Panasonic GH3 review published
13

I know it's taken a while (even after we got a camera to work on), but our GH3 review is finally ready.

We worked with Andrew Reid at EOSHD to make sure we really did justice to the camera's video capabilities, so we hope you find something useful or interesting in there:

Re: Panasonic GH3 review

About time!! Good review but there are couple of things that I did not understand when comparing with OM-D review.

- Both have same score for RAW files and OM-D has little better score in JPEG but it has significantly better score in low light/high iso?

- How come OM-D focus and metering better than GH3?

Thanks

The low light/high iso element of image quality is considered separately (if it was also included in the JPEG score, it would essentially be double-counted) and that's really the area (in JPEG) where the E-M5 stands apart from the GH3.

The focus of the two cameras is similarly good but the GH3 has the tendency towards underexposure that we've seen before in Panasonics. Not to a terrible degree, but enough for it to be marked down a touch.

Hi All

So on DXO, the GH3 Signal to Noise graph virtually overlaps the OM-D, virtually identical.

So does this mean the better noise performance shown in DP reviews test is not allowing for Olympus's fairly overstated ISO setting versus actual ISO?

Thanks for the good review. You have confirmed my concerns about the view finder, which is indeed disappointing for a flagship camera.

The view finder is the deal breaker for me, making the purchase of the GH3 out of question for me.

The difference in the scoring is, as I say above, mainly down to the difference in JPEG performance at high ISO. The OM-D's noise reduction is better than the GH3's - providing a better balance of detail and noise.

The difference in ISO between the two cameras is 1/3rd of a stop, when tested using the part of the standard that the manufacturers use.

What DxO shows you is that the two manufacturers are using different Raw values to give middle grey in the JPEG - this is not mis-stating ISO, it's a perfectly allowable part of the standard. DxO themselves confirm there is no expectation that stated ISO and their 'measured ISO' will correspond to one another. (Note that they do not use the term 'actual' ISO).

Re: Panasonic GH3 review

Thanks, Richard.

I think the review is confirming what most have expected. Great to have another flagship choice in M43.  I believe the GH3 and the E-M5 will be compared and debated everyday on this forum for the next 3 months.  

Here's my take:

GH3 - better handling, better ergonomics (dials and buttons), fully articulated LCD, the best video around and the best hybrid, automatic CA correction

E-M5 - smaller, lighter, cheaper, better EVF, better JPEG (colour and noise), and the best IBIS around (stabilsing any lens that is mounted on it)

And there is also the subjective matter of looks, retro or no-nonsense style.

Very nice job

I won't be ditching the OMD for one, I'm mainly a still photo type and that IBIS really spoils you, but I thought it was a smart move to call in a video expert to work it over from a video perspective, as that's where it really shines.

What terrific choices we have...

Yes, yes, we know.

We tirelessly know.

How many times are you going to tell us?

The amount of functionality in this camera is mind boggling - I don't think the industry is quite ready to level off. It must be tough keeping the review to 20 pages.

I can see by the table of contents and skimming though, a lot of work and effort was put into this. Thank you!

Just to add something that for me is important:

E-M5: 1/250s of flash sync vs. 1/160s. WHY Pany??

Nice review. I've had the camera for a couple of months and picked a few things from what I've read so far.

it does not confirm you allegations... it just says that visually impaired people like you (those who need to wear glasses ) do not see all the image sharp - "you'll rarely see the whole screen as sharp if you wear glasses"... you were alleging that everybody doesn't... just compare what is written in review w/ your previous musings.

the situation is that you really don't have 1/250 w/ EM5 all the time w/ all flashes.

Read this then...

"However, we found the viewfinder optics to be disappointing - it's difficult to ever see the whole panel and the corners are fuzzy unless you look straight at them (a problem that gets even worse if you wear glasses). "

take Adobe DNG converter, convert raw files to DNG and then see the value of "baseline exposure" tag for both cameras ... that will show the hidden exposure correction that Adobe raw converters (ACR and LR) will do behind the scenes for Olympus and for Panasonic... the difference is 0.5 EV... you will not see that in ACR/LR user interface though... you can't switch that off unless you creare a custom .dcp profile and force that tag to be 0 for both cameras.
