goshigoo: I think the new 14mms, like the 20mms, is just cosmetic update

I hope Panasonic release a 14mms f/2 or faster lens even it is larger than the current one (smaller than 20mm)

The 15mm is too big; I want the same as 20mm but larger aperture

goshigoo: IBIS is "unknown"?
Anyone can confirm

You are right; dpreview has updated to indicate there is no IBIS

burnymeister: The GM series m43 cameras are the first in that line that really made sense to me. The promise of m43 was always size and weight reductions no? The inclusion of an EVF and slightly larger form factor makes this an attractive option. I've used the GM1 with lenses like the 12mm f/2, 15mm f/1.7 and 45mm f/1.8 and it's a very nice combo.

Unfortunately for me, Sony proved more innovative with their RX100III and it's popup EVF and their FF line of A7 cameras. But if I was in the market for m43, this would be it.

totally agree on "The GM series m43 cameras are the first in that line that really made sense to me"

m43 is about portability; it is stupid to create the monster sized GH3 (except the video feature)

Sony is just too innovative; the new QX1 / A7 are just amazing

Poweruser: I expect a price drop for Panasonics 35-100/2.8...

Is Panasonic going to release 150 f/2.8 Prime?

TimK5: A bit pricey, but for the first time I am not totally shocked when I hear the price for a new Olympus lens. It better shows a stellar Performance like the 75mm

Is the lens collar fixed or can it be removed?

I was hoping the 7-14 f2.8 would be released first :-(

agree, it is pricey, but still reasonable; given it offers 150 f/2.8 on the long end...

much much better than Panasonic 42.5 f/1.2

In reply to:

qwertyasdf: This might be the first and last time that I say this to a M43 lens:

It's priced reasonably.
Given it's longer range than 70-200 FF lens, it is way way more versatile, and I have confidence in the IQ of a Oly HG lens. Oh....also, the 0.21x magnification, taking into account of the crop factor of M43 sensor, is class-leading.

I thought Canon 70-300 f/4-5.6 is also priced ~$1500.....

In reply to:

John C Tharp: It's hard to directly compare MFT lenses to those of larger formats, so bear with me- we should really be comparing this new Olympus to Sigma's 120-300/2.8.

While I agree that a comparison with Canon's 70-300L results in a similar field of view and a similar level of DoF control, what really matters is shutter speed. And for the sake of calculating exposure this lens is f/2.8, like the larger Sigma.

You should read this first before you say
"exposure this lens is f/2.8"

http://www.dpreview.com/articles/2666934640/what-is-equivalence-and-why-should-i-care

You can have the same shutter speed by increasing ISO...

you really have to compare it with a 80-300 f/5.6 @ FF lens

On Nikon D810 Preview preview (1575 comments in total)

A 4K video reinstalled to 1080p is better than a native 1080p video

So, even you do not have 4K TV, you can still benefit from 4k video

goshigoo: Can anyone tell me the reason for getting these lenses?
Is 40-80 mm f/4.0-5.6 @ 645 equivalent to 25-50mm f/2.8-4 @ 135 FF ?

Why don't you just get a Canon 5D III + 24-70 f/2.8L??

I am not sure if the price really justify it; but I do understand some people need ultimate IQ so they will pay whatever to get it

It makes sense

so it does look like Medium format may not always produce better IQ than 135 FF;

I see your point; you are talking about IQ at base ISO
I do agree with that, that's useful

Sorry, one more question...
Under low light situation;
Can I say the IQ of 50mm @ f/1.4 @ 135 FF @ ISO 1600 is probably better than 80mm @ f/2.8 @ 645 @ ISO 6400 under the same shutter speed ?

BTW, correct me if I am wrong, I believe they have the same FoV

#1 Larger sensor but the lenses are slower.......
40-80 mm f/4.0-5.6 @ 645 vs 24-70 f/2.8

#2 I agree leaf shutter is an advantage

Sorry guys, I am really asking here!
I thought the most important things are Fov, Dof and ISO performance?

I am not talking about super thin DoF......

I just want to ask why spending huge amount of money on medium format, while you can achieve using much cheaper 135 FF?

40-80 mm f/4.0-5.6 @ 645 cost you over 10K USD
but a 5D3 + 24-70 f/2.8 cost you much less
but it gives your the same View of field and Depth of field

well I do understand LEAF shutter in Phase One 645 gives you very fast flash sync

Because RX100 only has 1" sensor and I cannot mount another lens?

f/1.8 - f/2.8 @ 1" sensor is equivalent to only f/4.8-7.5 in 135 FF

I will get RXwhatever if it has 1" sensor AND a 8-26mm f/1 lens in a same compact body (which is not feasible)

In reply to:

Marcelobtp: One important thing to be noticed -4 ev focusing with a F2.0 lens, so only the 55 1.8 will take total advantage of this for now.

Do you still get AF via adapter? ....
