1) Since when is the 5DS the first choice for wildlifers?! It was billed as a tripod/studio/landscape/product workhorse, not a higher ISO + higher FPS instrument. I appreciate the opportunity for added detail or the option to crop, but there is no free lunch with a 50 MP rig. Even with dual DIGIC, the throughput can only be so high.

I feel same as I said before for the D810 -- it was no wildlife camera. You might reel in great shots with it, but at 5 fps in FF, you will miss moments. But I'm seeing a trend here with both the D810 and D850 being referenced: it appears you value detail over FPS disproportionately to most wildlifers I've corresponded with. Most of them want detail of course, but value cleaner high ISO and higher FPS.

So your 'grass is greener' with the D850 comments make perfect sense for your needs. Thanks for clarifying.

There was a poll at Thom Hogan's blog regarding a new Nikon camera (before the D850 came out). How that transfers to Canon is an open question, but I could image the distribution is similar:
http://www.dslrbodies.com/newsviews/survey-says.html .

The percentage wanting a D5x-type body isn't that large (1.29%) compared to a D500-like body (16%). Canon certainly does similar polls and this will greatly influence the specs of the new body.

While the 9 pt AF isn't exactly top notch the sensor delivers just according to DxOmark especially in the DR territory and is between 80D and 5D mark iv in this discipline. While I do not believe that .2 or .4 matter / are exactly measurable with one body it shows that the possible IQ of the 200D / SL2 is up to current (Canon) standards. Nice to have that in a very affordable well designed package.

Coming from EOS M and 5D classic it is a 2 stop improvement which helps a lot - not on paper but for the results.

Click to expand...

Now I know that DxOMark ratings are bizarre - the 200D gets a better landscape rating than the 5DS or 5DS R? Higher than any other Canon bodies other than the 5D IV and 1DX III? Nothing against the 200D / SL2, but that seems pretty crazy.

DXO can confuse people who read their postings, and those who can understand what they are saying know its often a red herring.

Camera ISO settings are plenty accurate, no matter what brand. DXO is off into theory, and you have to read their fine print. A camera, even with manual settings can only set exposures to 1/3 stop, so adding in camera variation, a better than 1/2 stop accuracy is hopeful. Its the nature of the beast, nothing is perfectly accurate.

They are apparently unable to actually measure sensor full well electron count, but have devised a home brew method of attempting to measure it, and claim 1% accuracy. That's a pretty doubtful claim.

It has nothing to do with the camera giving a proper exposure, or at best its sort of related. Note that they never actually test a camera exposure, just a theoretical measurement that does not take into account any internal camera calibration of shutter speeds.

This caught my eye, I'm not nor ever will be a serious video or cinema photographer, but what is interesting is that DJI has expanded its photographic capabilities so quickly in the past 2 years. Buying a big chunk of Hasselblad may have allowed for technology expertise to start doing things they wanted.

We've all been waiting for the Chinese photography industry to take off and blow away the old high priced establishment. Its starting to look like DJI might be the current candidate to do it in the next five years.

They have not yet targeted conventional still or video cameras, but with the technology they have, its only packaging.

Me ol' da had something to say about wishing..."Wish in one hand, sh!t in the other, and see which fills up first."

I'd love to go and shoot this event! I was watching a special on the Weather Channel this morning about the Albuquerque Box. It is pretty interesting how the weather plays a role in the flight patterns. Its worth looking up if you are not familiar.

I would not get the old EF 24mm f/2.8, especially if it is used. Refurbished, possibly, but I still think you have better options.

If you are cost-constrained, get the pancake. It's sharp but not much else. Note that lens is focus by wire, so manual focusing is possible but not nearly the same as with a mechanical focus ring -- that may affect your macro aspirations with this.

