E-620. The G1 focusing engine cannot be compared to the Olympus focusing engine.

Two more months and you will have Olympus m43... better buy the E-620 now or you will be biting your socks to decide which to buy... E-620 or m43 offering from Olympus...

Bro,

Any info on the Olympus m43? Like what lens will be release, how does the body look like etc?
Since you used both E620 & G1 before, mind to share how does E620 live view contrast detection AF compare to G1?

Thanks

It might be rangefinder-style. But who knows.

You might wanna read Microcosm's E-30 diary. Check out the live-view part. Based on my usage before, I think the E-620 is comparable, if not faster than the E-30 in liveview.

I cannot talk too much about m43... just have to wait. Speculation have it that it will be far more advanced than the G1. The December release will see a more pro spec-ed model.

CDAF on the Olympus systems are way way ahead of anything else that is available on the market. Accurate and reliable are the two main points I use to compare to other systems. Only current point and shoot cameras has comparable features. It is a joy to use with compatible lenses.

Thanks bro..

I tried E-620 today at Cathay Marina. Well designed camera. I like the build of the camera body. Feel solid.
However, the SPEED of the CDAF is still slow if compare to G1. I have tried "Imager" & "Hybrid" AF, both are slow. Even High end compact camera is 'faster' than it. But may not be as accurate as E 620. Ha ha..

To me, i don't agree with what you have said:" CDAF on the Olympus systems are way way ahead of anything else that is available on the market. "

Accuracy & reliablility of E620 i am not able to tell as i dun have chance to use it for longer time. But i believe it's good.

I hope Olympus micro 4/3 CDAF will be much improve. If it's same as E-620, it will be a great disappointment.

If Olympus able to improve CDAF to G1 standard, i think E-620 be even more attractive.
To be fair, if compare to other DSLR (Nikon & Sony), E-620's CDAF is the BEST...

Million dollar question is : Which lens did you use for CDAF test?

I had a lot problems using G1 AF on fine focusing work for street photography, that is why I dropped the idea of buying it.

Would be good to hear your opinion on this.

I still stand on Olympus' AF system being one of the most reliable. I depend on it for every assignment. I can safely say my job depends on it.

Hybrid AF is not good. I hate it.

Sorry Guys , as a users of the abv 3 set before
Pansonic G1, oly E-620 and the sony A300 series.
i would say in term of speed G1 is the best follow by sony A3XX series. the e620 still need lot of improvement for CDAF

Wow.. bro.. You are the best person to give judgement. Hee..
i think your opinion will be more accurate & reliable since you used all 3 sets before.
I agree with your statement: : "the e620 still need lot of improvement for CDAF" I felt the same after trying E-620.

Thanks for clearing my doubts.

no worry as a fan of the following three brands ....
i hope that there will be no hard feeling since ultimately i does really like Panny G1 and the e620..at entry level ...it is the most well featured dslr among all the brands

It was mentioned in post #3 in this thread, "Contrast Detection Auto Focus"...not to be confused with CAF or "Continuous Auto Focus."

The standard AF for "E" cameras is Phase Detection, but newer live view cameras uses contrast detection so the mirror doesn't have to be flipped to focus, and uses the imaging sensor for focus rather than the dedicated focus sensor.

Quite interesting find eow. Other than the Sony, I have used all the cameras mentioned and had problems with G1's AF reliability, especially when shooting with 45-200mm lens. Was there any setting that you had used that overcame that problem?

On tight cropped shots, with subjects in foreground and background close together, the G1's AF does not seem to be able to "creep between" subjects at the rear to lock into them, causing me to always override and use manual focusing. How do you overcome that?

DaXiong, again I would like to check with you, what lens was used when you were testing the E-620 when you were testing the camera? I am curious to find out because that would give me a better idea on the differences between CDAF enabled lenses and their speeds. Thank you.

I think we have gone two directions here in the discussion, of which I am saying CDAF reliability and you were referring to speed.

And of course, like you said, CDAF is new and definitely will be improving always.

We were were referring to the speed of the CDAF. af reliability wise G1 and lx3 had a unique feature in it af tracking that allow yr camera to prelock on yr designated subject even when the ambient light is less than -1ev which even my e420 will falter even in normal phase detection af mode .
that once locked even when u shift and move around..the focusing point will remain tracked on the subject unless u forcibly bring it out of sight or there a sudden interruption of an foreign object in between the camera and the subject..it doesn't work 100% on all surfaces but it was good enough and fun for most circumstances

I checked online reviews of the Sony A-3xx series but can find no mention of CDAF on the Sony body. Was it added in a firmware update? I thought the A-3xx only does PDAF in LiveView.

Hmm, so i should go with Panny G1 instead?

On a whole, G1 would give me better user experience and image quality?

if you intend to stick with the kit lenses and have no experience with a dslr or intend to move to a dslr, then the G1 should meet your needs.

the sensors on the E620 and G1 are similar but each manufacturer processes the images differently. both are capable of excellent image quality.

else, try out both cameras and decide which suits you better. the G1 Intelligent Auto mode is a very good auto mode.

please note that both camera do not and will not have a movie mode. if that is important to you, please look at the Panasonic GH1 or wait for the micro four-thirds offerings from Olympus from mid-June.

No, in fact the E-330 had no CDAF at all (and no, Olympus never bothered to update the firmware to add that feature).
