New Zoom Lenses!

1 September 2025 at 14:32

Just a short note this Monday morning as it's my pool day. I haven't spent a minute on the table since the news broke about TypePad going under, the longest stretch I've missed since the pool table was delivered, in an example of serendipitously great timing, right before COVID-19 hit. That was sweet. I spent many hours on the table during those 1–2 years of mostly quarantine.

As a result of the previous post, I am learning about some new zoom lenses that I hadn't heard about before. I'm going to go light on posting "Featured Comments" in the month of September, because the whole site will be coming down at the end of the month anyway (plus I hope I'm going to be busy this month, starting tomorrow—today is Labor Day in the US, a holiday), but I'll do Featured Comments on that post. Lots of interesting opinions and options.

One I hadn't heard of is the Tamron 35–150mm full-frame lens. That looks interesting. I've generally liked Tamron bokeh and from online samples it looks like I'd like it on that lens. Barely more than 4x at 4.2x, the range is unique and interesting. (A 4x zoom range is my longtime limit of what I'll consider for purchase—the more extreme the zoom range, the harder the lens is to correct without making it huge.) That would be a good candidate for pairing with a 21mm-e as a great two-lens kit. 

But the most interesting news (news to me, that would be): Sony now makes a lens with a unique zoom range, the 20–70mm ƒ/4. Only four inches long and a little over a pound in weight—nice. I wouldn't be bothered by the ƒ/4 speed—ISOs are so good so high now. The more extreme the speed with a zoom, the harder a lens is to correct without making it huge. And only 3.5x. It's meant to be a slower but wider full-frame alternative to the ubiquitous 24–70's that I was rather damning with faint praise yesterday (although, of course, we heard from several photographers for whom that range is perfect, and I've no argument with them—everyone's needs and prefs are different). Know how I'd use that one though? As a compact 30–105mm equivalent on the absolutely beautiful and wondrously solid APS-C Sonys that I liked so much, the current iteration being the A6700. I tried the A6300 and briefly owned an A6500, and loved them—such beautiful build quality and great hand-feel, with those big, beefy batteries that last and last. Round the zoom out with something like the Sony 11mm ƒ/1.8 for interiors and I'd be good to go with an efficient, portable, and nice-for-Mike two-lens kit. Yum.

The Mysterious Case of the Missing DN

24 July 2025 at 23:29

[UPDATE the following morning: That was interesting—the information in the post below, which I wrote yesterday using information from Sigma's and B&H's websites, is now obsolete and no longer correct. Literally overnight, not only have some of B&H Photo's listings for some of the I-Series Contemporary lenses changed, but Sigma's own web page for those lenses has changed as well. Sigma no longer includes the DG DN lenses on the Contemporary lenses page, but has added them to the "Discontinued" page. (It's also possible my search yesterday turned up an outdated page.) And several of the lenses I said were still available at the old prices at B&H Photo are no longer listed or are now listed as "Discontinued." It looks like the 65mm lens is the only one still available in L-mount at the old price. But I didn't check them all. Several of the older DG DN lenses look to still be available in Sony E mount at the old prices also. 

A couple of things I missed: the 45mm ƒ/2.8 DG (new style) (now $619, vs. the old price of $449) does feature a change: it now takes the magnetic lenscap used across the rest of the line, according to DPReview. And the obvious one: these lenses are now available in silver versions, to match the silver BF. —Mike]

 

I shoot Sigma L-mount now, and the other day I noticed something that outwardly looked weird. Some of the Contemporary series of lenses seemed to have a subtly new designation—the older lenses were "DG DN" and the newer lenses are just "DG." Not just on the sale pages; the change is also printed on the lenses themselves.

Dgdn-2

(Note: These illustrations show just the lower
part of the lens, not the whole lens)

This is the older and newer Contemporary 35mm ƒ/2. Note the printed lens designations.

Then I noticed something else weird. On the Sigma page for the lenses, both versions are listed and illustrated, but they don't seem to be right next to each other. For example, this 35mm ƒ/2 DG DN is in the middle of one row and plain DG is at the beginning of the next row down. The 24mm ƒ/3.5 has three lenses in between the DG DN and the DG. 

