p.1 #1 · Does Nikon have answer to Sony’s extreme aspherical element?


Inspired by this post, https://www.fredmiranda.com/forum/topic/1915421/1, it seems like some folks suggest Sony’s extreme aspherical element is the reason why Sony is able to make such lightweight lenses - I’m thinking of the 300 GM. Is this true? Does Nikon have any similar technology (disregarding PF)?

Just compare the new Nikon 24-70mm f2.8 mk II to the new Sony 24-70mm f2.8 mk II... the Nikon is lighter despite featuring an intrinsically bulkier fixed zoom design essential for video work and has 14 elements only vs 20 on this Sony.

The current master of lens design and production is Nikon.

Nikon has not yet released their Z mount lens covering 300mm f2.8 but odds are they will go for a much more flexible 100-300mm f2.8 rather than a fixed 300mm f2.8. And I would totally support such a decision. A fixed 300mm f2.8 is super niche in 2026, just like nobody uses anymore fixed 200mm f2.8 since 70-200mm f2.8 lenses have started to dominate 20 years ago.

Cheers,
Bernard

If anything, it’s Sigma not Sony that offers the lightest f/1.2 lenses on the market. Sigma makes the lightest 50mm f/1.2 with AF, as well as the lightest 35mm f/1.2 with AF. Sigma’s 85mm f/1.4 is also lighter than equivalent lenses from Sony and Canon. Even in super-telephoto territory, Sigma’s 500mm is about 100g lighter than Nikon’s 500mm PF. The same holds true at 200mm f/2.

In other words, it’s “Bigma” that delivers the lightest lenses across many focal lengths not Sony.

Sigma has also produced the world’s first 135mm f/1.4 autofocus lens and a 20–200mm 10× zoom. The Sigma 300–600mm is another crown achievement.

I doubt that Sony has access to very much that Nikon and Canon don't have. Whether Nikon or others chose to implement various technologies is another issue. The 400/4.5 uses a conventional design (not PF) yet only weighs about 1.2kg, so presumably Nikon could make a relativley lightweight 300/2.8 without any special tech they don't have access to already. However, it's more likely Nikon will make a versatile 100-300/2.8 pro type of lens like Canon has. The zoom is more practical for sport and events.

This strange idea of people that one optical company has a decisive advantage over other optical companies just because they have technology X is really, well, I already said strange.

If Nikon has shown one thing recently is that they can build lightweight lenses. In fact, personally I would prefer if they would stop. Or make two families of lenses, one well built and one super light weight. You get three guesses which one I would pick.

Honestly I wouldnt want a lens using what you describe anyway. It basically turns a telephoto lens, the most easiest to make lens (because they dont have to bent the light much), into a wide angle lens, the hardest lens to make.

It’s good that you bring up the 400 f4.5….

maybe I should have prefaced by saying to the quality of the exotics primes, because even though the 400 f4.5 is light weight, its sharpness is not on par with the 400/600 TC nor the 600 PF.

Could the extreme aspherical element be the secret source that enables Sony’s 300 GM? Even though it hasn’t been out for long, I think many would agree this lens would become one of the best wildlife lenses of all time for how light and shape it is…

Light weight super telephoto lenses are anything but niche. Premium super telephoto has a big market for hobbiests - see 500/600 PF. I have seen so many anecdotes of people switching from 600 f4 to the 300 GM just for the weight savings (with minimal loss in sharpness). That lens will come down to be one of the wildlife lenses of all time.

The Z 120-300 if made with refractive optics would be at least twice the weight of the 300mm GM. If made with PF, it would have other compromises. Its use case will be vastly difference from 300 f2.8 and doesn’t serve the same purpose.

70-200 f2.8 is not the reason why camera companies don’t make 200mm f2 anymore. By your logic, no one would be making a 135mm f2. 200mm focal length doesn’t have great uses - too long for portrait and too short for wildlife.

Good point about the Z 24-70 f2.8 ii. Although I wonder if the advantage of the aspherical element lies in correcting annotations for longer lenses

To be clear, Bernard referenced 200mm f/2.8 lenses (not 200mm f/2 lenses) as having been replaced by 70-200mm f/2.8 zooms. Which is true. Nikon never updated their 180mm f/2.8D with an AF-S/G/E model. The Canon 200mm f/2.8L II was released in 1996. There have been numerous 70-200 zooms since then and the industry trend has been to make them smaller and lighter.

