Just as promised.. A few mundane samples from me.. But maybe it's visible what I see in that lens.

while the GM isnt as strong with regard to sharpness, if you shoot into bright sources of light, flare can be a real issue with the 100-300. both 70-200 and 70-300 are flare resistant, I'de believe the 100-400 would be as well.

havent tried the hood since its so big

I have the original hood for it. It's all metal but not reversible since it's a screw-on type.
It does make a difference though.


Great samples Ronny and Jannik!

Thanks for the hint, Charlie! Havent put the Contax 100-300 into a flare stress test so far. My Contax 100 is a marvel in that regard.

Thank you, Fred. I have the hood as well but it is pretty huge and unpractical. Didn't use it once so far.

Same here. Just to have something, I just ordered this one to try:

Thanks Fred - The good news is if you know you are just shooting landscape you can take the 100-300. If you have a mix, then you can take the 100-400!

Thanks, Fred! I keep that in mind if I encounter any issues. I'm a non-believer when it comes to lens hoods, at least in most cases.

Chris, that boils it down to the minimum.. I am not sure in what camp I am.. At least I'm currently not in the three grand camp :P

Definitely not the best choice for 'action' but when you hit focus, colors and micro-contrast are hard to beat.





  ILCE-7RM2    ---- lens    1/500s    100 ISO    +0.7 EV  






  ILCE-7RM2    ---- lens    1/1000s    100 ISO    +0.7 EV

Fred - absolutely no surprise for me. The CYZ 100-300 VS is just an amazing lens for landscape and static subjects, especially at the 100-200 range. It was a solid winner in my tests against the Canon 100-400, Leica 70-210, CYZ 80-200 and the CV 180 APO Lanthar. Only my CV 90mm f/3.5 APO Lanthar LTM came close to its sharpness and microcontrast.

I expect intended application drove it's design. Meaning that for Zeiss there would be greater demand at the 100-200 FL as opposed to the 200-300 range so if there had to be optimization it would be at the 100-200 range. As for an AF image stabilized 100-400 zoom, most people would be at the long end trying to shoot birds and other wildlife.

All that to say I am not even tempted to replace my CYZ 100-300 with the Sony 100-400 for landscapes.

For wildlife photography I had hope to get a Sony 100-400 but gave up and went with the Fuji 100-400 and its matched 1.4 TC. With the 1.5 Fuji crop factor it's a brilliant set up! What really really surprised me was Fuji's claimed 5-stop image stabilization performance. Even at the crop factored 853mm FL I am not tempted to mount this on a tripod. It's just that good!

I have that hood for my CYZ 100-300. Does a great job, collapses with no problem and allows filters to be screwed on it.

I think contax hoods are in general built to be as effective as possible (modulo some hood sharing in the system) at the expense of practicality.

I have the original hood for the 3.5/100: it's HUGE

Surely the OSS of the 100mm-400mm is a greater advantage than the Zeiss sharpness at 200mm no? Real potential to leave the tripod at home if you can get 3-4 stops out of the OSS.

I've seen mentioned that this lens' OSS is capable of 5-stops but can't find this info in any official Sony page. Even if it's true, it won't be for all focal lengths. With the Zeiss 100-300, you can still manually choose the FL for IBIS. I have not tested if the stabilization between these two lenses is comparable.

So you plan to test the stabilizer? Maybe you can also have a look at this issue: My G 4/70-200 is well centered but when using OSS I regularly have a sharp center but one unsharp corners or side. I know this issue happens with other lenses as well but with the G 70-200 it happens much more often to me. So I am curious if it happens with the GM 100-400 as well.

I'll test it out and let you know.

Yeah, I could see 5 stops based on the OSS systems they've used in other lenses, but that would likely only be at 400mm and probably only about 1 out of 10 handheld shots. I would expect around 2/3 stop advantage at 100mm and 1 2/3 stop advantage of the OSS over the IBIS. I just pulled that out of my butt based on my previous experiences, and I wouldn't be to surprised if there was indeed an occasional blurry edge due to the OSS.

-Edited for screw up.

Many thanks for your review Fred!
I have the C/Y 100-300 and thankfully my wallet is safe now :-)

With high res bodies like the A7RII, I consider the shutter speed rule of thumb for handholding (without OSS) to be focal length times 2. So, at 400mm, I would consider handholding it at 1/800s as a minimum.

With OSS activated and with good technique, I'm able to handhold it with great results at 400mm + 1/50s, which is 4 stops from 1/800s.

That's interesting. I find it really varies. Especially with moving subjects shooting hand held with a high res sensor it can be even worse. For example, with my Batis 85 I need 1/400 to get consistently sharp images with OSS/IBIS enabled doing candid street. However with good sniper like breathing technique I can shoot static subjects at 1/30 with the FE 55.

I'm sure it depends on your body and how drunk or cafinated you are. Intoxication probably offers an extra stop of stabilization. A triple espresso the opposite.

I was referring to camera/lens shake and not subject movement though.
