Really Really need some advice on 5D2 vs 6D

[Mustank]

i also daddy
i now use 40d + 17-55 + 70-200f4
my 40d abit dying liao
that time the shutter button nearly up lori, i use contact cleaner, 95% healed
now, coming back again....
may need new aps-c body soon

which apsc body is number 1 is sports auto focus?

i realise if i use polariser with the 70-200f4, auto focus is slower

i never use a 5D2 before but i have a 6D.
I would say the focus is slow on 6D too and i believe changing to 6D won't make much improvement or maybe none at all.

Thank you! hmm I don't think I won't be fast enough to use manual focusing having to manage my kid action and not to forget taking care of his safety all together..



Oh gosh, your comments are really spot on! You know exactly how I am feeling. Yes I am looking for the "Holy Grail" solution which kinda sounds like is there a 70D + 17-55mm solution in the FF?

Maybe I should be using 5D2 with 50 f1.4 as a better combination.

There is..but as u mentioned u are on budget so leave that aside.
but since your 70D + 17-55mm focus is fast enough,why don't u just use that?
Its not easy to tell from the photos what type of sensor u were using to shoot.
have u consider selling the 70d,17-55mm and 5d2 and get a 5D3?

Currently own 5D Mark II and 40D, before I purchase the 5D II, I did ask some professional photographers who currently using 5DIII, 5DII and 6D regarding AF and image quality. Since I mainly do landscape photographic, for ISO 100 no different between all three camera body, but AF speed, 6D somehow the performance is slowing than 5D II.

After using for 5DII for a few years, there are some way to slightly improve AF speed:

1. Use only the center AF point only. If you select all AF points or any point other the the center point, sometime it might result very slow AF speed. Please refer to manual pg 81 for more detail for selecting the AF point.

2. Enable the C.Fn III-7: Autofocus/Drive AF point area expansion. When you select AI Servo AF and the center AP point, the six Assist AF points (pg80) will also function. Seven AF points will track the subject. This is effective for subjects that move erratically, making it difficult for only the center AP point to track it. Manual page 199.

For fast AF focusing speed, the performance for 5D III, 70D and 7D will be a better camera body to work with.

Used to own 5dmk2 and 24-105mm lens, used it on my friend kids bday b4. It not easy to catch fast action so need some anticipation.
Now my main camera which is the old 7D, it fast enough for most action and gd enough for my use. 70d using same 19 point cross type (maybe improved?) so it should be gd enough for ur use for fast action.
And if u use live view, stm lenses focus faster on newer camera like 70d, 700d etc. Saw YouTube test b4 that stm lens focus slightly faster compare to usm on those camera even when during normal use (viewfinder).
But drawback is it not constant aperture for zoom lenses.

Yeah I used my friend's 18-135 STM before, AF really quite fast. Another drawback of STM lenses (apart from aperture - I think in future there will be constant aperture STM lenses) is that the lens will go into "idle" after a while and you need to switch on the camera meter (half press shutter) in order to get the AF back to where it was (otherwise the lens will be totally out of focus). That often slows you down and offsets the gains in AF speed, unfortunately. Or maybe it's just that I'm still not used to that.

i realise if i use polariser with the 70-200f4, auto focus is slower

Polariser cuts the amount of light entering the lens, so AF will be slower.

Anyway, sometimes slow AF speed can be due to user error. All AF systems need contrast to work. If you point the camera at something with low/no contrast, the camera cannot lock focus. For people, you generally want to focus on the eyes, and not some random patch of the face where there is little contrast (particularly if the subject has good complexion)

Bro I am sure you meant 6D's center point, not 60D

Thanks bro... I've edited to correct.

In full frame terms, a close equivalent to your current setup of 70D + 17-55 f/2.8, is the 6D + 24-70 f/2.8.

As someone has mentioned earlier, I don't think you'll notice any difference in your photos between the two systems. Unless you have the BBB bug, I would stick to the current system and save up over time for the 5D3 or its successor.

