Lenses / Re: Upgrade or not the 24-70 f/2.8, a thousand dollar question.

You can sell the existing version I and get the new version II which is fantastic (I do have it...).

They can:

1. Improve hardware by changing their production line to make sensors that compete with SONY. OK this is EXPENSIVE but I guess it will put Canon to top again (and in that way pay itself in the long run).
2. Improve hardware by implementing their patent with dual amplification channels ( Dual-Scale Column-Parallel ADC Patent I think).
3. Improve software by implementing everything ML has done up to now.

If that is the case why SONY made a7S? They could stick to a7 and even more to a7R and that's it!


The A7s has more advanced in-camera noise reduction. Exmor is a good sensor, but it wasn't good enough to produce ISO 400k with the low noise levels that the A7s has. The Bionz X DSP is responsible for reducing the noise in each pixel as they are read out. Not much different than what Canon is doing now with DIGIC 6 in the 7D II. If it were not for the more advanced in-camera NR, I would agree...the A7r when downsampled to 12mp would have probably looked very similar to the A7s, primary difference being the downsampled A7r image would be sharper.
So in A7s they... "cook" the raw files?  :o


They do, just as much as Canon "cooks" the RAW files in the 7D II with DIGIC 6. ;P Everyone's cooking pixels today, it's all the rage.
In that case they should be able to "cook"  ;D the A7II files even better since the later camera is newer...

Unfortunately, it seems these days that for every new camera released on the market you have to give it at least 6 months before it moves from beta version to a complete product, with us customers being the beta testers.
This is true... The only positive in this is IF price comes a little down in the meantime...

Perhaps a 5D-s to prevent confused naming? Or will they just name it the mark IV and leave it as the successor of the 5d3?
Hmm I hope that the high mp camera and 5DMkIV will be different ones...

P.S Otherwise allow me to suggest 5Ds as Canon's answer to Sony's A7s (at... 12Mpixel ofcourse  ;D ;D ;D ;D ;D ;D ;D)

I don't personally feel 50mp belongs on a 35mm sensor.
Then again I'm sure someone said the same thing about 21mp in the years gone by.

Anyone tried the Pentax 645z yet? I've one here on loan and it's lovely.

+1
If I was a pro and actually needed high mp for my business, that's exactly what I'd be doing not waiting for a 3d or whatever it will be called. I trust Canon to keep the 5div to around 24mp.
I would like that but trust is a strong word! I just hope so!

Is there anyone willing to provide some mathematics as to why averaging let's say smaller pixels together with a S/N of 50 is better than less pixels (but bigger) with a S/N of 100?

For instance, there will be roughly 4 pixels on this camera's sensor for everyone one pixel on the 1Dx.  So, you could average 3 or 4 pixels together when downsampling vs. a single pixel on the 1Dx's sensor.

Thanks.
Quite a reasonable request  8)

Lenses / Re: What is your favorite lens/camera combo in your camerabag?

It depends on the situation. I will discard cases where I get a backpack that can contain 1 or 2 bodies with several lenses and I will focus (pan intended 8) ) on my small (and now discontinued) Think Tank Urban disguise 30.

Day Shooting with portrait potential: 5D3 + 24-70 2.8II   plus 85 1.2LII

Day/Night Shooting (only for portraits): 5D3 +  85 1.2LII (to make it lighter)

Day Shooting general purpose/travel: 5D3 + 24-70 2.8II L  plus 70-200 4 L IS (it is difficult and not practical to put a 2.8 zoom instead, plus it will make the bag very heavy hence the f/4 version). In practice a small 3rd lens can fit. If astrophotograpy is possible I will add a 14mm 2.8LII. 

Night Shooting (portraits, surroundings): 5D3 with 35mm 1.4L  plus 85 1.2LII

Museums: 5D3 +  16-35 4L IS plus 100mm 2.8L Macro

This bag is both small and discrete. You can go in several places carrying it.

I think the retrospective 20 is needed for 70-200 2.8

I haven't watched any of his videos and now that I read this thread I do not think I will in the future!

It's no waste, particularly if you might get a FF body down the road.  Glass lasts a long time, bodies change faster.  I never used the kit lens on my T2i or purchased any EF-S lenses for it.  I purchased L glass to go with it and and kept adding to the collection.  The 24-105L was my first L and it got a lot of use.  Three years later I purchased a 6D.  Some lenses that are soft around the edge might even benefit from a crop sensor ;-)

I later decided to go the M route for my crop sensor and added some EF-M lenses for it.  I occasionally mount some L glass on it.
+1 Exactly! I think FF L lenses is the obvious way to go if someone intends to upgrade to FF.

The only thing someone with APS-C camera may have to get in EF-S is 10-22 or 10-18.

« on: December 23, 2014, 09:42:41 AM »
I could think of a 22 MP 5DIV with 3200ish ISO 6400 and 12800ish ISO 25600, this would make some very usable ISO 51200. But I also know, this might remain wishful thinking.
It's a reasonable wish (if they update their manufacturing process...)
I wish it too  :)   (or at least for 5DMkV  ;D )
