Don051348: Interesting concept, but sometimes these so called "revolutionary" technological advances typically only yield minor, very minor, or something the average person could not even see improvements in IQ. Sort of like the new "revolutionary" curved LED TV's. For the life of me I cannot see how a curved TV screen will improve my viewing experience.
What about improvements in size/weigth/price/reliability of the lenses ? I think such improvements are valuable as well
The name Petzval was mentioned. There is a nice museum dedicated to this industrious and creative man (to whom photography owes its theoretical foundations) in his birthplace: http://www.stm-ke.sk/index.php/sk/pobocky-2/muzeum-j-m-petzvala-v-spisskej-belej
Enthusiasts of history of photography finding themselves in the region would cetrainly find some material of interest there.
There's one point I missed in this otherwise well articulated opinion : the historical perspective. Several ears ago, "bridge" meant something completelly different than the "superzoom" of today. Compared to today's superzooms:
- the sensor sizes were bigger, at least 1/1.7"- the reach was much more limited (to around 300-400mm)- lenses were faster- optics manufacturing quality was not of cheap feeling and reputation.
I'm talking about devices like Sony F717, F828, Fuji cameras (S6500fd, S9XXX, S100fs, S200exr), Panasonic FZ30, FZ50, Minolta AXXX, etc.
Sadly, this category of devices died out - the last one of them was probably Fuji X-S1 (but that one was unfortunatelly hampered by the overambitious lens design). Their extinction coincides very well with the advent of mirrorless, but also with arrival of their low-cost (but high zoom) siblings - the superzooms.
It seems that the true "bridge" category is back. But the ingredients are still the same.
W5JCK: It's hard to believe today is the 70th anniversary of the D-Day invasion into Normandy. A good day to remember all the sacrifices that were made on this day so long ago, and all the sacrifices that were made throughout the war on so many beaches throughout the SW Pacific Islands, the Far East, North Africa, Sicily, and Italy. Most of the veterans are now gone including my Dad all my uncles who fought during WWII. May they rest in peace. We should be so thankful that they sacrificed so much to stop the world from destroying itself.
I would like to assure you, that there awlays will be many people in every nation, who will pay due respect to Russia's holy sacrifice in years 1941-1945.
sonics: We should always remember the sacrifices made that day. If it wasn't for the allied landings in Normandy Stalin would haven conquered the whole of Germany, Austria, Netherlands, Belgium and prolly part of France.
@Zzzorki: Im with you in this. Had Stalin wanted the western Europe, why did he then repeatedly urge the western allies into opening the western front. He wanted his buffer zone. The availability of the strategic depth proved crucial many times in the Russian history.
Anyone performing apologetics for this product: please have a look at samples of its predecessor, ZS15. Then you'll see that 1/2.3" can be done right.
No extreme highlight overexposures, no unpleasant corner softness.
webrunner5: God, those are pretty terrible. Imagine going on a vacation of a lifetime and coming back to show the shots to your family, friends. Jesus, who thought this camera was a GOOD idea to make in this day and age?
Barney, I disagree. Do yourself a favor and look at gallery of ZS15 sample images. You won't find all the painful overexposures, no pronounced corner softness abundant in this ZS40 gallery.
Probably because Panasonic still respected their customers and wanted to provide a decent camera in 2012 (as opposed to 2014 ?).
In 2012 they considered 12MPix sensor and lens with 4.6-68.8 mm focals to provide a good balance of specs vs IQ. In 2014 they obviously don't care about balancing anything.
Man, this looks like m43-envy. Think of white Lumix G3.
Excessive NR - at it's worst. The details of the hair around the guy's ear are unacceptably wiped.
I'd say they didn't utilize watercoloring noise reduction (Fuji style) but rather their NR involves (besides other things) significant reduction of local contrast. The result exhibits haze (in the luma channel) and bleeding (in the chroma channel) in quite significant amounts.
Overall - the camera offers the usual small sensor output, rather slow lens (also usual in the dying market segment of small sensor travelzooms). Nothing ground-breakiung, besides the advanced 5-axis IS. However, efficiency of the stabilization can be hardly judged from the sample images.
minzaw: Compact=?? definition
It is compact, iff every open cover of it has finite subcover.
If we're talking Euclidean, then it's the same thing as being closed and bounded at the same time
radissimo: For a second I was thinking about this kit, but why not get Canon G x1 mark II with nice bright zoom lens, bigger sensor and for less?
