I reckon it would be useful to share some of my on-the-field thoughts on this camera.

All in all I am pretty satisfied wih this little camera. It is very light. I can stuff it into a small pouch and just walk around without feeling much extra weight on me. In fact, I was deliberating whether to carry my 800g dSLR or the Panny G1. At least while walking around, I definitely feel like it was a great decision to carry the 400g camera instead. Ofcourse, my experience is set against the following environment - It was a rainy day and lighting was poor.

Here is what I liked about the camera:

- ISOs of 400-800 is very usable. This is the trump card against P&S. Even an excellent P&S will start to struggle at ISO 400

- The LCD is just excellent and the EVF is way better than any others in the market (at least those of similar price range)

- The weight and size is great for travelling, especially if you need to walk a bit. Folks with kids and a huge bag to carry around will appreciate this a lot. Grabbing the camera and the kit lens in one hand is comfortable.

- The swivel LCD is great for finding new angles.

- The performance is definitely snappier than any P&S out there, close to or exceeding some entry level dSLRs. Very impressive considering that it is using Contrast Detect all the time. Contrast Detect on my 450D can take up to 3-4 seconds.

- I like the feature which does a countdown during long exposure. On my other SLRs, I feel like an idiot then the exposure is 30 seconds and I have to count to myself (one-thousand, two thousand..) to have an idea when the shot is going to be completed. On the G1, there is a timer which counts down how many more seconds is left for the exposure. :thumbsup::thumbsup::thumbsup:

- Battery life is pretty good....

- Details captured are very good.

So up to this point, you would have realized that all the 'likes' are almost lifted from other reviews on the G1. Well, that is because what the other said are true in these aspect.

Now on to some of the quibbles that I found with this camera. Note: Some of this could be because it is my first time using it and I'm not really familiar with some of the settings.

- For normal dSLRs, I don't mind leaving them ON most of the time. This is because, without Live View, power consumption should not be that high. Therefore, whenever I needed to shoot, the camera was ready. With the G1, since either Live View or EVF is ON all the time, I felt the need to turn it off every time I put it down, in order to save power. This made it a bit more cumbersome when I needed to take the next shot.

- If you playback your shots after the previous shot (which is what most people would do to check the result of the shot), the EVF will be stuck in playback mode as well. So when you view through the EVF for the next shot, you will be surprised to see the previous shot instead of the current live view. Half pressing the shutter fixes this but I find it a bit of a bother to waste a second or two doing that every time. I felt disrupted and while this may be a minor quibble to some but it irritates me a bit. Panasonic engineers can easily fix this by allowing the firmware to exit playback mode whenever it detects a face at the EVF and switches the back LCD off, a setting which can be turned on or off.

- I am not sure if this can be changed but the EVF does an immediate preview after every shot, this could be a hindrance when I need to take the following shot. I think the EVF should be at least configurable to only show live view all the time. Any previews or playback should only be shown on the back LCD.

- When taking shots with a strong backlight, I felt that the area around the lights gets washed quite out a bit. Some of the shots of the trees with sunlight behind them had this effect and the Waterfall picture above illustrates this. Ofcourse, perhaps some Film Mode settings may help me and PP can definitely fix this easily but as of now, it bothers me a bit . My using the lens hood could have contributed to the effect too, as I wanted to explore traveling as with as compact an equipment as I can.

- When taking shots with long exposure NR turned on, it takes as much time as the exposure time for processing. Eg, a shot with 30 seconds exposure time will take another 30 seconds to process. There is a countdown timer for this as well which is good but why so long to process?

- I also feel that my pictures are a little over exposed most of the time. EV compensation of up to -1 fixes some of these issues. [EDITED: Perhaps some film mode can help here]

- The default color settings also looks a bit washed out...Again I believe the Film Mode can help fix this, I haven't actually got to experimenting on some of the modes yet. [EDITED: I changed the film mode to Dynamic and the colors are very much brighter]

- Just note that when using the swivel feature of the back LCD, one needs to flip out the LCD fully and turn it around. Half lifting the LCD which I was doing in the beginning, would make it even more complicated to angle.

- Some settings such as metering mode, requires going through the menu to change. [EDITED: This can be changed by using the Fn button]

- The built-in flash, at 10.5, may be a little weak at times.

- As mentioned by some reviews, changing lenses is a little scary because of the exposed sensor.

- The On-OFF switch and some other controls feels a tad flimsy at times.

These are some of the minor quibbles I found with this camera. Again, as I mentioned, I haven't fully explored all the features of the camera and my first shots are out-of-camera JPEGs not RAW. Besides, these are not serious deal breakers that would likely to stop anyone buying the cameras. With time, I am sure, I am just going to like it more.

