Yes, Lloyd was replying to me. Unfortunately, his reply was quite useless due to his frankly silly attitude toward adapting lenses - of which he has examples posted that he himself has shot in the past. I can't disagree more strongly - I use mostly adapted lenses on all of my Sony bodies, many being large and heavy (Otus 55/85, 35/1.4 Milvus, 135 ZE, etc) and obtain perfect results. I use a Metabones adapter that mounts on a RRS L-bracket, as rvh23 has described. It holds the weight, keeping stress from the camera mount. And the idea of swinging the camera around with a heavy lens is unrealistic, at least for me; I don't mount the lens until it's ready to put on the tripod.
I nearly sent back these same comments to him, but in the end, I decided "why bother" - as most here are aware, he thinks he's always right, and I have no interest in arguing with him. I could also point out that Rich Schleuning from Zeiss also shoots all of his Milvus and ZE/ZF mount lenses on Sony with an adapter, and these are the photos that he's posting as examples of these particular lenses! I think that says a lot right there.
Anyway, since that time I've decided to go ahead and get the Loxia. However, there's every chance that I'll also still want to get the Milvus at some point.

Of note they Sony mount has been also beefed up instead of 4 screws I think it’s 6 now. The only body that was problematic was the A7r since they used plastic under the metal mount. I replaced mine with a tough mount at the time. Never had any issues with later bodies. I can add a lot about Mr. Chambers but smarter of me not to do so. I think most understand where I come from on that.

Personally I got tired of adapting lenses but that does not mean for 1 second that it is a bad move at all. More personal preference and I do like having the Exif data. My bet the Milvas lenses still give you that with a Metabones. Have not tried one myself
But having said that I have a really good feeling on this Loxia 25 so I ordered one also. Last lens too fill out a perfect kit. I maybe there folks. Lol
Here is where I’m at now. I’ve been through many
Laowa 15
Firin 20 just bought it again in MF
Loxia 25
CV 40 1.2 E Mount
Loxia 85
Batis 135
Sony 24-105
I will get the A7III at some point
I’m down to 2 bags PD 5 and 10. One Think Tank roller
Lighting
Flashpoint Explor 600
3 Flashpoint AD 200
1 Flashpoint 860
1 mini 350
Pro trigger and 1 older backup.
I’m feeling really complete here. I need something I’ll rent it
BTW need to look into the Nisi V5 filter system . I just bought that but I bought Breakthrough filters instead as I know they are very color neutral. Really cool kit

Yes, Lloyd hasn't thought through adapted lenses very well. If you adapt lens often as I do as well, you have to be thoughtful about it. First, if you adapt a big lens and you are using a tripod you want to have good support for the lens. Danny's, solution for this of getting an adapter with a tripod mount is a good one. Personally, I have a rig with support a little further down the lens. I mount the camera on a 15mm rod system which is then mounted to the tripod. Then I add a lens support that moves up and down the rods and can be adjusted in height that provides good support for the lens. It is great for support for long lenses as well. Novoflex also has s system that allows you to mount their adapter an a tripod foot that then allows you to change the orientation of the camera. All three are good ways to go depending on what you need. Second, you have to be prepared to shim your adapter is you are not getting optimal performance. I don't think adapters (even the best ones) have nearly the tolerances of camera mounts, so you have to be willing to address that which means you may need to modify your adapter or buy several to get one that doesn't tilt the lens. Third, as Danny suggests you should be careful to mount your lenses only when you need it and to support heavy lenses with your off hand if you shoot handheld. That really isn't different with native mount lenses, but may be more important with adapted lenses.
I can certainly see why people may not want to fuss with adapted lenses, but there is no inherent reason they can't work if you put in a bit more effort.