In Sigma-speak, DG is a lens for full-frame, and DN signifies (sigmafies?) a lens for mirrorless. So why did the "DN" disappear? 

I know, the suspense it killing you, so I'll cut to the chase. The old and new lenses are exactly the same. No changes. The new lenses are every bit as much for mirrorless as the original DN-marked lenses are.

Then...oh, duh. A number of the "new" DG-only lenses are more expensive. So do you suppose they put the lenses on the company web page farther away from each other to make it less likely that you'd compare the prices? Or does that sound like a TOP conspiracy theory? 

The ones that have gone up in price are the 17mm ƒ/4, 24mm ƒ/3.5, 24mm ƒ/2, 35mm ƒ/2, and 65mm ƒ/2. 

The ones that have stayed at the same price are the 20mm ƒ/2, 45mm ƒ/2.8, 50mm ƒ/2, and 90mm ƒ/2.8.

It appears that none of the Contemporary zoom lenses are yet available in a DG-only version. 

Should you be interested in snagging something at the old "DG DN" price, B&H Photo still has a couple of the DG DN marked lenses that look like they're based on the lower price: the 17mm ƒ/4 DG DN, L-mount, $599 (same as Sigma list price) and the 65mm ƒ/2 DG DN, L-mount, $599 ($100 less than the Sigma list price for the old one; the new one is $769). The others are discontinued at the former prices. The 65mm has particularly nice bokeh if you're all right with the only mildly longer angle of view.

All those prices are for L-mount. Sony E-mount lenses might be different prices. Some look to be more, some less.

I really like this lens series. They have all-metal casings and very smooth operation, and metal lens hoods, even, and their performance is beyond reproach, at least the two I've tried. I've been meaning to buy a 90mm. Now is probably the time. [UPDATE: too late.]

Jim Kofron (partial comment): "Sigma did announce a price increase due to the tariffs. I have a 90mm on backorder from B&H; I think it's supposed to come in September. I doubt that they will 'give it' to me for the original backorder price. The new I-series lenses were all getting the makeover (with magnetic caps, etc). I have a new 45mm and an older 17mm (both for my black Sigma BF). As for the Sigma BF, I'm really enjoying that camera. I've never had a Sigma that was so fast and rock-solid on autofocus—it's quite a treat!"

SongRaw Moonlit: BHNs Are a Bonafide Fad, Folks

20 July 2025 at 18:24

Pentax70 copy

The fad from my time, in a current lens

It's official: this is an era. The era of what I've snarkily dubbed the great big honkin' normal (BHN) lens. It's a distinct fad or craze that will probably be dated one day. 

Here's DPReview's article about the forthcoming SongRaw Moonlit (15 elements in 10 groups, four ED [extra-low dispersion] elements, seven HR [high refractive index] elements, two aspherical elements). It's alleged to be the first full-frame ƒ/1.2 autofocus lens from a Chinese maker. No specs, prices, or availability in my country yet, that I know of. It appears to be Shenzhen SongRaw's only product so far.

These things don't appeal to me, but there might be a reason for that. In the early 1970s (I was 14 in 1971), Olympus made the first of its popular miniaturized 35mm bodies. Then-mighty Pentax followed suit—ever held an ME Super? Even Nikon, king of pro cameras back then, responded with a few small and svelte models: not just the FM and its similar-bodied stablemates; a few diehard iconoclasts will remember the EM and the Series-E lenses. The Contax 139Q that I went through photography school with was reasonably within the boundaries of the small and light body styles of the day. (I later got the larger, heavier Contax RTS II, and, to my surprise, didn't like it as well. It was promptly stolen from me, which I accepted as a sign from the Universe.) Leica rangefinders had always been small, at least as defined at the time—the Leica CL that my high school buddy Art Elkon had was even smaller. The Leica M lenses and the wonderful OM Zuiko line were mostly very light, small, and compact. The Leica C (for "compact") lenses for the CL even more so. That was the fashion at that time. It would be interesting to put the Olympus OM-Zuiko 50mm ƒ/1.2 next to the Songraw Moonlit. It might look like an original Austin Mini next to a Hummer*. 

