I may get an excellent one-off offer for a 5DSR next week for a little more than the 5DS. So if I get one of these its going to be the 5DSR only because I got lucky and expect it will be a better sell one day.

Just got a mail offering me a 5DRS just shy of 3.300$ :o

Too tempting to pass - even if the 5DIV may be around the corner.

Lets see if I can post something later this week. 8)
Congrats on your purchase. I can tell your excitement. LOL

Haze in the Air

I'm back after spending 5 days at a convention in Spokane. As many of you know, we are having some extreme wildfire problems with over 2100 square miles of Wildfires.

From the 15th floor of my hotel, I have a three photos to show the difference a day makes. All of the photos have haze, but the second one was taken on a very bad day when the smoke was very bad.


Day 2

Day 3

The next day, after a wind blew the smoke towards Seattle and Portland, Oregon. (Smoke is back again now)

Canon 400mm or 100-400 for airshow?

Saw it on the News Martyn. Horrible crash and terrible casualty list.
As you say our sympathies must go to the families who have lost their loved ones - sorry you had to witness it.

Watching the crash happen through a telephoto lens was truly awful. In the first hour or so after the crash many adults were in tears and most were walking around in stunned silence. News broke that the pilot survived then stories followed about injuries on the A27. I couldn't believe that the pilot attempted at loop at such low altitude. The programme listed another pilot for the Hunter display instead of Andy Hill.

What to add to 7D and 70D

trulandphoto said:
OK, never mind. I'm picking up a local 5D Mark III from a local Craigs List seller instead.

Sort of a perfect answer actually, but I'll probably have to sell the 70D and/or the EF-S 10-22 to make up the difference.
Better decision, you won't regret that. I personally believe that the 5D3 is an excellent all-around camera and your 24-70L will finally shine.

Unlimited DR Camera invented by students at MIT...

Camera manufacturers have been researching ways to control each pixel individually, and adjusting gain to keep them from blowing out. So far, its not been practical to produce.

This definitely seems more practical. The University would likely want to license any patent they may receive to any and all willing to pay. Usually, they setup a company that is owned by the University to do this. A number of circuitry patents with designs for actually implementing the basic idea will differentiate products in the market place.

Look for something practical in 9-15 years.

5DS R review by Ming Thein

I think I've read just about every review there is on the 5DS R before I bought it, and I've had it now for two months and this is the first review I've read since I purchased it.

I absolutely agree 100% with his take on it, he provides a very reasoned and accurate take on the camera. Its a more demanding camera than the 5D3 or my old 5D2, but despite its faults I already love it.

Does this kind of AF patent already exist to improve DSLR phase detect?

Hi,

The A7RII is getting a lot of attention, especially as regards its AF ability. A lot has been said about DSLR phase detect's "moderate" ability to AF on a wide-aperture primes and AF micro-adjustments.

So, I was wondering if a patent such as the following was already reported here or elsewhere: the idea is to primary use the usual dedicated phase detect of the DSLR. Then, when mirror raises a second unit, on-sensor phase detect (Dual Pixel AF for Canon), corrects the slight inaccuracy by asserting good AF rather than predicting it just before taking the shot.

Given the fact that even if the external AF module is not accurate, it is not completely off even at f/1.4. That means the correction to be done by the on-sensor phase AF would rather be minimal, hence meaning NOT THAT MUCH time consuming.

The external AF and on-sensor AF would share the same AF points. So when the mirror raises, the on-sensor AF knows which was the selected AF point and therefore knows where the "correction" has to apply.

BTW, some DSLR already proposes a delay when the mirror raises to wait for mirror vibrations to dampen. So let's use this "idle" time to do what's described above.

The only "risk" would be that the viewfinder remains dark a bit longer. But aren't we already used to it when exposure is slower than say 1/60?

It will also correct from brand to brand variations (like Sigma not focusing as good as Canon lenses on an EOS body)

This would make wonders within the Canon AF dedicated menu where you could set a priority with a slider to the importance you allow to the "correction": from quickest (on-sensor AF deactivated) to not fire the shot until the on-sensor has 100% asserted the accuracy.

What do you think? Any reports of this?

If it doesn't exist yet, my idea first :D

Which Combination?

johnf3f said:
Just me but I would be more tempted by either a Canon 600 Mk2 or 800 F5.6 L IS and a Canon 300 F2.8 (any version) attached to a pair of 1DX cameras.
Note I am biased because I use a 1DX and the Canon 300 F2.8 and 800 F5.6 lenses!

The camera question is easy - good though the 7D2 is (I was quite impressed) the 1DX is simply better.
I cannot speak for the 100-400 Mk2 as I have never used one! I had the Mk1 for about 6 years and rarely used it at less than 400mm so the 400 F5.6 would have been a better option.
Whichever way you decide to go 2 x 1DX cameras is a significantly better option then any of the alternatives IMO.