“Extreme Aspherical” just sounds like a made up marketing jingle. Probably no different than the asphericals from X, Y or Z manufacturer.

Everyone has been getting better at making aspherical elements and putting them to use, especially with some of the more recent “molded” lenses. Grinding them well was very hard in the past.

The use of asphericals should allow for the corrections to be made with fewer elements which would allow an equivalent design (correcting the same number of things) to be made lighter.

There are a lot of tradeoffs balanced when making a lens. More technically perfect (heavier), Less vignetting (heavier), Doesn’t require extensive in camera distortion profile corrections (heavier), etc.

The 400/4.5 is also much less expensive than the 600 PF, 400/2.8 TC or Sony 300/2.8.

Nikon didn't use fluorite elements in the 400/4.5 which may be why it is so much cheaper and why it is not quite as sharp at f/4.5 as the 400/2.8 at the same aperture. But IMO is it is perfectly fine and its light weight and beautiful images make it a pleasure to use. Since fluorite elements are time-consuming to grow, it is perfectly sensible that they used Super ED and ED elements instead in this lens that costs a fraction of the 400/2.8 TC.

Which brings us to a crucial point.
There are far too many factors involved in the design of a lens to focus on individual factors like specific lens elements.

It starts with the fact that the Sony FE mount has a significantly smaller diameter, and as far as I know, was initially designed as an APS-C mount.
Add to that the differences in design philosophy, which in turn correlate with the characteristics, limitations, and possibilities of each mount.
In my opinion, Nikon places greater emphasis on the optical correction of various aberrations, while Sony relies more on digital corrections.
For example, focus breathing is primarily corrected optically by Nikon, while, to my knowledge, it's corrected digitally by Sony.

Then the portfolios differed noticeably, which is partly correlated with the lens mounts.
Nikon primarily pushes the boundaries of lens design with its f/1.2 S lenses, the Plena with its oversized rear element and new standards in optical vignetting, or with feasibility studies like the Z 58/0.95 Noct, taking advantage of the large Z-mount.
This logically leads to larger, more extreme, and more exotic lenses.

Which brings us back to the design philosophy of such lenses.
What compromises am I willing to make as a lens designer/manufacturer, and to what extent?
Do I take the middle path, striving for a good balance between optical performance, speed, dimensions, weight, and price, or do I want to push the limits and thereby neglect factors like size, weight, dimensions, and price in favor of more extreme optics,

Nikon has recently demonstrated its ability to set new standards with the Z 24-70/2.8 S II, which is significantly lighter and has fewer optical elements.
Lense lenses like the Z 400/4.5 VR S, Z 600/6.3 PF VR S, Z 800/6.3 PF VR S, as well as the Z 400/2.8 TC VR S and Z 600/4 TC VR S, are also highly optimized for weight.
However, this doesn't seem to be the primary focus.
The Z-mount offers new possibilities and approaches for Nikon lens designers, and it makes sense to utilize them.

Not to take anything away from any companies, but I have to wonder if the real driving force behind the rise of significant advances in optical design are the companies making optical design software, that most optics companies are probably using at this point. You can still see differences between companies optical philosophies in how they optimize their designs, but across the board lenses have greatly improved optically in the last decade.

For example Sony seams to be willing to rely more on software corrections and allow high levels of vignetting to make smaller and lighter lenses than Nikon, but both are making very sharp lenses with very good AF performance.

Hard to see any 300mm ever become the best wildlife lens of all time unless you only shoot elephants and hippos.
Having said that 300/2.8 is certainly light and very high performance.

Could Nikon make 400/4.5 sharper and higher quality, I would think they could. It is not always technology that limits what Nikon can do but also marketing, price point and position in the market. Nikon has so many options for 400mm, from 400/2.8s TC down to 28-400. When they think of light weight 400 prime, I don't think the best lens is the only criteria but the best lens they can make at a certain price point that would fit in with their lineup.
If given unlimited budget and no marketing consideration, would they be able to make a higher quailty 400/4.5 lens, I would think that they could. If they think the market would support 400/4.5 at the same price point as 300/2.8 and it won't eat up their 400/2.8s TC sale, they probably would have make one.

