On article Sony a9 Full Review: Mirrorless Redefined (2671 comments in total)
In reply to:

Hibiscusbloom: The no blackout is amazing but i didn't feel that the AF acquisition on the 100-400G with the a9 was any faster than the Canon 100-400 II on the 1 DX or 7D2. That's my feeling after trying it at the shop. I don't know about tracking as I wasn't able to in that short 10-minute trial with scores of others waiting. Please correct me if I was very wrong. Much appreciated.

looks like in day light, AF speed of 1dX2/D5/A9 are very close, but in low light, a9 might be faster...

In reply to:

paolo260252: For about 40 years I've been using Nikon in my work as a photographer. In recent times I started using Canon because some lenses are better especially those that allow shifting, the so-called PC. In my opinion a body must be heavy enough to dampen the vibration and big enough to be easily grasped. The A9 is too small and too light for a photographer, whether it's a man or a woman. Performance and speed are important but not all. The pentaprism offers a realistic view and not an electronic translation of the scene. When you frame with a mirror less the scene looks like an imperfect TV screen. Will the future of cameras be mirror less? I tried Hasselblad and Fuji and the file is not at all better than the one of a D3X or a 5DS. In addition, they have the problem of battery life and sensor warming up. So why this enthusiasm? Sometimes I would like to speak with some of the engineers and technicians of Nikon and Canon just to tell them what a photographer really needs from a company.

I would say put the battery grip on it, perfect size with light weight(relatively).
currently SONY newly developed lens are great (design), pick up a good copy.

not sure, but from the studio shots, ISO100 is "a lot" worse than a7m2: less sharp

1Dx4me: sony photog products while sound good on paper, they still need to be tested and recognized by the pros! i am positive that canon lenses will come ahead all around if tested side by side when sony lenses! sony is relatively a new comer in optics. i think sony needs to do something about those high price to make them more appealing and reachable to masses, IMHO! good luck.

maybe depends, looks like "only" 35/1.4 L2 has better CA control (due to BR lens?).
but maybe Sony really needs to improve lens quality control for better consistence

On article Updated: Sony a9 samples with Raw support (450 comments in total)

looks like processed style is more pink/blue -tone. more canon style.
maybe WB-adjustment + some DRO1/2, can perfectly help, for OOC JPG.
and AWB preference can also be set since a6500/a99m2 & a9. It's not a big deal for me.

what's more important to RAW IQ, could be ISO performance between 3200~12800, comparing to 7R2.

Bombastic: I'm sure Sony will eventually come up with a 300/2.8... Given their product cycles, the A12ii might out by then, but I'm sure they'll make it.

What concerns me however, are the ergos. How easy are these to hold? I rented the A7r and A7rii, and they were never as comfortable (I'm not even suggesting balanced) after a couple of hours into my day.

I would say 1st to come up long prime would be 400mm, as there is 300/2.8 & 500/4 in a-mount .
it's rumored there is a FE 400/4 under development...

In reply to:

livelong: I really like this new out of focus bokeh. Once again Sony catches Nikon and Canon off guard.

check out the real-world shots, NIKON'S DC is too old maybe, the boken is far inferior than M 135/2.8 STF...
but i do hope sony will soon bring out a 135/2 STF GM OSS with faster T value(T3.2 OR T2.8), don't mind it's bigger/heavier

TristanW: well, look at real-world shot comparison, sigma art has sharper left-corners, while GM has a bit better consistency, especially in overall right side(F1.4~5.6)

85GM

In reply to:

dkyl: The 100mm 2.8 STF looks interesting. There's a Laowa 105mm f2 STF that seem to perform pretty well but is manual focus and lacks stabilisation although depending on the body you might get back some form of stabilisation.

Laowa 105mm f2 STF 's boken is way worse than 135/2.8 STF, especially during night shots

Sigma 85/1.4 is way too big/heavy, I would vote 85/1.4GM

In reply to:

rz350: And it is only $200 more than the Sony 70-200! That is impressive for pricing, considering that the Sony has to rely on the camera body for stabilization. I must admit that I thought Sony lenses were expensive to state the obvious, but Nikon is setting new standards.

sony 70200GM has on-lens OSS, plus IBIS for rest 3-axis compensation

In reply to:

Nobby2016: what about the aperture closing down for fast shooting?

i read for 12 FPS you basically shot at f9.. is that true or did someone tell me BS?

my understanding :

with hybrid AF, apture can down to F8
rest AF, aperure need to be open to F3.5 or wider( f2.8 , f2 ...)

Sid911: How much does the 70-300 for Sony E mount costs?

come on, there is only 1 special element here. check out FE 70300G 's construction, how many special glass there.

Totally different positioning & performance

DamianFI: I thought it might make my GM lenses focus a little faster, but can't see any difference.

They aren't bad, would like the 85GM to be a little snappier like my 1.4/85G Nikkor.

sorry, i don't agree again. 85GM has much sharper and better blur for N85/1.4G

N's recent good blur-lens is 58G, with trading off the sharpness.

snappier would trade for worse sharpness or blur

In reply to:

lecoupdejarnac: If you look at most of Sony's native FE lenses, they have a deep 'air gap' between the rear element and the mount that increases the registration distance. So most seem to be variations on old reflex designs, not new designs for short flange-back cameras. Smaller lenses may come in time, as companies start engineering for the small flange-back distance specifically. A few have appeared already it seems (loxia etc).

definitely not! expecially new lense in rencent release

In reply to:

noflashplease: Sony's slow 70-300mm is $1,200 and has a 72mm filter thread? It goes to show that mirrorless lenses aren't necessarily smaller or cheaper? Unless this lens is as rugged as the Canon L-series, it's over priced by 50%, perhaps more if compared to the excellent Tamron 70-300 VC. I would hope, and even assume, that Sony's new "Nifty Fifty" is superior to Canon's recent 50mm F/1.8 STM, but it's also twice the price. Do you see a pattern here?

With the new adapter, I wouldn't be a bit surprised if Sigma ends up selling more FE lenses than Sony.

come on, it targets against 70300L, which is expensive as well