300 f2.8i w 600 f4 is simply too much to travel with. I could travel with 600 and 200-400. Done that once but not likely again.

Ideally I would like to have 1Dx SS (small sensor). 1Dx with APS sensory.

Review: Samyang 135mm f/2 ED UMC

TWI by Dustin Abbott said:
Hjalmarg1 said:
Amazing results from Samyang, I have been tempted to get the Canon 135L but the lack of IS has stopped me to do so. Now I own the 70-200mm f2.8L IS II and I am very happy with my decision, even though if doesn't offer the same bokeh quality.

I know. I have the Tamron 70-200 VC (which actually has significant nicer bokeh than the Canon). Despite the slightly better IQ from the 135L I rarely use it. The amazing stabilization on the zoom and almost as good image quality means that I get more consistent results from it along with the versatility of a zoom. I'm actually considering selling my 135L despite its optical excellence.

I bought a Samyang/Rokinon a few weeks ago and yes, it's every bit as wonderful as Dustin says - better than the 135 L and, when attached to a mirrorless camera, more accurate focusing too (though I don't photograph fast-moving things where AF has an obvious advantage); the short mfd is appealing too. Add the image stabilization of Sony a7rII (and a7II too, presumably) and the results can be pretty stunning (I've not done any extreme tests, but I get perfectly sharp shots at the Sony default of 1/60, whereas I wanted at least 1/320 on the a7r). I would also note that my copy doesn't have the focus ring problem that Dustin's does/did.

DXO likes a Canon-made lens for the first time -- mass riots ensue

ahsanford said:
A 22 score all but certainly means that they are still not ready to release the data* for a 50MP test camera.

Fixed that for you ;D

DxO Optics Pro has had that lens and body combo profiled for some time, bottom of this link
http://www.dxo.com/us/photography/photo-software/dxo-opticspro/supported-cameras
They clearly have the data and are choosing not to publish.
On the + side they have published for my old 500D pheew what a relief ::)

How to view ALL Unread posts rather than just the ones since last visit

I own another forum and a very useful link is to view all unread topics rather than just the new posts since the last visit. For example, there might be something interesting going on that I did not get a chance to read, but as I return to the site it is now not visible since nobody responded since I left.

this is a link that will show ALL unread topics regardless of the last login (viewing) time:

Hummingbird in infrared

An option for those who may want a "full-spectrum" camera would be the Astronomik clip-in filter system:
http://www.astronomik.com/en/clip-filter-system.html I would think that one could order up custom filters, if needed.
There is plenty of info out there on conversions for UV photography. Scientific photographers often use UV.
Flowers often look different under UV, and this matters because many insects see into UV spectrum. Lenses that work for visible light may or may not be good for UV or for IR. "Process lenses" are terrific, apparently, because UV is/was used in photolithography and other reproductive processes.

Good 5dsr Review

dcm said:
Don't miss his follow up post where he discusses why he said goodbye to the 5DsR. It is equally insightful.

http://blog.mingthein.com/2015/08/19/long-term-canon-5dsr/
I think it's a fair assessment.

I like how he highlights that this is for his specific requirements and that Canon has not done quite enough (yet) to get full buy-in from someone in his shoes (someone already invested in high-resolution equipment)

p.s. I think it's really difficult to adjust to the dials of the two systems unless you get into them early on. Those dial placements get so ingrained in muscle memory that you can easily become frustrated if you start missing/messing-up shots. As I'm a very impatient person, I tend to struggle with this issue myself. I tried shooting with an older Nikon for a couple of weeks with and it never quite felt right. Anyway I was at the point of moving into full frame so I went 6D (and eventually 5D-III) instead of D600 and (eventually D810).

Canon 5Ds-r Martin Parr / Magnum - Just use it on Program Mode !

Hector1970 said:
At least we've introduced Martin Parr to a much wider audience.
Photographic Art is like soccer everyone has their opinions as to who is the best and who is rubbish.
Those who divide opinion are often the most interesting.
Martin Parr has really made it when he has his own thread on Canon Rumors.

TN, KR, and DXO have many threads here, so its definitely not a good thing ;)

The danger of high resolution and sharpness

QUOTE: "So the question is; Are we losing track of why we are doing this, in all this technical progression? Are we losing our ability to see a good picture in our strive for technical perfection?"

For the guys that began a career in film/slides, I'd say the answer to that question frequently, even almost absolutely is YES!

For the guys that began a career in Digital, not so sure - too many digital variables available on any shot.

For those that get lost in the 'digital perfection' it depends more on why you shoot the image, but to me it's the shot, the light, the composition, but most often the subject itself. I've seen - and also shot - some images that are technically 'less perfect' but are still top favorites. I'm also thinking the 'memories' a shot brings out have a lot to do with how one perceives its 'value' as well.

Not such an easy question to answer as it first appears.
