EOS Bodies / Re: Ron Martinsen Blasts the 7DII in his review
« on: Today at 01:11:31 AM »
Who's Ron Martinsen?  :o

Wondered the same thing. For those interested, the following may answer some questions:

https://www.linkedin.com/in/ronmart

Wow, very telling. So much wrong both technically and photographically in the review so.... of course he is a chief technical programmer for MS and an invited speaker with big connections in the photo world.


At least he isn't afraid to speak his mind though.

That's a very poor review. I don't feel like typing out all the problems with it again. If you search on DPR you can find a good break down of that review (basically everyone agreed that it's off in many ways, Canon fanboys and not all agreed for once).

Check out photozone.de results! The new 100-400 II is killer! It actually handily beats the 70-300L and 70-200 2.8 IS II at 200mm!! And it's crazy good at 300mm too. And the 400mm is fine and big jump from the old version and, other than for edges, old slow prime!

For whatever reason, I find that photozone.de results have most often matched what I've personally seen.

As usual, PZ gets the numbers all wrong.


No, if anything, TDP gets it all wrong. Every Tamron they test looks like it was dropped. Their 70-300L does horribly compared to how mine did vs various 70-200 lenses and compared to what PZ and about 85% of blogs say. How come they have the 70-200 f/4 IS + 1.4x TC better than the bare 70-300L???

And how come TDP shows the 100-400 II + 1.4x TC III MUCH sharper than the 100-400 + 1.4x TC wide open and near wide open and yet the same or even blurrier without the TC???

How come for some lenses the results get blurry a couple steps down from wide open and then get sharper again and then get blurrier again?

If anyone thinks Canon wasn't going to one-up Nikon, Sony et al...they haven't been paying attention.  Market leaders like Canon don't jump at the first trendy innovation brought to the market (i.e. 4K on your wristwatch cam), market leaders got there by having proven, reliable, differentiated technology, and support for it and that takes time.  Sony's A7s is an EXTRAORDINARY camera - no doubt.  But those Canon pros that sold all their Canon gear to move to Sony on a whim this year will be regretting it - at least financially - when Canon introduces this or similar camera in early 2015.  Sony's camera division makes money, the rest of Sony does not.  The bankruptcy dangers for Sony are very real and have been for a few years....you don't read anything about Canon having financial issues though.  I wouldn't be surprised to see Sony sell off it's photo unit entirely to raise cash if they can't make the rest of their businesses profitable soon.

Market leaders do do that, they sit, milk, stagnate and over time get replaced by the next hungry, charging forward tech company.

It almost needs to be both semi-high fps (at the very least in cropped modes (sRAW or mRAW speed won't do it since those kill all the reach for sports and wildlife)) and high DR otherwise if it is very slow then it's not longer quite as great for sports and wildlife too...

Although I'm sure many of us consumers would want that, I doubt Canon will see it as a need.  I say 4 fps max, no crop mode.

I think that would be a dangerous game as I said though.

Once it has no crop mode (to provide reach with speed) and is a 4fps only camera it becomes much less general purpose and much more landscape oriented, at which point a less expensive Sony+adapter might seem more enticing for many. If the Sony couldn't take Canon lenses, they might manage to get away with it, but the Sony stuff can be adapted so....

Anyway, if it has a crop mode, which would cost zero in parts to implement and only the most utterly minimal in human programming resources (so only the worst of marketing droidism and Canon we didn't do it first so it can't be goodism, would deny it such a mode), and they let it hit 7fps in cropped mode than it suddenly becomes very exciting compared to the Sony stuff. You get even more MP, the same DR (I'm going the perhaps insane assumption that Canon won't release high MP FF unless they can match on DR, sadly I feel I will be disappointed though, but I will assume I won't here) and you get a built-in crop camera with tons of reach and speed. That looks way more enticing than the Sony stuff.

If it has slow fps at FF and no crop mode for speed and doesn't match DR and costs more.... then yikes.

Some say that 36MP is enough and that they don't need 50MP, if so that makes it a bit trickier for Canon.

It almost needs to be both semi-high fps (at the very least in cropped modes (sRAW or mRAW speed won't do it since those kill all the reach for sports and wildlife)) and high DR otherwise if it is very slow then it's not longer quite as great for sports and wildlife too in which case for those who could live with 36MP instead of 50MP the Sony stuff might look better since the price much be much lower and they take Canon lenses and yeah the Sony stink for that stuff but if the Canon has very slow fps then the 5D3 type advantages over the Sony stuff are much less anyway (of course the better AF still would help some, but maybe not as critically for as many as if the fps were also able to hit 6fps, at the least in an aps-c cropped mode).

Then again a cropped mode should be trivial to implement and driving a 20MP cropped mode at 6fps would be trivial since even the much older 5D3 already drives more data than that and already has a mirror box that fast. It just seems tricky because Canon tends to not agree that something they didn't do in the past (cropped modes vs sRAW/mRAW) could ever make sense in the future.