If you are not terribly cost-constrained, 100% get the EF 24mm f/2.8 IS USM. It's a proper lens that can do much more than your other two options:

• Ring USM poops all over STM for focusing speed
• It's a proper lens feature-wise: solid hood and attachment mechanism, distance scale, standard front filter diameter, etc.
• IS is super useful
• Very well built. Other than the weather sealing difference, these lenses are 'sleeper L' lenses in terms of modern build quality. I honestly find the build quality on par with my ~ $1000 L lenses (not as nice as the pro f/2.8 zooms and f/1.4L primes, however)
• FTM mechanical focusing -- generally not a big need on a 24 prime, but if you want to dabble with tubes and macro, this lens would be better than the two you are considering.

instead of the current square matrix with twice as many green pixel sites as red and blue. This triangular matrix would allow many more effective pixels to fit into a given area and wouldn't require whatever algorithm is used to halve the green values. I assume though that there is some technical reason it can't be done like this as it seems so obvious.

just in regards to back lit subject situation:
I use GODOX X1T-C transmitter AF Assist Beam to aid camera AF abilities in back light situations. it may help quite a bit unless you shoot in very low ambient with strong back light beaming from behind the subject.

AbsN said:

After testing two copies of the Sigma Art it was clear the used lens was very soft from mid frame compared to the new one and the corners were nowhere near as good.

I'm aware there have been many reports of auto focus issues with this lens. After a very quick and rough calibration I got the lens focusing really well. However I've noticed there is one problem: it really struggles if there is any kind of back lighting. In fact it's as though it just can't focus with a bright light source behind the subject. If you switch to live view it will focus on a back lit subject perfectly. Anyone else experienced such issues? I am starting to seriously consider the Canon 35ii now!

I’ll second that. I use my Broncolor modelling light to help AF outside and it really makes a difference, and LV focus is another option, just wish they could make it continuous .

SecureGSM said:

A little experiment, should we?

See if you can manual focus while depressing the DoF preview button on your camera...
Let us know if you could

chrysoberyl said:

Just so I'm clear, 'Stopped down manual focusing in Live View will account for the change,' means that I can set the f/stop while in live view and I can manually focus at the set f/stop?

SecureGSM said:

I mentioned the caveat. What I didn't notice during this shoot was focus shift. As this lens is stopped down, the plane of sharp focus shifts farther away. Because Canon cameras focus with a wide open aperture, this change is not accounted for during either viewfinder or Live View-based focusing (AF or MF). Stopped down manual focusing in Live View will account for the change, but ... this is not how we typically focus...

This all feels related to Canon’s upcoming full frame mirrorless camera(s).

Click to expand...

Clearly the patent about automated AFMA is for a DSLR. The figures clearly show the mirror.

BTW, it's AFMA per AF point, i.e. you can have -5 for one focus point and -1 for another for instance. I haven't read all of it, but the menu screenshots went on showing a "near" and "far" position. So, it's still limited to 2 focal lengths for zoom lenses (unlike Sigma dock which allows to configure 4 distances). And no mention of different focus distances. But again this is based on pictures, the detailed text may say otherwise.

Too bad though, this is definitely something we wanted to have in the 5D4.

Thanks everyone. I appreciate. I had never even heard the term full time manual before. So thanks for the education. I had always just done that with this lens, as it never seemed like I was forcing it. So I figured it was okay.

Thanks again for the info!

Canon Rumors said:

For the second time in the last couple of months, we’re being told that a new DSLR series will be announced some time in 2018.
Neither source could name the series, only that it appeared as a “new DSLR series” in a presentation.
If we’re thinking out loud, I think these would be the obvious candidates.
EOS Cinema DSLR - A cinema DSLR camera to replace the discontinued EOS-1D C. This has been talked about numerous times over the years.
EOS-1D Xs - A high megapixel pro series body. Since the amalgamation of the 1D line back in 2009, we’ve always wondered if we’d get a camera like this to truly replace the EOS-1Ds Mark III.
EOS APS-C Cinema DSLR - A cheaper 4K cinema alternative that would “protect” the Cinema EOS lineup of cameras.
Hopefully this will bring a bit more information to the surface. For the moment, this is a [CR1] rumor, so please treat it as such.

Click to expand...

...and maybe a Full Frame Mirrorless.

Some think that the EOS numbering has recently become stable ad predictable even for the M series.

No complete overlap between DSLRs and Mirrorless, but it could sound like:
100D/200D in Europe (SL1/2 in other Countries) and EOS M100: basic and small models
6D and M6: enthusiast models
5D and M5: more advanced models
Therefore, I expect to see a M1 (full frame mirrorless) as ambitious as a 1D(x).
We'll see.

Click to expand...