Small and light was the fad that I grew up with, is all. It was what was cool at the time. That's probably mostly why I like it. I got a little endorphin charge when I saw the Pentax 70mm ƒ/2.4 again, that I will be sending out with the Pentax Monochrome body—130g (4.6 oz.) with its built-in hood. That's it in the top illustration—and it's bigger than the 21mm that will also be in the box.

I suspect that today's younger photography and camera enthusiasts are growing up with a different fashion holding sway—and that when they're my age now, they'll be looking back with rosy nostalgia on the great big lenses of now as "the way things are supposed to be." They'll get that little charge when they see a great big oversized lens...like an old SongRaw Moonlit.

Nothing new under the sun.... 

Here's the manufacturer page for the SongRaw Moonlit. Pretty images. And a slick and well-made page, complete with MTF curves for ƒ/1.2 and ƒ/1.4.

Mike

CORRECTION: The first version of this article said the Moonlit is the first ƒ/1.2 lens from a Chinese lensmaker. It is the first full-frame autofocus lens of that speed. Management regrets the error, and will fire the writer as soon as a replacement is found.

*Actually the smallest car I ever saw (and sat in!) was the original Honda Civic. A dealer had one on display. It was a little larger than, say, a suit of armor.

That's an early Doug video, by the way. He's now a YouTube multimillionaire.

Featured Comments from:

Sroyon: "I was born after the Olympus OM/Pentax ME era, but like you I'm a fan of small lenses. Nevertheless I was thinking perhaps we should differentiate between fast BHN (with a max aperture of ƒ/1.2 or wider) like the SongRaw, versus not-so-fast BHN (ƒ/1.4 and smaller). The way I see it, a full-frame autofocus ƒ/1.2 lens is bound to be big, unless they make dramatic compromises in optical quality. Whereas the not-so-fast BHN are generally big because the manufacturers wanted to make a lens which is extraordinarily well-corrected, at the expense of compactness and weight. Thus the motivations of people who buy fast versus not-so-fast BHN are probably somewhat different. Also I feel there are lots of new lenses being produced in general, especially with all the Chinese manufacturers joining the party. Including some very small lenses like the new Fuji 23mm ƒ/2.8, and 7Artisans' new 10mm ƒ/3.5. So there's a market for that too!"

Tom Burke: "Partaking as I do in a (different) forum dedicated for users of the Canon mirrorless camera that I use, I can report that a number of people buy a BHN (or the APS-C equivalent) because they’ve been told that the wider the maximum aperture, the greater the lens is. Having bought the lens, they then use it at that maximum aperture for most of their shots. Until they appeal for advice to the forum, at which point someone advises them to use a smaller aperture. But there’s a definite belief out there that an ƒ/1.4 or wider lens must be better than an ƒ/2 or even ƒ/2.8 lens, at all apertures."

BG: "Big honkin' cameras and big honkin' lenses were popular back in the SLR era, too. It's the macho I'm-a-serious he-man photographer thing. Look at the size of my cameras; it proves I am serious. Nothing changes over time...."

Maggie Osterberg: "When I was a teenager, I wanted everyone to know that I was a PROFESSIONAL PHOTOGRAPHER dammit! So, I had a big Nikon SLR, with a big potato-masher flash, and a big lens. Which looked pretty ridiculous on my then 5'2" frame! But by golly, folks knew I was serious. By the time I got to my forties, I figured out that unless you're shooting sports, big ≠ good. Best thing I ever did was to get a Leica, with nice small lenses, and then an X100. As E.F. Schumacher wrote, 'Small Is Beautiful.'"

James: "You could, instead of complaining, herald the Sigma Contemporary DG DN series. The 45mm is, in particular, a standout."

Mike replies: James, that's my lens.
