Sigma 18-300mm C

• Sigma has confirmed the upcoming release of the 18-300 f/3.5-6.3 DC OS HSM Contemporary for Canon, Nikon and Sigma cameras (read the statement). Unlike the 150-600mm Sports, this lens should not suffer from any shortage…

• The AML 72-01 close-up lens, that enables to reach 1:2 magnification ratio with the above lens, can be pre-ordered at B&H Photo.

This lens features an apochromatic design and maintains the original lens’ quality throughout the zoom range from 80mm to 300mm focal length positions. When in use, the minimum focusing distance of 15.4″, and 5.5″ working distance, is retained.

Judging by the expected magnification ratio of 1:2 magnification in combination with the 18-300mm C, this magnifying glass seems to be relatively weak (1 diopter?), which also means that it should affect image quality only very mildly.

Of course, it can be used with any lens that sports a 72mm filter thread, but as any close-up filter, it is better matched to telephoto lenses. For instance, a maximum reproduction ratio of around 1.3:1 can be obtained by pairing it to the Sigma 150mm f/2.8 DG (OS) HSM Macro (1:1 natively).

Delivery delays expected for the Sigma 150-600mm telephoto zoom lens

Pre-order the Sigma 150-600mm f/5-6.3 DG OS HSM Sports: Adorama | B&H Photo | Amazon US | More options

Sigma has posted a notice (English translation) regarding the availability of the Sigma 150-600mm f/5-6.3 Sports.

While the lens will start shipping on October 24th, initial supply will be too low to satisfy the higher-than-expected demand. The first batches will serve to fulfill pre-orders until production catches up, so we may not see it in stock for a while.

Interest in the Sigma 150-600mm f/5-6.3 DG OS HSM Sports is significant enough to open a dedicated post.

If you’re on the fence about buying the lens, I advise you to bookmark this page, as it will be updated regularly!

Sigma has been rumored to have a 24-70mm f/2 DG design in the works since the early days of the Global Vision line.

Here are a few words about the ins and outs of such a lens.

Design constraints

Naturally the goal is to have a reasonably sharp lens wide open at all focal lengths and throughout the frame, which for a full-frame 24-70mm f/2 requires huge design efforts. Issues like field curvature would be very hard to keep at low levels. If high wide-open performance can only be achieved with 2 kg of glass, the lens is unlikely to see the light of day.

The pair of 150-600mm f/5-6.3 lenses offers a good example of size increase (and price increase, subsequently) due to a higher-performing design… while the aperture is the same for both lenses!

Reducing the range would put much less stress on the optics − and on the engineers. Thing is, a shorter range would be less appealing, especially compared to f/1.4 primes.

Eat the sales of the primes?

The main point for a 24-70mm f/2 lens is the versatility. One stop of extra light versus the primes (35mm f/1.4, 50mm f/1.4, and the future 24mm f/1.4) won’t be enough for some users to keep considering them. Carrying a single lens instead of three is attractive.

Of course there are reasons to favor one or several f/1.4 prime lenses over a 24-70mm f/2, including the better optics (to some degree: less field curvature, less distortion, less CA, better bokeh…), the need/want for f/1.4, the need/habit to use a certain focal length… But I’m not sure this would be enough not to cannibalize sales of the fixed-focal-length lenses in this range, at least to some extent.

A regular 24-70mm f/2.8 design would keep the primes safe, and is the safest solution for Sigma. Actually, it is the most likely option.


A rumor has it that the lens could be priced below the Canon 24-70mm f/2.8L II USM. This sounds unrealistic, to say the least.

See the price gap between the two Canon 24-70mm lenses. The 24-70mm f/2.8L II USM (regular price $2,099) is more than twice as expensive as the one-stop-slower 24-70mm f/4L IS USM ($999.99), and the latter would cost less without image stabilization… So how much for a 24-70mm f/2? Even if we’re talking Sigma, I can’t imagine the lens to sell for less than $2k.

In the end, a good balance between all the aforementioned factors has to be found, to make sure the market does not reject the product. Tough task.

So could it be the very unique lens that was talked about recently? I doubt it, but there is room for speculation.

The new Sigma products will be released soon

The dp1 Quattro, 150-600mm f/5-6.3 Sports lens, new teleconverters and filters will be available starting October 24th in Japan, and “towards the end of this month” in the rest of the world, says Sigma Japan. No word on the 18-300mm f/3.5-6.3 Contemporary.

Some doubt remains about the worldwide release of the dp1 Quattro, since availability info is missing from the English page (see link below). Probably just an omission.

The release of Sigma Photo Pro 6.1 is also scheduled for October, so it should come with the camera.