Except that a M6 does not equal a 6D. An M5 does not equal a 5D.

bit less than 1.2 stops of DR difference at the base ISO. more like a 0.8 of a stop and only at ISO 65

High ISO performance of 5D IV is noticeably better though.
In addition, DPAF performance of the Canon in comparison to Nikon is simply "off the chart"
Aha!

Canon EOS 5D Mark IV Maximum PDR: 10.83 EV Low Light ISO: 5011 Low Light EV: 10.65
Nikon D850 Maximum PDR : 11.63 Low Light ISO: 4115 Low Light EV: 10.36

If DXO data is accepted:

• The D850 has more dynamic range (at base ISO) and greater color depth. The differences, in fairness, are not very large. For instance, 1.2 stops of base ISO DR will not let you leave the ND grads at home / abandon the practice of compositing multiple shots for tripod landscape work. Further, the gap between Canon and Nikon has been dramatically reduced here -- the D800/D800E/D810 models were a wowzer-like 2.5-3 stops better than the 5D3 on this front.
  
  
• Though the D850's high ISO score isn't quite up to the 5D4's, it's not far off. I haven't seen a 45 MP file downsampled to the 30 MP of the 5D4 for comparison yet -- it's possible at downsampled D850 file might be cleaner than a 5D4 file.

So it's a little better depending on how you look at it:

Detail: Considerably better
Base ISO DR: Slightly better
General DR away from Base ISO: Similar
High ISO noise: Slightly worse (45 MP) to perhaps equivalent (30 MP downsample)

But there's nothing in the sensor data that I've seen thus far that the D850 will be an overall better camera in real world use. The D850 sensor captures more detail and conditionally outperforms the 5D4 in a few areas, but that drives right past AF, handling, LiveView/video use (where DPAF is a nontrivial consideration), etc.

As I said before, the D850 (like the D500 before it) is a spec sheet juggernaut, but it needs to work well in real use and reviews are needed to get into that. That said, I have much more faith in Nikon than Sony to deliver the potential of that spec sheet.

Dude, those 0.8 is what makes your images stand out, it's a winning ticket to Pulitzer and every single photo contest, don't you know? All images taken with the cameras having less DR are shame of photography, and must be consigned to oblivion. I'm pretty sure DpR would approve this message.

Absolutely not. Any non-realtime OS is not a good fit for something that requires the immediacy of a camera in settings beyond simple snapshots.

This is quite intriguing, as is the G1X III. Putting the quite good (imo) new 24mp DPAF sensors in both cameras makes them both much improved from predecessor.

I was actually surprised to see how small the EOS M10 is, it's not that much bigger than the small M43 camera Panasonic GX850.

That being said, so far with the limited specs rumored, the G1X III is almost my dream travel/backup camera. Fixed 24-120 lens with APS-C sensor.

Click to expand...

The G1XIII looks like being a good camera for me - travel or otherwise when I don't want the full size gear. There is talk of the lens being 24-70, not 120 by the way, probably due to the physical demands of the aps sensor. As it's a fixed lens camera the lens must be stellar for me to buy one, but I think it will be it it follows the G1X tradition so far. I agree with Neuro that wider is required, but I just stitch. Not always satisfactory I know, but for me it works 95% of the time when I want ultra wide.

So the key is a first class lens. We know it already has the sensor.

According to DXO the D500 has a similar kind of base ISO DR to the A7R II

I don't have your particular lens. I have the Tamron 15-30. That South African desert could be twins with the entire state of Nevada where I live in the USA.

I completely understand what you are dealing with. A lens that wide really does flatten a landscape when the terrain is so wide open and it will make mountains look many miles away and make them look small. Since I live in the small desert town of Mesquite (yup, that town), I've put my Tamron away for now until I move to the Dallas / Fort Worth area of Texas in the spring. There just isn't a whole lot that I can do around here with that lens that I couldn't do better with a narrower field of view. I've tried and tried.

Here are some links for you, and there are many more places on the net with tips. Hope you have some luck!

I've bought 2 1DX MkII's, an 11-24, a 16-35 f4 IS and the 100mm L Macro via CPW, I won't buy anything Canon without emailing Gordon first to see whats what. Can't recommend CPW highly enough, I don't think any of my stuff came from Profeel though.

P.S. I lied, my 16-35 f4 IS came from Profeel, perfect experience and highly recommended.