Summary

All in all, a very compelling package to replace some bridging or P&S camera. The performance is very close to dSLRs out there although I find the best entry level dSLRs may still hold some significant edge over the G1. I will definitely not be dumping my dSLR for the G1. However, considering the overall size and weight advantages and the undeniable hip factor, I think the G1 has a very good market carved out for the following groups:

a) People who have serious dSLRs but would like a travel camera which can still do a very decent job. The trendly looks of G1 fits right into those situations in which you don't want to look too geeky carrying around a chunky dSLR and make your friends nervous but would still want to take good pictures. The red one is really good for this.

b) Trendy people who would like to get a bit more serious in taking photos but would still want to carry hip equipments not too different from the colorful Sony and Casio P&S

c) 4/3 and m4/3 enthusiasts will current 4/3 accessories or people who would just like to try out the possibilities of the m4/3 technologies with adapters for Leica and other mounts

All in all, if marketed and executed properly, the Panasonic G1 could very well be the iPod/iPhone or the Wii of the dSLR market. Note that the iPhones has a gazillion flaws, but it is still the most exciting thing that happened to the handphone industry since the Motorola StarTac. The Panny G1 definitely have very much less flaws than the iPhone.

Does anyone know what is a good wide-angle converter to get?

I thought since the 14mm (28mm equiv) is not as wide as I would like it to be, I am thinking of getting a 0.5x-0.7x multiplier or something.

Does anyone have any experience with such multipliers/wide angle converter?
 

"- Some settings such as metering mode, requires going through the menu to change"

I just realized that the Fn button can be used to change metering mode :D
 

Thanks for the :thumbsup:

It was hand held and I support myself on a beam. Took a few shots to make sure I get it . I was testing the OIS :D

The settings are:

Exposure: 0.1 sec (1/10)
Aperture: f/5.6
Focal Length: 14 mm
ISO Speed: 400
Exposure Bias: -1 EV


Out of camera JPEG, no adjustments.

Thanks! I am liking the sensor's DR more ........

Problem with using converters is that (1) It adds weight to the front of the lens, that might cause damage if the camera/lens are not handled with care (2) image quality tends to suffer, especially when used with lower end third party adapters. (3) it is usually a pain to use these screw on adaptors. But that is really not a big issue.

Something to think about.
 

Are you guys getting the M to M43 or the LTM to M43?
 

As mentioned, I am consolidating all threads on the Panasonic G1 into this one thread for the benefit of those non regular forumers who might be lost in the sea of multi thread discussion of seemingly the same thing.

Please continue discussions with all things regarding the Panasonic G1 in this thread please, thank you all.

Hi,

How can we talk about DR without a HDR sample :D hehehe....

When I read about the 6 Frame bracketing feature of the G1, I knew I had to do a HDR :D

Here is a quick and dirty try with 6 frame bracketing 1/3 stops apart...actually I think it was 7 frames.

Just checked from MS Color!

They already have the Olympus to MicroFT adapter available for $280 :)

The Adapter seems quite thick and will increase the distance of the lens from the sensor quite a bit! Will it not increase the magnification of the lens? Just like using an extension tube? :dunno:

On the other hand, Using the ZD 25 f2.8 on a G1 will be great ;)

I think the increase in distance is to make up for the reduced lens to sensor distance of m4/3 from 40mm to 20mm. See this illustration

http://a.img-dpreview.com/news/0808/MicroFourThirdsDiag.jpg

But I heard that the focusing time for the traditional 4/3 lenses is considerably slower. This is because the motor of the m4/3 lenses are optimized for contrast detect operations involving numerous small adjustments. Any truths in that?

That makes sense... And that is why the MFT cannot be used on the Traditional FT bodies!

But slow focusing is a bit of a concern :dunno: But fromthe traditional FT I am only looking at the 25mm f2.8 PC and 50mm f2 Macro

The mFT mount is smaller than the FT and the mFT lenses' flange may be longer, too, and hence gets into the mirror assembly way.
 

Bros...

May i know currently which Zuiko lens AF is working fine with G1 + Adapter?
Thanks

Review of G1 vs 450D (Rebel Xsi):

Full review here.

Exerpt:

"And it takes a pretty darn good picture too. Because the sensor is smaller than modern APS-C-sized digital SLRs, you'd expect image quality to be slightly lower, but printed results really show surprising parity. I took a couple of 13x19-inch print samples from the Panasonic G1 and the Canon Rebel XSi down to the lab guys and asked them to pick their favorites. It was too close to call. There were preferences in some areas, with the XSi showing slightly more detail and higher contrast than the G1, but in other areas, the G1 actually delivered more detail, especially at lower ISOs; but this also differed by subject texture, color, and contrast. Both cameras produce excellent image quality, which is pretty high praise for the live-view-only Panasonic G1."

I have really high regards for the Rebel XSi and if the G1 can match up to the XSi, I think it is definitely a camera worth owning.

Hi Lightsabre,

Thanks for the detail explaination. Just can't wait to see the IQ for 20mm f1.7...
I just bought a G1 Black from Cathay Photo. Very satisfy with their excellent service. :thumbsup:
