In reply to:

AndroC: 18:9? I suppose there is no requirement on phone makers to reduce fractions to their simplest form as per normal maths, but surely this is just 2:1?

Actually, for TV we use HD, FHD, UHD etc.... or for USB we use USB, USB 2.0, USB 3.0.... or SD card , we have UHS 1. UHS 2, UHS 3.

For easy acceptable and understanding.

As for this 18:9.... It is not making things easier.

nametaken: If the APD element is supposed to make bokeh more pleasing in portraits, why does the lens only open to F2.8? Is it too difficult to make an APD element large enough to accommodate a wider aperture?

I think sony will release 100f2 STF and 100f1.4 STF and finally 100mf0.95 STF. Sony must sell you things progressively. lol

JOrmsby: I'm not a Sony shooter, but how many FE primes do they need in the 85-100mm range? 85 1.4, 85 1.8, 90 2.8, and 100 2.8. Meanwhile E-mount is still stuck with hardly anything, not to mention other missing FE focal lengths.

Cheers. A lot of people are seeing 2 different mounts. I see it as 2 different mounts too sometimes. sel50f1.8 vs FE55f1.8. small differences in performance but a big difference in price.

akjos: Olympus has officially lost their mind... no matter how cool and awesome the camera may be, m4/3 sensor is m4/3 sensor and will NEVER match full frame ones. $2000 price is insane when you can get awesome new in box FX D750 for example( which i own) for 200 less now...
I shot and owned just about any sensor size cameras my current kit is d750 and bunch of lenses, g7 and 5 lenses and nikon j5. Sold 2 fujis .
No matter how good the m43 camera is IQ will never equal full frame . The dynamic range and iso performance is just not there. And never will be.( physics) .
Dont get me wrong i have fun shooting with just about anything even with my j5 but olympus may have set their ambitions and prices little too high this time. Market is very competitve...
Would i like to have it? Sure... but would i sell my fx nikon and spend same money on this camera ? No freaking way.

I like the idea of FF is FF but seriously, it is not every situation that FF is better then m43 or should I say bigger sensor is better then smaller sensor. If better is better then why do you not see all PROs carrying Large Format camera?

I give you a challenge, if you use omd-em1 with adapted minolta MD 50mm f2 shooting at base ISO vs Sony A7 with adapted minolta MD 50mm f2 shooting at base ISO, having the rest being the same. OMD may not lose.

If you want to know what situation will this happens then this may be a landscape shot.

Lea5: Do people really take this DXO thingy serious?

Usually when you are lost, you will tend to put more trust on rumors. DXO has done their work to present facts and data that they have gathered. However, the person whom prepared the data may be know more then you.

I personally trust DXO and DPR very much. I am one of those people whom are "lost".

@Boomanbb, A99 will not win, but it does not means anything.

Marksphoto: so if it's equivalent to 24 mm on full frame, what does that make the f-stops equivalent to 3.5?

So back to why FF is better.
All know that FF is better.

Think about this.
With a person standing at the same place and the photographer standing at 10m away. U will need a 24mm on a FF to get the same picture (angle of view) as a 12mm on M43.

In this simlar picture taken, the FF is has a different DOF because FF is using 24mm while M43 is using 12mm.

DOF is due to the lenses difference. not because of the sensor!

Marksphoto: so if it's equivalent to 24 mm on full frame, what does that make the f-stops equivalent to 3.5?

@the decent exposure

Consider this
DOF is the distance between the nearest and the furthest objects giving a focused image.

With the same experiment, use a7 mount any lenses. place a measuring tape on the floor (example 1 metre measuring tape). Tilt downwards mounted on a tripod and just focus one point on the measuring tape (maybe at the 50cm mark). then finally take a photo with both FF and Crop mode.

U will realised that the area in focus for both the full frame and the crop is the same.

This will point out that DOF has nothing to do with the sensor size.

So DOF for a 12mm on a m43 and a 12mm on a FF is the same.

@fmian, if you know that then it is good. if the reverse happens, then apc-s will receive more light? I think you can try a simple one by shooting at a plain white wall. Anyway. I never believe too until i own the a7 and tried out this experiment.

In reply to:

CameraLabTester: This error, while they may be pooh poohed by luddites who won't be using WiFi, is a BIG lapse in QC and Advertising honesty.

Nikon users are going to be angry.

The worst is Nikon having their loyal following feeling tar and feathered.


Hi Alan, If you remote to your TV is faulty, will you consider this a QC issue?

Even if there are switches on your TV itself, I believe most of us will consider for a return.

Marksphoto: so if it's equivalent to 24 mm on full frame, what does that make the f-stops equivalent to 3.5?

We leave the maths aside. try to shoot with a FF that has a CROP mode. Mount the camera (same lenses) on a tripod and do not change any settings (ISO, aperature, focus, etc) other then FF mode and CROP mode. Then u compare the 2 photos. U will realised that the exposure is the same. Which means that this f1.4 m43 lenses is not equal to a F2.8 FF lenses.

If u r still have doubts then try a crop lenses on the FF and repeat the same experiment again. Result is the same.

Try Sony A7 with FE55F1.8 and SEL1018.

Learn that F number does not change with the sensor size.

Boss of Sony: Unfortunately, as this is not full-frame, it's not capable of taking good photos.

U r wrong. only large format takes good photo. LOL. My baby takes better photo then u, more pro then u, as she has a large format film camera in her toy box.

The comments about torturing insects are hilarious !
I guess those who made those comments never smashed a bug :-)

Hypocrisy at its paroxysm.

We do kill many insect and animals sometimes but it was never an evil intention. If you killed a frog that is poisonous, it may be still fine but if you killed a frog just for photography then it is evil.

In reply to:

forpetessake: Before people start cheering and celebrating, they need to understand that Sony (just like other manufacturers) mislead the ignorant public providing equivalent FLs and conveniently forgetting to convert the f-stops to FF as well. So they would advertise RX-10 lens as 24-200mm f/2.8 equivalent, while it's 24-200mm f/7.6 equivalent.
Same with these lens designs, they provide an equivalent FL and 'forget' to provide an equivalent f-stop.
If you look at the actual equivalent numbers, like the first design is 26-112mm f/5.1-9.0 you'll be a lot less jubilant. The lenses are quite dim, no faster than they were in the compact 35mm film cameras of yesteryear.

hi forpetessake,

They are correct about your comments. But you are correct about yourself.

Zeisschen: With the a6000 news just prior to this, it's hard to believe both product pictures are made in the same year 2014. Compared to the modern Sony design this camera just looks like a cheap plastic tool from the 90s.

to Zeisschen, 1 like for your post.

Mirrorless today is no lack of lens. There are so many adaptors to choose from. I think it is only correct to say that more than 90% of the lenses in the world will fit an mirrorless camera or E Mount Camera.
