When you think of some of the trivial stuff we all moan about this gent is a real inspiration

On article Panasonic Lumix DMC-LX100 Review (1018 comments in total)
In reply to:

idou: Judging by the graph in the above article, the LX100 has basically a full stop of extra light gathering compared to the Sony RX100 III/ IV over almost the whole zoom range. Since these cameras are trading a lot off their F stop lenses, this seems like a pretty big deal. Strange nobody else seems to have commented on that. Would people be still buying the RX100 IV if it was more accurately labelled as a 24-70 F 2.6-3.6 ?

Richard, bearing in mind that the Sony RX100 III/IV sensor actually performs a bit better than the size difference between it and mFT would suggest. And the fact that the LX100 uses a cropped portion of the GX7 16mp sensor some 80% or so which would only give it a 50% greater area than the Sony. This would only give the LX100 a 0.5 stop advantage assuming identical sensor technology , given that the Sony 1” sensor is a little better than this , and given the MP advantage of the Sony RX100 III/IV at the same output size I do not think that the LX100 has anywhere near a one stop advantage .
I have both the FZ1000 and GX7 in most scenarios the difference is small , you really need to be shooting at very high ISO where it is not a case of which is good but just which is least bad. Though for me the fact that the LX100 is £250 cheaper makes it a strong favourite to get my money

I have always had a fondness for Pentax my first "real camera" when I was a teenager was the ME. My first "serious camera" the LX. Pentax with their sensor shift IS, the high res mode and record of building very good high end gear makes me think that they will deliver a very good camera.

Intermittentoverexposure: Just as everyone is looking to FF mirrorless, Pentax releases a FF DSL. /facepalm

Contrary to what many mirrorless fans imagine the fact remains that DSLR’s still make up 74.5% of all interchangeable lens cameras. Remember that the first mFT mirrorless camera the Panasonic G1 came out in 2008. The competition in mirrorless is also much greater than in the DSLR market which is hugely dominated by Canon and Nikon. The mirrorless market which makes up 25.5% is shared between Olympus Panasonic Sony Canon Fuji Nikon Pentax

As a side note though I still use FF DSLR's I have been a keen mFT user since 2009

In reply to:

jim stirling: Is it possible that Canon has some corrections built-in to their RAW file such as CA correction that make the native lens look better on a Canon body? While both lenses mounted on the Sony A7r2 show minimal differences in performance.

Rishi, I was just looking at possible reasons for the poor performance on Canon.Though copy variation seems the most obvious. As a mFT user our system obviously has access to in-built software corrections by standard. At least for some aspects it seems possible that DSLR’s could do the same

Thanks for all the work and this multi-aperture style of test is great cheers

Scottelly: 3 minute video recording limit in 4K is a sad feature. I wonder if the two-year-old Panasonic GH4 has this limit.

This video mentions the 3min sections which probably equate to the splits you mention .

Several cameras with 4K shoot in a cropped mode my GH4 is 2.2x crop, my GX8 is 2.4

I am pretty sure it records up to 30min in 3 min section, why it does it this way I don't know lol

steelhead3: `1/3 the weight....give me a break unless you are comparing it to a 300 2.8.

I don't know the performance of any of the longer telephotos thankfully for my wallet I normally shoot at the wider end of town

@ Astrotripper the 24mp D7200 has a built0in 1.3x crop mode which results in an effective 2x crop with a roughly 15.4mp file resulting. In this mode the D7200 has enhanced AF , higher FPS and still uses RAW

noflashplease: This is very expensive indeed compared to equivalent lenses from Canon, Nikon and even Pentax. I would imagine that an upcoming Pentax full frame body and 300mm F4 would end up being cheaper than combining this Olympus lens with an E-M1.

Marty, equivalence is not a theory it is a simple fact and JJ explains all the requirements very clearly. For this type of long telephoto shooting I believe the bird guys { of whom I am definitely not one } work under the simple pixels on bird mantra.

The Nikon PF F4 is only 60% the weight of the Olympus and £700 cheaper here in the UK, The Canon 300mm F4 L USM while being a little lighter than the Olympus 300mm F4 also comes in at less than half the £2199 price of the Olympus { £899 } . I am curious to see how these lenses would perform on a mFT camera . There are several bird shooters in the mFt forum using adapted FF lenses

Not necessarily the Nikon APS models have a 24mp sensor the D7200 has a 1.3 crop mode that gives you the same 2x crop factor as the 300mm F/4 with a 16mp file

TorsteinH: That BSI sensor would be nice in a new Olympus EM1 II ...

If you look at the NX1 compared to the D7200 { Sony APS sensor} it lags behind in DR , colour depth, matches it at high ISO. Cropping it down to mFT would offer no advanatges over the latest mFT sensor.

BSI seems to be more about speed of performance rather than any real image quality gains

Andreas Stuebs: Samsung was never going to make it alone, they lacked the street cred. What Samsung forgot to do is to forge an alliance with another company to create an "APS-C mirrorless standard" much like Olympus and Panasonic created the µ4/3 standard.
Would Fuji have licenced their mount to Samsung? Or even "opened" it the same way that µ4/3 is a published configuration.
With Samsung going, there is only Fuji and Sony left as APS-C mirrorless for enthusiasts. And with Sony I am not quite sure, the A6000 is getting a bit long in the tooth and a replacement is not in sight.

I would have to debate Fuji "doing well" they have a tiny share of the mirrorless market {down around 5%} and obviously no DSLR'S

PORTRAIT: IF and I repeat, IF this rumour turn out real,I will be sad to see them exiting the Camera biz.We need competitors here, I respect Samsung, there are capable of AMAZING electronic products..I almost ended up buying the very first NX10, remember? for instance, Fuji wasn't even around at that time,and it was the only APC sensor ILC contender besides the very first Sony Nex 3... the question is WHY???..I can't wrap around my head...

Olympus carried the camera divisons massive losses for several years and I would imagine their back in profit claim may not be so come the end of the financial year

entoman: A realistic and very relevant comparison between Sony A7iiR, Nikon D810 and Canon 5DsR can be found here:

https://fstoppers.com/originals/fstoppers-reviews-canon-5dsr-sony-a7rii-and-nikon-d810-89896

Essential reading for anyone choosing between these 3 cameras.

Yes i have seen a few of the fstoppers posts and Ken Rockwell is a fair comparison lol

Angrymagpie: Would love to hear about how the RX100IV wins over the LX100. I'm considering picking up the LX100 over the RX100 mkIV - as a user of the original RX100, I really like the camera except that it's a handful with manual control. I was under the impression that the LX100 has superior manual control & better image quality and performance (in terms of AF?), and that the only real disadvantage is it's relatively larger size?

The LX100 uses an 80% crop of the GX7 mFT sensor if you look at the RAW comparisons with the RX1004 at low ISO the RX1004 is actually a little better assuming the same output size. Up to 800ISO any differences are pretty small, from 1600ISO upwards the Panasonic pulls ahead though never by more than 0.75 of a stop. As I say this is assuming the same print or web size. I have both the FZ1000 and GX7 .

Though the LX100 here in the UK has a rather significant advantage it is a full £300 cheaper than the RX100V!

better to see this
http://www.dpreview.com/forums/post/56535384

How exactly is an unsubstantiated post on a dpreview forum proof of anything? Let's face it there is no shortage of bizarre and wild posts on dpreview. I am not saying that it is not true just I would like a rather more concrete link you know like manufacturer posts or from well informed sources. Either way I don’t mind who makes the lenses but rather how they perform
