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

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

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

the MTF of new FE 2470GM/70200GM is way too amazing, oh the later actual test shoots can match the curve

Couscousdelight: Pentax is a dedicated photo company, they think about lenses before they release a body.

Sony is... something else.

I remember 24-70/2.8ZA started to sell from Feb in 2008, since a900 announced in Sep, 2008.
