New Canon full frame?

Well I found this an interesting read. Lots of stuff I wasn't aware of especially the AA filter on the 7D. I'm still in limbo, unsure what direction to go next. Swap brand or just keep on waiting to see if this cheaper FF comes out or a new top line crop.

I either sell my 70-200 2.8 and 17-55 2.8 and go Nikon with a D700
Sell my 17-55 2.8 and get this cheaper FF if it comes.
Get what ever new crop comes and hope it has a non plastic body and decent weather sealing.

The wait on Canon is bugging me, I want to make a decision on the speedlites but can't until I can make my mind up on route to take :D

It's a difficult one. I view the whole thing like graphics cards. Some years one supplier will be on top and it will to and fro. It's probably unhealthy for everyone if one company dominates. I wouldn't part with my Canon EF 85mm f1.2L II so I'm sticking with them. The 5D range aren't exactly bad cameras :) As for the crop cameras you should research whether you want a full frame or would rather have the features a crop sensor will give you.

There's loads of options on the Canon menus. I'm not sure if they will completely eliminate it. There's also the Canon DPP software which is very good with adjusting RAW files. Ideally you would hope high end cameras like the 7D would give better results.

From this it seems the AA filter can be removed, if that is the case then why is there not an after market AA filter replacement ! ?

Thanks, no was not aware of that. I was more aware of a full frame coming out soon that is not really made of metal but more like a rebel type construction (which I will not buy no matter how good it is the rebel line are very cheaply made in my opinion).


I hope the 70D is not this camera they speak off and is as fast or faster than a 7D and has better image quality.


Just going to do some google-fu and see what the rumours are for the 70D and do you know of a maybe release date for it yet ?

I'd check Canon Rumors. Photokina is between 18-23 September 2012 which is only seven weeks away. Definitely on the cards is a higher megapixel crop sensor camera and hopefully a reasonably priced full frame (anything less than the current Mark III sensor won't be acceptable for me otherwise a 5D Mark II will be the sensible option.) All will be revealed approaching this date. Whatever you do don't splash out on a new 7D just now. Whether it's the 70D or the 7D Mark II either one will be significantly better than the current 7D.

So there is no way via soft ware of turning the AA down if it is a physical hard ware issue ! ?

It is a physical piece of hardware, you can pay companies to remove the AA filter (as you can the IR filter). Often done by pro landscape photographers if they are not using medium format cameras (medium format cameras don't have AA filters)

People that want the AA filter removed know what the AA filter does and what the side effects of removing the AA filter are. If you want the AA filter removed you care about sharpness, resolution and micro-contrast and you know the side effect is potentially moire artifacts in artificial repeating textures.
If you want the AA filter removed it is unlikely you want a weaker filter put back in its place.
 
Depends, but if you don't want to use a soft lens, the other option is to increase the sensor resolution.

a) No need for AA filter if sensor out resolves lens (lens now becomes AA filter).
b) Only the extreme minutest repeating details will risk any moire.

from what I have read on the AA filter issue it depends what lens you use !

Not really, it is independent of the lens, yes if a lens is soft then you wont see the softness due to the AA filter but that is not very interesting. If you buy a sharp lens and loosing too much detail from an overly strong AA filter then the system is not performing optimally.

Awesome! Why did Canon put it there in the first place is my question?

To prevent moire and some issues due to specular highlights.

The real question is why did Canon use such a strong A filter on the 7D when other cameras using a similar canon sensor have a weaker filter and competitors feel that even weaker AA filters are sufficient.

That's the question !!!

Perhaps our engineers can tell us ;)

Its not an engineering question (the existence of weaker AA filter on the same and similar sensors proves that is was not a technical reason, beyond incompetence), more likely Canon product placement techniques to maximise their 1DMKIV sales

You are guessing?

There must be a reason, we, as outsiders can only guess.

No, we can do much more than guessing because physical and undeniable evidence exists that a weaker AA filter is sufficient for identical sensors and other sensor with similar pixel pitches.
 
Is this 7D AA filter nonsense still going on?

I've taken some fantastic pictures with the camera, as have many others and never found it to be an issue.
