We kinda hope the 70D would have a new sensor - that 18M one is getting worn out now it's in so many current bodies.
If it does and the specs converg towards the 7D then that leaves less space for a 7Dmk2.
So my hope is for a 6D which is the low cost FF prosumer answer.
Canon 6D, 24-105, 50 F1.8 STM
Sigma 70 F2.8, 70-300.

Well... I like the idea for APS-H in body without grip, I don't like big and heavy 1D series.
But I think it will be limited or pricey, in other case who would buy 1D X if there is 7D II with the same AF system and good APS-H sensor for 2k $.

Howabout a 24mps APS-H, 10fps 5DIII sized camera for $4k?

The 70D would be the $2k variant

4k $ - No, Thanks I'm amateur and this is pricey for me.
If I liked 1D series I would rather buy some second hand 1d for less.

And if 70D is 2k $ I would stay with my 60D for a while.

It's not like a 7D successor is going to get the autofocus capability of the 1DX and it is the autofocus ability of a camera that makes or breaks it with respect to sports and to a lesser extent wildlife.



A straight lift od the 1D4 AF would be big improvement on the existing 7D AF - but (maybe) not as good as the 1DX AF

Who knows maybe we will see a ultra wide EF affordable lens with the 7D2 announcement.

You mean like the already rumored 14-24? As I said above, that has a curved front element and is not suitable for use with filters.

I believe Lee/Cokins will work OK? (but not on the 8-15)

Doesn't Canon want all of those people buying the 1DX instead?

Don't forget the price tag of 7D more than half comperring with 1DX . Don't mention the IQ of 1Dx, much better than any APS-H sensor Canon my put in 7D2

I believe the 7D2 will be 22mp with 45 AF points from 1D4. and the price tag around $2500

Agree on the 1DmkIV AF part. It would be at almost no additional cost to R&D development.

As for the Lee/Cokins, they only work with the X-Pro series. I used them for the Sigma 12-24, with a custom made adapter for my 5DmkII.  You need a filter circle of about 127mm to clear the 12mm on a FF.  Since the 8-15 has similar FOV, it should be similar too.

The 8-15 has no way to mount the filters. Also a 8mm I suspect light leakage woud be a problem. On a tripod the tripod legs are a problem @ 8mm

Looks like you guys haven't played around wide angles enough ...

For the Sigma 8-16, this is what you need as an adapter to use square filters:

For larger lenses like the Nikon 14-24mm, there is this :

Cokin filters require a screw in ring to mount the filter holder and do not work with lenses that have a curved surface the same as screw in circular polarisers don't work.

Lee may work.

PL is the one filter I dont use except for the screw on/drop in types. Filter holders come in all shapes and sizes.

I was referring to the filters not the holders - X pro cokins or  100x150 Lees

The 8-15 is so domed that the flat filter isn't big enough to stop reversed vignetting (ie more light from the side)

It is my experience that the PL on uwa dont work properly anyway (from ff with 17-40)

Thats why you need something like the LEE filter kit that has side covers.

My Sigma 12-24 needed a custom solution for the light leakage. And basically sorted out, it has no light leakage.
Mine's with a friend on vacation now, so can't really snap a shot of it to illustrate what I mean. 

But .. you can get away with it with a little gaffer tape at the sides of the filter clips if you use the generic Cokin adapters.

The 8-15 would be blinkered by the mount

Even the shallow hood gets into the picture

No it probably will not.

The 8-16 and 12-24 have almost identical FOV's. I can use the full range of my 12-24 on my 5DmkII, I don't see why you can't for the 8-16.

AND as I pointed out earlier, you just have to use the X-pro filters and compatible kits as only those are wide enough for the 12-24mm.   Anything smaller won't cut it. It needs at least a 127mm diameter filter.

Here you are then

First shows 8-15 and the height of the dome and how close the top ot the hood is in height . The filter would be about the same height

Second shows the image at 8mm, clearly show a lot of the inside of the hood - that is where the light would come from. Put a mount there and the visual image would be blinkered

I am guessing a 200mm square filter would be needed - perhaps off a MF

I have no need of a filter so haven't persued it any further

More megapixels for the 70D.... why do you need more megapixels on a prosumer camera? Its unlikely  enthusiasts are going about printing bigger than A3. Stop with the megapixels and put the R&D into better noise and DR not trying to cram more photosites on when its not needed.

Stone writes  APS-H is far better than APS-C . . .
That maybe, but the FF is far better than the APS-H.

And said before but . . .
Why should Canon produce a APS-H sensor?
The R&D department needs af larger budget and will there be sold enough APS-H cameras?
And the APS-H camera will canibalize from 1DX, which is not that expensive any more.
And the APS-H camera in the "old days" was made for getting more fps than the FF camera could achieve. Now you have 14 fps, the finest of ISO etc. So why bother about the APS-H.
And the IQ and DR of the FF and the APS-C talks for not making a APS-H sensor.
So sorry guys.

Ever so right.  :) 18MP is enoug for prosumers. Better ISO, IQ and DR is far more important.  8
