Jefftan: I am a bit confused and if some expert could kindly answer my question
for mirrorless with only CDAF which is my NEX-5N and GM1, I know in low light AF I should use the largest aperture for a long time

but using AF-C is a new idea to me, I only use AF-S and especially for NEX-5N is a problem in very low light condition, by the way GM1 much better in extreme low light
Should I use AF-C in low light for CDAF mirrorless?

Is there any drawback like mention in article " if it's so dark you're experiencing hunting (below -3EV), you'll want to switch to AF-S so that once your camera locks focus, it doesn't try to refocus which may send it in to a long hunt. Why the hunt? Because PDAF sensors may cease to function, at which point the camera reverts to CDAF"

Thanks for the reply

On Bang for the Buck: Olympus OM-D E-M10 II Review article (524 comments in total)

"softening brought about by shutter shock. The E-M10 II suffers from the same problem but, unlike G7, offers an electronic first curtain mode (called 0sec Anti-Shock) that eliminates it "

May I ask the reviewer or anyone in the know, Does it mean that I should always use electronic shutter in GM1 (probably same shutter shock problem as G7) or only in certain shutter speed?

Get me confused. My understanding is that using electronic shutter bring about added noise and rolling shutter effect (is this effect only for moving subjects?) and should be avoid when standard shutter can be used (1/500 or slower)

But than what about this shutter shock problem? Thanks

Jefftan: I am using GM5 and to me the only reason why I would want to double the weight and adding 200 gram is 5 axis IS
Can one really get consistent sharp pics in 1/3 seconds at wide angle? (24-28mm equivalent?)

If true I would be interested, I am not getting consistent sharp pics even at 1/15 with kit lens at wide angle

Can the reviewer or someone with experience in this Olympus 5 axis IS comment please?

2 stop at wid angle is quite disappointing for the supposedly miracle of 5 axis IS

On Bang for the Buck: Olympus OM-D E-M10 II Review article (524 comments in total)

In 2015 can u really sell a mid range camera without 4K and with old sensor?
almost 400 gram is heavy in my opinion for a small sensor camera without weather sealing. Remember GM1/5 with the same sensor is only 200 gram and that is with magnesium alloy frame which EM10 II is not

The only interesting feature this camera has is 5 axis, even this is rate lower than EM5 II (5 stop vs 4 stop)
not interesting or exciting

Thanks for the reply but what is this mean?
"A lot of cameras tend to be less picky with AF-C even if set to focus priority and it may not be picky enough"
thanks

Jennyhappy2: Sorry, but unless you plan on changing lenses, the RX100 III surpasses the GM1 and GM5.

"you would prefer the higher MP count and smaller sensor found in the RX100 for more DOF"

how many more real detail are you getting from a smaller sensor with supposedly 4 more megapixel

I would say at base ISO almost none, in high ISO less (of course I know lens 2 stop faster for RX100) but GM1 low light with excellent IS is more than enough (good to 1/10 F3.5 ISO 3200)

of all these type of camera available now

Panasonic GM1 is the best for price and IQ (both sensor and lens excellent). This is my judgement. You guys can choose to believe or not

ttran88: $1000 for this camera, why? I can buy 4 GM1 and leave it in different places and never need to carry any camera around with me. I can leave One in the toilet, one in the yard, one in basement and one in the ladies room. Or just buy one GM1 and use the remaining $600 to hire someone to carry it for you. Down with Sony RX100IV!!!

Where can you get Gm1 for $250?

Jefftan: Anyone care to compare with Panasonic GM1 which I just got in Japan for about US$380

In RAW both in ISO 100 and ISO 3200, IQ simply much better for GM1, very obvious

Really don't understand the excitment for this overpriced $1000 camera

By the way GM1 is very good, a greatly under appreciated camera

"But if I can't do selfies with out getting confused it's a no sale for me"

sorry I don't do selfie at all. This is a question I can't answered. It doesn't have a flip up screen only a very useful touch screen with touch shutter and touch AF/AE.

"Does the Japan GM1 have an English menu? "

Yes, very easy. I don't understand Japanese too. When you start the camera it is in Japanese (which should be expected) but can easily change to English menu

Jefftan: Low night capability of Panasonic GM1 is underated because of its excellent image stabilization
When I am testing the camera I take 2 pics that is 1 second at ISO 3200, yes 1 second but the image is not blur by handshake. I can't post image here otherwise I will do so
I don't know how typical this is. I don't have particular steady hands. Another testing pic at 1/3 sec turn out blur
but in practical use I think handheld to 1/10 sec at 24mm equivalent should be no problem

"it is only the antiquated Mega OIS system rather than Panasonic's more state-of-the-art Power OIS system."

It may be antiquated but still very powerful in my real life use of it

"if you can keep the shutter speed below 1/500th. above that the electronic shutter limits the dynamic range."

Why? Please explain. Thanks

Jefftan: People who are interested in RX100 IV should seriously consider GM1, this is written by a happy new owner

way exceed my expectation
sharp lens, excellent IQ, fast auto-focus, good image stabilization,fast operation

Mainly because of the great sharp lens, to my great surprise IQ even beat my NEX-5N with Sony 10-18mm F4 lens (already much better than the garbage 16-50mm kit)

why by this overpriced camera? just for being a little bit smaller?

And tolerate lower IQ and much more expensive? It is your money but I really can't understand

The value of fast lens and hence RX100 superiourity over Panasonic GM1 is not true for a lot of people.
1. for daytime landscape photo you need small aperture for more DOF
2. in real low light situation, GM1 is still very good at ISO 3200 and can easily handheld to 1/10 second which will cover almost all reasonable shooting condition
On paper a fast lens is better than slow lens but for most people in most used shooting condition, is that really true? I said no.

"You clearly have a broken NEX!"

Do you said this base on real experience? I have both camera and use both extensively during my last trip. I admit I don't do detail scientific comparison so only general impression

GM1 focuse faster, make less metering errors than NEX-5N(I suspect NEX takes longer to meter and I fire too fast) ,seem sharper (but I up the shaprness setting 1 level in color setting "standard")

and most important point is although MFT is supposedly behind NEX in noise for ISO 3200 but for practical use when I try to take a pic of something very dark at ISO 3200 in a temple, I can't hold my NEX still enough for blur free photo but not very difficult for GM1.

Therefore GM1 has better real life low light performance because of better image stabilization(or easier hand holding due to lower weight)

One more practical concern is if you shoot Jpeg, they have very different interpretation of green color, depend on your preference you may not like either one

"Sorry, but unless you plan on changing lenses, the RX100 III surpasses the GM1 and GM5"

I disagree with you. It all depend on your use.

For me a mostly daytime landscape photographer. I use low ISO and prefer more not less DOF (smaller aperture). Which camera is better is obvious.

"F1.8-2.8 vs F3.5-5.6 in short compare Sony at ISO 400 vs the Panasonic at ISO 1600."

I understand your point. It really depend on your use. For me a mostly daytime landscape photographer. I use low ISO and prefer more not less DOF (smaller aperture)

Which camera is better is obvious. May not be the same for other types of photographers
