Title: Two 200mm F2 options for mirrorless announced
Post by: Macro_Cosmos on August 19, 2025, 10:38:41
1. Sigma

This lens can be adapted to the Z-mount.

2. Laowa
Laowa flew the idea of a 200mm F2 lens with autofocus since mirrorless cameras from Canon and Nikon took off a few years ago.  It was quite exciting for me to see something finally being released.

It is nice to see them still at it with rather unique lenses instead of racing to the bottom with another F1.8 'cheaper alternative' to the big 3.

Thanks
Fascinating watching the online reviews of this.

But....bring your own biceps to help with hand holding  :P

Apparently, extra biceps to help with hand holding arent included in the extras  :P

I still like the 2.0/200VR by Nikon whicjh I already own. Nice thing about LAOWA is that the weight is significantly reduced
A Nikkor 2.0/200 with PF-construction and half the weight of the AF-S would be very tempting. The Biceps I already have

PF would not reduce the weight and size of a very wide-aperture lens that much, they can do it without PF most likely, similar to how Sony was able to make a 300/2.8 that's very lightweight or Nikon with their 400/4.5 none of which use diffractive optics.

Bokeh would be adversely affected by a PF design as well.

Canon abandoned their DO element (PF in Nikon term) from the high-end lenses, possibly because of the flare issue which is inherent and cannot be solved by the lens coating.

I guess that Sigma decided to stay away from the diffraction optics from the outset.  Apparently, both Canon and Nikon are abandoning optical designs using PF elements.

The new Sigma 200/2.0 doesn't accept TC, which may disappoint some potential buyers a bit.

I love the 4.5/400Z very much. How light weight could a 2/200 be with that kind of construction?

Nikon did make 600/6.3 and 800/6.3 with PF designs and I know many bird photographers love these lenses. Lightweight, very sharp and contrasty, but to my eye it never quite looks as natural as the conventional refractive versions.

Today it seems possible to make similar weight savings with other approaches, at least for many focal length / aperture combinations.

I think a Nikon 200/2 made with non-PF design could be of similar weight as the Sony 300/2.8 which is 1470g. I would be very happy if they do.

Oh, I missed those Z teles.  But the flare problem of PF elements seems to be more serious on faster lens like 400/2.8 which should be even more benefited otherwise.

The main reason I do not use my 2/200VR so much is the hefty weight of 3 kliogramm

The 200/2 is a small boat anchor and thus can be hand-held on occasion. The *true* boat anchor of thre Nikkors was the 300mm f/2 ED-IF; both extremely heavy > 7kg, and with a fat and short barrel that made carrying it slung over your shoulder meant you had bruices all over as the massive piece of metal rolled around.

The 300/2 Nikkor was the first - and only -- lens I have sold because I couldn't manage it in the field.

Thank you to Birna, and others.
This has sent me down a wonderful rabbit hole (http://www.company7.com/library/nikon/Nikon_0300f2.html)

Back to the 200mm focal length, did any of you ever get to play with Canon's f1.8 version?

A colleague had the Canon 200/1.8. White, heavy, sharp, and didn't fit my Nikons :)

I did keep the special TC 14C bundled with the 300/2, though. It worked well on my 200/2 ED-IF and the 500/4 P.

I have some information on the 200mm F2 from Laowa.  Take this as a 'rumour', I guess.  The source is "trust me bro".
- 43mm drop-in filters with gear that allows adjustments for VND, PL and CPL.
- At least for the z-mount version, plan is to support teleconverters.  I whined about Nikon's engineering of these here: https://nikongear.net/revival/index.php?topic=11298.0
I have conveyed this to VO and they said they will get a copy of these TCs to ensure mechanical compatibility.
- With the TC, filters cannot be used.
- Canon EF mount offered which allows AF on Canon DSLRs, and can be adapted to Canon's mirrorless mount -- a way to circumvent patents/licensing?
- This means the lens was likely designed for DSLRs.  Mirrorless gets the benefit of using internal filters.
- Price: it will be cheaper than Sigma, quite a bit cheaper.  Due to the tariffs stuff that can change any time, I do not think I am comfortable in disclosing it.
- Image quality is at least as good as Sigma's.

Wait until October.

The Nikon AFS versions of 200mm f/2 are really nice performers, have shot some amazing images with them  8)