I think when discussing a 300/2.8 for wildlife, people often expect to use it with TCs, and in this particular lens's case many users seem to be happy with the performance. The light weight and compact size makes it easier to use it more varied conditions, for example, walking about in the forest or on hills, either the Sony 300/2.8 or the Nikon 400/4.5 are easy to work with. The 400/4.5 Nikkor is considerably lighter than the Sony 300/2.8 with 1.4 X TC on, though, but one could then argue that some of Sony's camera bodies are lighter and that would compensate for the difference to some extent. However, the position of the weight along the optical axis is also important and for me at least having as much of the weight close to my body as possible makes hand-held use easier. The 300/2.8 Nikkor is quite a challenge to hand-hold though I do do that when e.g. photographing figure skating, but walking inside a forest with hills, snow, and/or bushes I would not consider comfortable with that lens or any 400/2.8. The 400/4.5, 300/4 PF by contrast are very nice to use in such an environment. Are they too short? No, for large mammals they're not since the trees limit visibility over long distances anyway. Also, if you're in a hide, a wide variety of focal lengths can be used successfully.

Here there has been a shift from photographs showing the animals in their environment and some activity to showing a close-up of a single animal due to instagram and similar presentation platforms where it's not possible to really show landscapes in good detail, with animals. Instant attention and impact is there the game, I suppose. However, if you shoot for gallery or wall display then showing landscapes with animals or animals in their environment, then shorter focal lengths are suitable for that. Ultimately how an animal looks is not very interesting as we've seen so many examples of that. But if you can show some activity or animals in the grander scene of nature, that's much more interesting IMO. If you look at the statistics of the 100 best (selected by judges) images of the Wildlife Photographer of the Year competition, it is typical that the average focal length is not that long (less than 300 mm).

I agree that there is the pricing and position in the lineup to consider; at this price it's better (sharper and has arguably nicer bokeh) than the 100-400 mm at 400 mm, focuses faster, has a larger maximum aperture, and is lighter as well, but the difference is not that big. The 400/2.8 TC of course is a completely different class of a lens with extremely high price but such lenses are not that comfortable to walk around in a position ready to shoot, which in practice limit the buyer base and use cases. Of course, the f/4.5 aperture of the 400/4.5 also limits the uses of that lens. There is something for everyone in the Z telephoto lineup, at least for wildlife and birds. For indoor sports, concerts etc. 200/2 and 300/2.8 would be useful and are still missing. I would expect a 300/2.8 or 120-300/2.8 within a few years, personally I would hope it is a prime priced similarly to other 300/2.8 lenses as I really don't need yet another telezoom, least of all a 10k€+ lens. People who are like US secretary Bessent recently suggested, owning 5-12 houses, might not care about the price, but there are not that many of those people around. And in the future the excess concentration of wealth in the hands of a few might lead to another world war as it has in the past, after which there are no guarantees that anyone can afford anything. IMO lenses like the 400/4.5 are very important because of the wide range of uses and relatively affordable price, and it's really great that Nikon covers this upper intermediate-level market.

I wrote 200mm f2.8 not 200mm f2.0. And there you have the answer why we still have 135mm f1.8 lenses, they are 1 stop+ brighter.

Besides, if you are right that 200mm isn't a very useful focal length, why are 70-200mm f2.8 way more popular than cheaper and lighter 70-180mm f2.8 lenses? Part of it may be that they are higher end, but the truth is that many photographers use their 70-200mm f2.8 at 200mm very often.

It doesn’t seem that the 300 GM uses any XA elements, so there goes that theory.

With all due respect to him, I am not impressed by the quality of those images. I suspect the reason it's going to win Featured Thread is more due to the subject (male northern harriers) being very elusive and difficult to capture. Maybe it's how he processed the images, but they have a lot of artifacts from excessive sharpening. I'm not super familiar with how the 300GM performs with TCs, but I suspect that thread isn't a great demonstration.

EDIT: Here's a thread of his that I think better demonstrates what the 300GM + 2X TC can do: https://www.fredmiranda.com/forum/topic/1926287/

If you can't make a sharp, printable, sellable, or publishable image with the Nikon 400mm f4.5 w/ or without a 1.4x at maximum aperture, then you best work on... 1. Your technique 2. Your composition 3. Your angle of light 4. Your post-processing.

All of this talk about good - better - best lenses is mostly overblown in our current era. Even average lenses can produce amazing images... there is way more to compelling photography than the so-called best in optics can compensate for. Theres nothing wrong with having the "best" lens... but in the right situation and the right mindset, my soft and overweight 180-600 Zoom can produce better images than my near perfect 400mm f2.8TC.

bruce
