Moon0326: Who's gonna use 14mm f/1.8? For astro, you can just buy 20mm or 24mm then stitch. Those two focal length with the same F or faster (1.4) absorbs much much more light (at least 3x). I expected 14mm f/1.8 to be cheaper. At this price range, I don't really see a reason to buy one.

"absorbs much much more light (at least 3x)."

How did you make this calculation ?!?!?!
The difference between f1.4 and f1.8 is 2/3 of a stop (0.66), so 66% more light.

3x MORE would be +300% ! So 4X the original EV value.

On article Sony FE 100-400mm F4.5-5.6 GM sample gallery (101 comments in total)
In reply to:

deep7: Thanks for the gallery. The lens looks pretty good. Is it my imagination, or have Sony worked very hard to make it work better at the long end (a bit like the old Olympus 18-180 and unlike most zooms)?

These samples also show how much cleaner the A9 is than the A7r2. Interesting.

I do wish you people would learn to use the aperture control on your cameras...

If you would mix A9 pictures and A7R2 pictures downsized to 24 MP,
without EXIF you wouldn't be able to tell which is which...

In reply to:

samhain: If the old saying "lenses are the heart of a camera system" is true, then it's pretty easy to see why Nikon is flailing while Sony is creeping into the #2 position.

Nikon makes great bodies, but the only lens from Nikon in the past 10 years that's been even remotely appealing to me is the 58mm, and sadly that one didn't live up to expectations.

I was shocked to see that Nikon does not offer a 16-35 f/2.8 !

In reply to:

john: I found this long ago when testing the NEX-5N burst mode picture ISO noises. The burst pictures are always noisier than the single shot pictures with exactly the same settings. At that time many people did not understand the reason behind it.

Well among other reasons, when electronics heat there is worse S/N ratio.

kinglau711: Sony lenses with their weak plastic junk mount are worth nothing compared to Fuji / Canon / Nikon.

What kind of insecurities do you have ? To need to troll...

In reply to:

whyamihere: The first two thoughts that immediately jumped to mind:

1. This is, to me, the more interesting of the two lenses announced today.

2. I can only imagine how much the lens is depending on the camera for image correction. The Sigma and Canon equivalents are big and have huge, bulbous front elements in order to produce the flattest image possible at the wide end. I can't imagine this lens producing the same level of image quality across the frame as its competitors, meaning there will probably be some optical compromise (distortion, vignetting?) that the camera will try to correct. Of course, that's always the price you pay for a more compact lens.

Well it's maybe easier to make a wide angle lens for a mirrorless camera, optical formulas may be intricate for DSLRs.

Benjosh: I don't quite understand the price difference of 4500USD vs 5300Euros...
But i have to admit that this new series is a great achievement, however a bit heavy on the price, will stick to my trusty ILCE-7M2 until the R-Type drops.
Speaking of Alpha 9, if there would be a different medium, other than SDXC that could save uncompressed RAW files of 42MP quickly enough then there would be room for improvement for a 9R series.
After calculating 82MB/uncompressed*20Shots/s=1.6GB
Since the Alpha 9 has the same 24 MP as the 7II it would require 60MP*20Shots/s=1.2GB write speeds
That would require a build in, m2 solid state drive, which would even allow 42MP in uncompressed RAW to be shot in sequence (20Shots/s).
Gosh im drifting away here... would be awesome though.
Anyways im exited.

Even with VAT it shouldn't be so expensive !

larry angier: Psst! I don't mean to rain on Sony's parade, BUT...the emperor has no cloths, I mean glass! Where's the long and fast "sports/wildlife" lenses that C&N both have, I mean, the 200/2, 300/2.8, 400/2.8, 500/4, 600/4, 800/5.6, 200-400/4... that a sports & wildlife shooters use all the time? Instead there seems to be just another 70-200/2.8 and "announced" 100-400/4.5~5.6... Come now, you gotta have the exotic glass to make this a real game changer.

One step at a time.
Just look how many great lenses arrived on E mount in the last 3 years... Canikon took many more years to reach that point, Full frame E mount is still recent.

The GM1 is great in its own category, but you compare apples to oranges there...

wlad: RJ45 ??? what the hell for ? wireless can go up to a couple of hundred of Mbps, why wired ? Is this supposed to stream the video directly ?

Hmmm what a "sweet" person you are wlad...
Yes you were correct in writing Mb, but people forget that MB are actually 10 times slower (8 bits + 2 bits for parity check).