Personally, I have migrated from the crop sensor system to a full frame setup and I do appreciate the subtleties between the two systems but that is all there is... just a subtle difference. If your main genre of photography is capturing your children's youth (one of my favourite subject areas too), then I would stick to your current system and either save for the 5D3 or buy additional 'fast' lenses.

BTW: The 17-55 f/2.8 is a great lens and it used to be one of my favourites!

i also agree on 70D + 17-55 f/2.8, is the 6D + 24-70 f/2.8 cannot tell any different ..unless u shoot with a very high iso like 6400 then u can tell the different.

70D is among the fastest autofocus system in non 1 series body (phase detect on sensor ) second is 7D .

Hello everyone, so I gave my 5D2 one more chance during my weekend in a indoor playground. There are indoor lightings and natural sunlight coming from most angles. I would say it is bright but not exactly outdoor brightness.

I tried using 5D2 with my 50mm f1.4 and was on f2.8 or f2.... I still can't get the performance I was looking for. The improvement from 24-105 to 50mm wasn't that much but when I switched to my 70D and 17-55mm.... everything just worked and worked... video was also great. To be fair 5D2 technology is rather old so it is not fair to compare like that but I guess 70D is more suited to my application.

I kinda miss the FF colour and low noise when I need high ISO. I hope Canon is going to give me good news in September on the new 7D mkII or new 5D4 so I can grab 5D3 in BnS at a more affordable cost... ;p

Thank you everyone for your honest feedback and it really did helped me. CS has always been a wonderful community compared to the other forums where I guess I would have been flamed or given some 'just buy and buy' kind of feedback... hehe

To be honest, I'm really doubtful that Canon will bring in load of new and better AF ("groundbreaking") technology on the rumored 7D mk II as compared to 70D. If you will be making an upgrade, it will be really for other factors like shallower DOF and ISO noise performance.

*Discalimer...Neither did I owned nor used a 70D before. I've only been reading these from forums and review sites.*

 

[SilentSeth]

Knowing Canon.. I also doubt it :bsmilie:

Perhaps 7D mk2 will simply adopt 70D's AF with some "extras" (these extras might be additional AF points etc). Hopefully better ISO performance and higher dynamic range as well.

oh man, looks like if I really need to upgrade I am looking at 5D3....

 

[SkyStrike]

:bsmilie: most likely. But do keep in mind that lens still do play a part in the speed of acquiring focus. Even with superior AF module in the camera, you will need compatible (or "more" capable) lens to tap into the new AF module.


*** aiya, Just keep shooting with your 70D + 17-55 + ext flash lar :bsmilie: One of the most perfect setup liao

 

[Radiant]

5D3 is really a good all rounder. Fast focusing and yet FF quality images + low light. Never regret upgrading from 5D2. Everything just works on whatever lenses.

 

[voice123]

sell 70d 17-55 5dm2 u can fund 5dm3 le...but for me having 2 systm is better seeing tat 70d is pretty new

Autofocus speed is largely depend on lens than body.
Lens 65 : 35 Body
For me, I don't shoot sports. 6D is sufficient.
Why 6D not 5D mk2?
1) Lightweight
2) Try the both camera's shutter curtain. 5D mk2 "CLANK"! 6D "click". The sound of shutter curtain is softer on 6D.
3) 5D mk2 old Evaluative metering. 6D iFCL metering is alot improved.
4) DIGIC processor on 6D is same as 5D mk3! But cheaper
5) Built in wifi, backup to external HD instantly. No need to SD slots.

For faster autofocusing, try to look for Ultrasonic motors and larger aperture lenses.

Nope this helps.

 

[Turbonetics]

Autofocus speed is rather complicated topic.
it is really hard to say whether lens or camera body is more important or the bigger the aperture the faster the AF will be is not always true also.
I would say both lens and body are important for fast and accurate focus,if i had to choose either one,i would probably lean more towards camera body.

How to backup to external HDD instantly? I thought need EOS remote app and only can download jpg

 

[art2d3d]

Sorry. Wrong info. about backup images to External HD instantly.