Neviem, ako je na tom G1X2, ale jednotka mala šeredne pomalé ostrenie. Naopak, Panasonic má ostrenie bleskurýchle.
The cams manufacturers went crazy pricewise lately.
BTW, I'd like to ask the ones who remember 1980s: how much did an average Joe have to work to buy a decent film camera ? I've got a feeling that photography (if one doesn't want to go P&S pinhead way) has really become unaccessible to average population of the world - as opposed to much of the 20th century.
Judging by this : have we really progressed as a civilization ? As a child I was told that in 21st century we'll live in some kind of futuristic paradise. Instead, buying a decent photographic gear has become inaccessible to most.
rfsIII: In my opinion DPReveiw is leading readers down a dangerous dead-end path with all this "equivalent aperture range." The whole silly business started with a post on one photographer's website and has now grown into a weird cult of people who are angry all the time about f/stops and love to argue with anyone who doesn't profess unwavering faith in their precepts. And worse, it completely misses the point of the exposure triangle. To get more out of your camera you need to understand the relationship between f-stop, shutter speed, and ISO but this new religion you people have adopted throws that out and makes readers think that the surface area of the sensor is in some undefined way related. Converts go on and on about twice or four or 16 times as much light hitting a larger sensor than a smaller one as though that matters. Unless you are dealing with bellows or other real exposure-changing variables, from an exposure point of view it doesn't matter what size sensor you use.
@rfsIII: partly agree.
I myself believe there are two sides of the issue : absolute one and relative one.
In absolute terms (and that relates to better IQ for a given ISO & f-stop), larges sensor is really hit by more light then smaller sensor.
In relative terms, an unit of the sensor area is hit by the same amount of light (given constant ISO, exposition time and f-stop), regardless of sensor size. This is the exposure triangle thing you mentioned.
The readers with basics in mathematical "measure theory" are probably better prepared to grasp the nuances of the concepts related.
Rachotilko: regarding equivalent aperture, You have to differentiate :
a, total amount of light - in that case equivalence applies. It means that given the f-number (for example f/2.8), the FF sensor receives four times as much light as m43.Hence for the same ISO, scene, f-number, exposition times, the whole FF image is created using four times as much light as whole m43 image.
b, amount of light *per-area* - in this case equivalence does NOT apply. It means that given the same exposition time and f-number, an unit of area (such as square milimeter) receives the same amount of light, regardless of sensor size. Hence for the same ISO, scene, f-number, the *same* exposition time is required for proper exposition for all sensor sizes.
you're right that it was mostly about clarification: that in some respects (namely the exposition time) the f/2.8 = f/2.8 regardless of sensor size.
But I disagree that it is irelevant to making purchasing desicions: since exposition times surely are relevant.
Sirandar: Finally a successor to what Panasonic started with the FZ30 and abandoned.
If I didn't already have a camera that produces better images than the RX10, I would probably buy one when the price drops.
Looking at the image quality it does seem that the RX10 has a considerable penalty in both high ISO detail and dynamic range compared to M4/3 BUT in terms of actual use, in many ways the weather sealing and the flexibility on not having to change lenses all the time offsets the reduced image quality and slightly slow AF.
If you have to change lenses you have missed the picture opportunity.
I loved my Pana FZ30 and still have it, and I used it long after cameras with much better image quality and dynamic range were available for the simple reason that when the light was good it was always up to the task. The lack of dynamic range and the slow tele end were what made me move on.
I really think that having a good M43 standard zoom (3.5x) gives you much better versatility than the 10x zoom of FZ30 (or FZ50).
The missing default reach can be easily compensated for by cropping: this is what the smaller sensor size does anyway.
regarding equivalent aperture, You have to differentiate :
Thank you for nice review of a nice cam.
However, I expected that after reading it I'd be informed about how good the lens is, esp. wide open. After all, that's the most significant selling point of the product - since the whole concept stands&falls upon the lens resolution @F2.8.
Unfortunatelly, almost all of the samples are taken with aperture narrower than F4. Why is that ?
AKH: Impressive that the IQ is about the same level as the almost 7 year old Nikon D300.
Are you uninformed or do you spread the fallacies purposely ?
According to DxOMark ISO-dependent SNR and DR curves, E-M10 is (compared to D300):
1, by 1/3 stop better in terms of signal-to-noise ratio all over the ISO range
2, by almost 1 stop better in terms of dynamic range - with the exception of lowest ISO values.
Besides that, you'll get much smaller/sexier cam, with fast video&live-view AF and other goodies.
