One of my best sources confirmed that Sony’s priority is to launch new high quality primes for the Full Frame E-mount. That’s their focus on the lens roadmap. The source didn’t tell me what these lenses are but from other sources we heard these lenses are in development:

24mm f/1.4 GM
135mm FE GM
500mm and 600mm f/5.6
200-600mm (zoom)

I am sure there is also some more lens on the roadmap. Do you have any wishlist?

Time to make a serious recap of the reliable rumors and news we got so far:

Note:
The recently registered camera code “WW213188” is for the new Sony RX100Va. This means no new Sony camera is expected to be announced within 2-5 weeks.

Sony A7sIII:
This is the next FF E-mount camera that will be announced this year. It will have 4k 60p recording while it probably has no internal 10 bit recording (at 4k60p). I think it’s highly likely the A7sIII will have the new 5.6 million dot EVF from Sony. With a refresh rate of 240fps this simply is the ideal match for this camera. But the new EVF mass production will start in November which would mean the A7sIII would be announced at Photokina (September) or at the New York photo show (October) at earliest.
As stated recently by a Sony manager the A7sIII will keep the As7II identity (which means low Megapixel sensor with High ISO performance).

Sony A6700:
My very best source a new high-end APS-C model is scheduled to be announced this year. I guess it will be called A6700. No specs have been shared yet but we can guess it will have some of the improvements of the new A7 series like the larger Z-battery.

24mm f/1.4 GM:
A trusted source told me this lens is coming as next from Sony. No info about the announcement date. I hope it’s coming in August-September.

200-600mm FE:
I heard the 200-600mm FE is on the Sony roadmap and that it should be announced some time after the 400mm FE availability.

500mm and 600mm f/4.0 FE:
Both lenses are being developed by Sony and one of these could be announced in late 2019 at earliest.

135mm FE:
Also this lens is on Sony’s roadmap. I am not 100% sure about the aperture but it should be f/1.8.

Sigma:
Sigma 50mm f/1.4 APS-C E-mount lens to be announced before Photokina

Samyang:
One more Samyang AF lens will be announced this year

That’s all for now!

Those are the first pictures of the new Zeiss Batis 40mm f/2.0 FE lens. The lens will be announced within few days!

Zeiss 40mm Batis specs:

Distagon optical design
The shortest shooting distance is 0.24 m
With focus limiter (Full / ∞ ~ 0.4 m / 0.5 m to 0.24 m)
Filter diameter is 67 mm
Batis Size close to 85mm (40mm is slightly smaller)

I just got this from a source:

Tamron wanted Techart to produce something similar to MC-11 and it would have been branded as a Tamron product. For some reasons that I don’t know, Tamron just gave up the partnership and the whole adapter idea. However, Techart is still going to introduce it to the market later this year, with their own brand. I’m not sure how much technical support they got from Tamron.

Just my two-cent: I think Tamron should focus their resources on making new native E-mount lenses. Their 28-75mm is a real hit and also well-known photographer Albert Dros seems to like it:

The good things really outweigh the bad things for me here. I’d say that this lens is perfect for landscape photographers who value light weight and sharpness the most.

Another new review by Dustin Abbott:

And here another one by Christopher Frost:

This rumor is coming via two very old and long time rumor source. These kind of sources do write me anonymously only 2-3 times a year. They were correct 95% of the time with only one small miss in their long record. An example of their shared rumors can be read here (Sony A9, 100-400mm FE, 85mm FE, 100mm STF, 16-35mm GM, 135mm Batis)
Compared to the two sources of the wrong A7III and a7sIII launch time date these sources are of a much superior level of reliability. Still I will rate this rumor with SR4 (70% chance to be true) and not SR5 because I wanna be a bit more conservative than I have been before. SR5 rumors will be posted when I am nearly sure Sony did not spread wrong info intentionally.

Here is what they said about the new A7sIII:

Source 1 (with a track of sharing 5 correct rumors out of 6)

4K HDR 60P
The sensor is Exmor RS
The number of pixels is unknown.
Sony is nervous about information leakage, it is difficult to obtain detailed specifications.
But according to sources, the A7S III is amazing, it is really amazing.

Source 2 (with a track of sharing 4 correct rumors out of 4)

The sensor of a7sIII would be new stacked CMOS sensor with integral memory
which means a7sIII would have 4KHDR/60P.
The sensor is technically superior to a9/fs sensor.

I Thank these long time source for the diligent work. I hope he can get some detailed sensor info soon too :)

We heard from a rock solid source that Tamron will release the 28-75mm FE firmware update within hours at exactly 7am London time. It will be a typical firmware upgrade process through the camera, just like any other native lens.

This is a new roundup of nearly impossible rumors I received from unknown (and therefore unreliable) sources.

Source 1:

*there wont be any a5000 series camera anymore, the line was axed long time ago
*in aps-c world, sony thought ibis was the future, but the price skyrocket so they are considering release a version without ibis to try to get that a6000 sales numbers again, but the a6000 design its over
*the new high (above 6500) and if ever the low model, will get a new body with z battery, touchscreen, better grip and dials, more in line with new a7 bodies (say goodbye to pocket zoom, the new model will ship with 18-135, sony overpriced this lense to public, so when people look bundle it to a body they can think are getting an awsome deal, just like old a77 days)
*the a5, and i think sony its going that route, a mid range fe body, not weather sealing, smaller evf, just enough specs (like almost nothing revolutionary, old tech) the killer feature if u can call it, its the low price, aiming to be the a6000 of the fe, the one that will sell like hot cakes
*theres some a7siii prototypes, some with old sensor, one with new sensor that will had obiusly better iso, but the best thing is the global shutter along 4k120fps, new codec and only xqd card
*new info about apps/software/api
*long telephoto zoom before year end

Source 2 (rumor sent to me before NABshow):

The a7s3 will not be making its appearance at NAB. It will also not have 10 bit recording. I am also getting whispers that there will be an entirely “kind” of sensor in this camera. RGBW or organic sensor tech (not the global shutter version they just announced) is my best guess.

Most likely specs based on my conversations with my sources:

12-16mp new sensor
third generation internal processing
very high ISO (over 2 million)
fast continuous shooting
PDAF
4k 60p
1080p 120p full sensor read out
better IBIS

Source 3:

A6800 aps c camera will be announced after the rx100 mark 6.

16-50 f2.8 lens will be released with the new Sony APS-C flagship camera by the end of the year.
