can 70d do dpaf in crop mode?

[mlrocks]

thinking to get a 70d for its dpaf.
if it is working in crop mode, maybe 3k can be continuous due to its 75-80 mb/s recording speed.
seems dpaf works in uncropped mode, but not sure if dpaf works in cropped mode.
3k 1x1 10 bit raw with dpaf for a super 16mm sensor size is sweet.
hope 1x3 modes work on 70d in the future.
ml really rocks.

The answer is, sadly, no.

thanks a lot for the info. guess i have to wait for another several years.

Unfortunately, until a 70D-owning (or sufficiently interested to buy one) dev comes along, or some of the active devs gets their hands on a body, waiting won't change anything. That is, if changing DPAF behaviour when cropped is even possible...

[mlrocks]

if no dpaf in crop mode, can 70d do 3k 1x1 manual focus mode? 70d has 80 mb/s writing speed in video mode, almost reaching 7d, with a swivel lcd and better heat sink.

[elenhil]

Sure. As far as I know, you can focus manually whenever you like (provided your lens supports it), it does not matter if it's with ML running or without it.

[elenhil]

But keep in mind that 70D will likely always lag behind other Digic 5 cameras in terms of ML development precisely because of it's unique DPAF. It might even end up abandoned altogether if the devs get more excited about cracking DIGIC 6 and newer cameras instead.

Not sure what you mean with 3k, but with 14-bit lossless and 2.39:1 (as well as SD overclock @240MHz and Global Draw = off) I can go as high as 2560x1072, not higher. Actually, not always continuous rec. even with this setting, so maybe one should consider 2240x938.

2560x1072 is some 2.1x crop to add on top of a native 1.6x APS-C crop... wonder what focal lens one should use in most situations With 2240x938 you go to 2.4x to be added on top of 1.6x, for a whopping 3.9x crop factor relative to FF

Never understood exactly how these modes are usable in real situations. Maybe for airplane spotting?

Btw I'm unable to make the cropped frame centered on the sensor -- it is slightly on the right or on the left.

Also, fps is locked @30/1.001, seems impossible to lower it.

But not a 70D expert here... pretty sure ArcziPL knows much better.

this is not as good as 700d/650d/eosm/100d.

You definitely CAN achieve 2560х1313 at 11-bit lossless (I have, and it was continuous for 15 minutes), but it takes a scene that is not very busy (well, it works for a pond with water ripples, for example - just not some panning shot).

[elenhil]

One more thing to keep your expectations low: if you're looking forward to shutter wear-free FRSP timelapses, the thing is only sort of half working as intended. I ended up getting a separate 60D body just for that (but then again, has found that the AETTR wasn't really working for FRSP).

Indeed. That's why I got a 5D3 after trying ML on 70D.
