Aww... ...shucks...
My two LEAST favorite focal lengths. Quite a disappointment - more waiting.
I am sure this will please some (for good reasons) but I think we can all agree that what Sony does not even offer is a great wide angle prime lens. This is the void to fill.
Anything at 28 - or wider - would have hit the spot for me.
A 25/2, a 24/2 would be perfect. I would be ok with f2.8.
OR a very small and capable 28/2.8 and a stellar 21/2.8.
The 18/4 from the ZM line transgendered into FE mount too, while they are at it.
With my usual "luck" I am sure the next one will be a 85mm. ...Show more →
I would not mind a good 85, but I am with you on the 28/24, even if I would be pleased with a 2.8, no need for me to go faster. Still. I think my D28 and the G90 will survive another year on my A7.

Said another way the biogons don't have an exit pupil that is far enough away from the sensor, or so it is thought. Could they make one with an exit pupil further away? I don't know, but that might be hard.
My understanding is that it's a requirement of the Biogon design, and any other symmetrical or semi-symmetrical design. I suppose you could have a Biogon with a longer distance from the sensor, but only at longer focal lengths, where the design would make less sense for other reasons.
Anyone know how the 50mm+ Biogons for MF and LF cameras perform on the A7?

for me it would still be a better bet than a typical AF oem lens in this respect. i don't really expect any of them to still be functional on new cameras in 10 years. this at least will still work fine on the a7 in 10 years. if sony abandons FE mount i can get backup cameras to last that long cheap. honestly though, zeiss has a relationship with sony that probably gives them a pretty good idea what is in the pipeline. the fact that they are(?) building a bunch of lenses around this mount independent of sony suggests they feel sony has a real commitment to it.

As Sebboh points out Zeiss probably has the inside to know where Sony is headed. Perhaps they chose to do the 35mm & 50mm now because they have insight into when Sony will improve design to better accommodate wide angle lenses.
Hopefully the next couple of Loxia lenses will be one on the long end (like an 85mm) and one on the short end (like a 18 or 21mm) and then fill in a few more in between later on.
A great 3 lens set for the A7r would be 18mm, 35mm, & 85mm - I have wider and longer covered with my legacy glass.

Here is the Zeiss PDF on Zeiss lens names and how they relate to entrance/ exist pupil - as well as the requirments for digital wide angle lenses.
I think it is a little strange that they are not releasing a wide angle (wider than 35) early on. They seem to be tuning in a little to feedback and the wide angle void is obvious.
Perhaps the sensor/mount is not that easy to cater to and perhaps churning out a decent wide angle isn't all that easy. Surely there is one or two in the works.

I would assume they are releasing the lenses that are the easiest to make, least expensive, and likely most popular first to test the waters with the FE mount. If these sell well I imagine longer and wider will come . . . one can hope at least.
Longer is not really a huge problem (for me) due to reasonable legacy glass, but as we all know wider is problematic with legacy glass - so I'd prefer wider lenses to come first.

A decent wide angle shouldn't be that hard... but a compact decent wide angle might be. :/
A compact wide angle WILL be not easy, depending on how compact is it, how wide it is, and how fast it is. I'd settle for a 18 or 20mm f/4 . . . how hard could it be
I assume that at some point Sony will introduce IBIS into the AX line which will compensate for the lack of faster lenses for some people in some situations.
Ehrm, 35 and 50.. What an internal stunt they must have done to avoid 28 or 21 or even something longer than 50/55 when they just co-branded the only primes available at 35/55 (with the latter excellent, and faster too).

What you have added isn't logic, but an emotional attachment to maximising profits. My post was logical. Lots of people get upset when they feel used, which isn't healthy for a company in the long run.

Of course if you can build a 'wow' brand where people buy based on fashion rather than details you can milk all you want. Anything from clothing to iphones to cameras.

Hey, on the 35 you gain 1 stop and hopefully much better IQ than the FE 35/2.8 (that's what it needs to deliver anyway to be relevent for most).
I am hoping that this lens won't be too expensive. I like the FE, but to be honest, I barely use it. Too slow, too little depth of field control.
I might well get the 35/2, depending on rendering, but the only way I would even consider the 50/2 is if it has an aperture ring...

Maybe they don't want to fully reveal their cards yet.

Announced over the next 12 months. Wish it was sooner than that, hope they're announcing a UWA as one of the first ones. There already is a good 50mm equivalent.
Beni,
The Samyang 14mm f/2.8 is fabulous on the A7r. I have one in Pentax K-mount (meaning I can use it on the K-3 too) and attach to the A7r via either a Novoflex or Rayqual adapter without issue.

I've already wasted too much time on this incoherent conversation. Clearly, you have both the time and expertise to comment on every single post on this forum.

Dude...if us regulars here weren't experts on everything, and didn't comment on every single post, how would we get post counts in the thousands ?

Indeed if Sony sticks to the current configuration of sensor toppings it's like they're shooting themselves in the foot. They need to remove that AA filter and minimize the glass thickness as much as possible.
Ed:
I do miss the Leica RF wides and the ZM's - i.e. their performance on RF.
But, there is always hope for an A9r.
False hope is better than no hope at all.
I look forward to the A10, nicknamed the Warthog, it ought to be tough enough. Lenses will be fly by wire though.

i agree about them using cosina. really hope they don't base any new 50s on the zm or ZF 50/2. i don't really like the look of either of those...
The 50MPZE use to be my favourite lens for a LONG TIME. It's pretty fantastic with everything but bokeh (at times). The colours and the way portraits pop are amazing. After using Leica M however, I'm really not that interested in Zeiss anymore. I find that the 50APO cures all of my lust for a 50mm lens. Wish Leica would make AF M lenses for a AF FF M body
