Why do you stick to Sony DSLR?


and the next question would be:

on what basis do you make this claim. for your claim to be substantiated, it would have to have some form of comparison and tests have to be done.

Test with front and back motion tracking, C & N Best AF system don't make perfect on that as well, but much better than what sony have now, the what i'm waiting for.
 

Did u use the same comparable lens or not??
 

guys, lets not feed the troll :)

obviously some people just like make statements, but when u ask for proofs, he wont be able to show any to substain his claims.

so many 'pros' around making so many 'pro' statements, muz be too free. Go and practise somemore, dun blame it on the camera.

Of course not, i'm not reviewer. I'm not so rich to own both system and same third party lens for compare purpose.

Yeah, should stop here, i only need the camera to convince myself to purchase it not everyone else. Good or not test out yourself rather saying here, i'm not professional to proof anything.

Not sure you are pointing to who, but i never blame the camera, i just feel, if C & N can do it, same for sony.
 

For non Alpha system users reading this thread, another reason why I choses to stay with Sony is NOT because of SONY brand name associated to a DSLR system.

I chose to use a Sony DSLR because I used to own a KM 5D and upgraded to a Sony a700.

And my choices comes with a plethora of technical reasons too, not just the shiny Alpha and white SONY logo on the camera itself.

Many a time I look at other systems offered by other brands as new models comes out. But most features they offer is already what I have and need in my Sony cam.

I always strictly define what I need against what I want in a camera system. I like to be known as an Alpha system user more than a Sony system user.

Prefer to be associated with the system rather than the brand.:thumbsup:

And from time to time I will see Sony alpha users get mock at for their choices. Some are naughtier :nono: than others . And to these Sony users, you don't need to proof to others of your choices.

Just bring it out and have fun shooting.

You said it yourself... "HIGH END MODEL". You are comparing an entry-level camera to the Nikon and Canon high-end models - that only shows insecurity. Compare apples to apples. Come, you can say the same thing about the D5100 and the 600D... "Quite far from the high-end models!".

Well, the D5100's contrast detect is far better than Sony's A33/55 AF when it comes to tracking. The 600D is another story...

The D5100 only uses CDAF when it's in liveview and movie mode... a far far cry from the PDAF in the A33/A55 in all aspects, especially tracking (which is the biggest weakness of contrast detect autofocus).

Of course it's only used in live view mode. Even the contrast detect of a PEN 1 tracks better than an A55.
 

Contract detection is slower than phase detection AF, u can search youtube for comparison videos

I have 3 cameras right now. A850, A55 and E-PL2, and I can confidently say the A55's AF is faster than my EPL2, even though my EPL2 is using the newer 14-42mm mk 2 lens which has faster AF speed.

this is exactly why I moved from Oly to Sony coz of the AF speed... I've own EPL1 and E620 both cam even using the MK2 lenses of Oly still wont come close to AF speed of A33. Even my friend who is Oly user (have been using EP1/EPL1/EP2 and EPL2) said when he tries my A33 "this is too fast for me" even on video mode AF tracking is prety fast and accurate even comparing the video Af tracking of D7100 =). there's a lot of video posted in Youtude A55/A33 versus D7100 comparing the AF speed in video mode.

I am not saying this coz I am using Sony the fact that I've own an Oly and I have a friend using D7100 thats why I am saying this...

yep agree with you =) I've move to Sony from oly coz of the af and using against my kids my Oly can't keep up and half of the time I miss the moment. But I like oly for the color maybe for my photoshoot I will use Oly if given a chance to own that system again =)

U obviously dunno what u r talking about.....

LOL

I'm sorry, but that's the funniest thing I've read all day on CS. :)

And yes, I've used both. The PEN 1 was USELESS for tracking in liveview and in video. The A55 worked flawlessly.
 

Obviously there are still people in this thread who speaks without proofs.

I posted an AF speed comparison of phase detection AF and contrast detection AF in another thread before, so im just gonna cut and paste it here for everyone to see.

Here's some examples of Sony DSLT's AF:
Continuous AF in video, tracking moving cars
http://www.youtube.com/watch?v=_qoVCBFnQzY
You will notice that, due to phase AF, there is no hunting when the subject moves and the camera refocuses.

AF speed:
http://www.youtube.com/watch?v=b9nLcv6hLsQ
This video is to show the AF refocusing speed when the camera needs to quickly refocus.

Do note that the lenses used in the above 2 videos are non motorised lenses, thus their AF speed is not that fast (not the fault of the camera, its the lenses). Sony has motorised lenses (termed SSM), and those lenses are MUCH faster than their normal lenses.

Also, the A33 and A55 are Sony's entry level DSLRs. Sony will be coming out with their semi pro DSLRs later this year, and its AF speed (in video and in photo shooting) will be even faster than the entry level A33/A55.

You can compare it against the Nikon D3100's video mode, which uses contrast detection (and this is one of the fastest contrast detection AF in video in the market right now)
http://www.youtube.com/watch?v=0pOJ1eikUeQ

You'll notice that everytime the D3100 needs to refocus, the front back focusing hunting occurs. Also, most times the camera needs to stop moving for a little while, before the camera will try to focus. And whats worse is the "rubberband effect" (look at 1:28 - 1:30min, at the fences, when the camera is moving).

The front back focusing of contrast detection is very annoying in video...