Guy - for "normal" shooting I have an A7RII and III, but I do have an A7R that's converted to infrared. No problem using it with the same adapter setup (with RRS L-bracket), but I'm aware that the mount is less well built than the later models. The situation where I have to be careful on the A7R is shutter vibration. Normally it's not a problem (the adapter/bracket and a good tripod eliminate most of it), but sometimes it's an issue with long lenses and a high or very slow shutter speed is needed.
I remember that you don't care for adapting lenses yourself, and I can't disagree with your preferences on that. Personally, I don't mind at all - I do it so much that it's second nature - and I'd never give up my Oti and other "special" lenses that don't come in E-mount. That said, it's a pain to keep switching between adapted and non-adapted lenses, so I tend to take all of one type in the bag at one time, except that I might take one with the adapter already mounted when I'm using all E-mount otherwise.
Yes, you do get full EXIF with Milvus and also with ZE lenses as long as you're using a Metabones or Sigma adapter. Nice.

Steve - that's interesting re: your support system. It would be fun to see a photo sometime. It sounds similar to the setup that I had with my Fuji GX680iii. That whole system is an absolute beast - too heavy to use outside unless you're very close to the car - but I loved it and only sold it 3 years ago when I converted to digital.
I had their 500/8 lens, which is small for a 500, but still a good-sized lens. It was sold with a metal rail about 18-20" long, plus a metal collar to place around the front of the lens. The collar included small wheels to roll along the rail! An attention-getting and cumbersome setup to be sure. I'm surprised I didn't lose it one time when I was shooting water lilies over an artificial pond at a botanical garden. I didn't have the lens latched into place properly, but somehow I noticed it before the whole thing fell into the pond...

Yes kind of why I went all native E Mount was the back and forth , totally agree it got on my nerves. But nothing wrong with it and I’m under the gun a lot so it makes sense for me. You can switch the A7r Mount if you want. My issue was I wore it out, the plastic underneath was detoriating so at some point you may see that.

I never really considered acquiring the Loxia 25, I already have the Loxia 21 as well as the Zeiss ZM 25 but with all the preliminary reports coming in I may jump on this one as a potential replacement for my ZM25 which I currently use with a OptoSigma front filter. Would be interesting to see the difference between the two, the ZM is such a small sharp optic.

Boris, a tape measure is perfectly adequate to measure your angle of view with reasonable precision. Use the distance to your camera sensor (shown on the outside of the camera) and subtract about 6.5cm, which is the entrance pupil distance from the sensor for the Loxia 25.
If the Zeiss data sheets are accurate, the specified angle of view corresponds to a focal length of about 25.3mm for the Loxia 25. For the Milvus 25, the data sheets were in very good agreement with my own FOV measurements, and both indicated a focal length of almost exactly 25mm,
By using this method with a tape measure and a subject/focus distance of about 1.5m I calculate a focal length for the Loxia 25 of 25.6mm. No idea how accurate this is.

I believe the diagonal angle of view is measured by the manufacturer at infinity distance.
BTW: Zeiss lists the Batis 25/2 with 82 degrees and the Loxia 25/2.4 at 81 which is the same as ZE/ZF and Milvus.
That could be after distortion correction (which I'm sure is higher for the Batis)
Usually a 24mm lens is 84 degrees AOV which is noticeably wider.

I doubt it breathes much (video lens), and thanks for the FL info. Distortion correction will be minimal impact in the L25, you would expect, at just 1.3% optical quite straight barrel.
CZ don't publish native distortion for the Batis 25mm, but Lloyd to the rescue! It's 1.6% in the usual Distagon wave form with kick up. [soon it will all be baked in, probably, as it becomes more embarrassing what they are doing.]

Loxia lenses are definitely 'breathers', even thought they are targeted for video work.
I'm intrigued by the Lox 25 even though I'm well served by the wider 21mm. My next focal length is 40mm so I'm hoping the 25/2.4 will be put to good use.

How do you like your Milvus 35 1.4? I heard great things about it.
I do have a walk about set that I like (Loxia 21 mm, Zeiss 35 mm 1.4 ZM, Zeiss 50 mm 1.5 C Sonnar and the Sony 85 mm 1.8).
If the Milvus 35 mm is compelling enough, I will sell my Zeiss 35 mm 1.4 ZM to fund it. I do have the Sony Zeiss FE 35 mm 2.8 that Would compliment my light set.