If it has Exmor DR, 50MP and hits at least 6-7fps in at least cropped modes and has 10bit 4k it could be an utter beast though. 4fps 50MP, 5fps aps-h, 7 fps aps-c would be quite reasonable at this point in the time to pull off even with single DIGIC (they could really make a mark if they went dual digic).

Some one earlier wrote:
No AA filter = not positive for anything but the company making the camera (AA filters are very expensive optical devices).  Removing it does not help image quality, and it does hurt image quality of still images.
[/quote]

Do you use cameras with and without the AA filters?  I shoot the D800, 5DIII, D800E, D810 and the D7100.  In ALL cases, for my most detailed landscape work at low ISO, the cameras without the AA filter produce superior IQ Images to ones that have the AA filter and I have the large prints (3 feet by 2 feet average size) to prove it.

I've seen aliasing and moire pop up in some natural world scenes taken with the D800E to a greater degree than I've seen with AA'd cameras (even then sometimes you can see a bit).

yes , and it is regarding  Canon sensor layout and read out, more Mp means also higher dynamic range due lower read out noise from the individual pixel, more Mp is a easy way to increase Canons dynamic range, but the analog signal path way can  never be as short as, for example in  the Exmor and it depends on the early AD conversion in Sony lay out

In other words, no.  There are many other factors you mention above.  Just increasing sensor resolution alone isn't going to absolutely increase DR.

Taking current type Canon tech going to more MP tends to very, very slowly lower SNR and very, very slowly increase DR. The gains in DR going from 23MP to 50MP won't be a whole lot and SNR loss won't be a whole lot. In more extremes like 8MP vs 250MP it can matter more.

There are many articles about the AA filter out there, so it's use is no mystery.  It is there to reduce moire, but it's drawbacks are less detail, sharpness and lower resolution.  That is why the newer high MP cameras have no filter.  Put the AA filter back on, and you lose the advantages of the higher MP count.  Pretty simple really.

no, almost everything you wrote there is incorrect

Admin - have you excluded the possibility that this is a 23-25 mp DPAF sensor?  I believe we were previously led to believe that Canon was launching a high MP APSC sensor (which later turned out to be a 40 million photosite 70D which takes 20 megapixel pictures).  Just checking to see if that's the same thing here.  If it's a 5D model, the line Canon is known for video, I could absolutely see this being the case.

No, it will be "pure" (no DPAF) high res sensor body. Possibly build around Sony sensor (not sure).
From technical point of view it would be better to put that sensor into mirrorless body, but I don't think they are going to do it.
Could you explain why the sensor would be better in a MILC, rather than a dSLR (from a technical point of view)?

1. No mirror = no vibrations = better use of high res.
2. CDAF for more precise autofocus

High res body surely won't be an action camera, so mirrorless would be just right ;)

just go to liveview mode

(and the mirroless a7r has more vibration than 5D3 does in liveview silent mode 2)

A Canon sensor with the same technology 7D Mark II, but "stretched" up to 50 megapixel, would get much better score when DXO down convert to 8 megapixel, and the theoretical DR would overcome any camera that Canon has released to date.

nope, that's not how DR from Canon sensors scales, it's about the same at any scale

More megapixels is only part of the problem.

Better megapixels is the more significant problem that Canon faces.

If it simple scales up any of its current APS-C sensors to full frame then it won't address the megapixel quality problem.


Yeah if it is just the 7D2 sensor x1.6x1.6 and 4fps and same old same old video, forget it for me.

It would have great reach, but so does the 7D2 for a lot less and with tons better fps and way less wasted space around the edges for wildlife. It wouldn't compete, in my mind, with D810/A7R for landscape since I'd rather 36MP and lots of DR than 50MP and same old same old. So it would be a high reach, high detail but sluggish sloth with old school low ISO DR. That might do it for a few, but for sure not me.

I'd sooner get a 7D2 even. (but would get a bunch of Sony stuff to add to my 5D3 (unless swapped that for a 7D2) or maybe just go Nikon out and out with a7sII added on or something)

I hope it's not just the 7D2 sensor in full frame. 20MP*1.6*1.6
Personally that would do nothing for me. No improved low ISO DR. The reach is the same as the 7D2 and the 7D2 would surely cost less and deliver far more fps. At 50MP it might not hit the critical 6fps of the 5D3. So it wouldn't improve DR, would have reach but no speed, all it would do it proved tons of MP, which is nice. But I'd rather have more fps and DR than just a ton of MP.

If it does 50MP at 6fps, has Exmor DR, then wow though.
And if it has good video too,10bits and real true not mushed up waxy 4k then wow .

One would hope it will have crop modes instead of the IMO largely useless sRAW,mRAW which aren't even really true RAW so then you could have 20MP APS-C and hopefully at least that could be drive at 6fp and for all those distant bird shots do you really want to have to deal with and store 30MP of useless borders when a crop mode could save you all of that mess?
