Review: A New Lens for Harold (the Irix 150mm “Dragonfly” macro)

Piercing the Iris Veil © Harold Davis

I photographed these close-ups of flower petals (image above: an Iris; image below: the petals of a Gerbera from behind) with a new lens, the Irix 150mm f/2.8 “Dragonfly” telephoto 1:1 macro. For a telephoto macro, this is a relatively inexpensive lens (about $600 recently at B&H). Apparently, the Irix lenses are designed in Switzerland, and manufactured in Korea.

The lens comes in a nice box, with a useful hard pouch for storage, amenities such as two rear lens caps and a nice lens hood, has a functional tripod collar with an Arca-mount foot that lets you switch from horizontal to vertical and back again, and is handsomely finished. It appears solidly made, with good materials in the right places.

That said, I did have a build quality issue with the first one I ordered from B&H, so I had to send it back for an exchange. I won’t go into details about what the problem was, except to note that it was a show-stopper (if you need to know, drop me an email). The build-quality issue suggests that if you buy one, make sure you buy from a reputable source, test it thoroughly during the return period, and send it back if necessary.

A complaint about the lens design is that it lacks a manual aperture ring, at least in the Nikon F mount (I haven’t tried the Canon or Sony E mount versions, so I can’t verify that this holds cross-platform, but it probably does). The expectation is that you are going to set the aperture using the camera.

This is a serious drawback in a lens that is likely to be used in technical circumstances, as is the case with a telephoto macro. In particular, if you use the lens with a bellows or an extension tube that has a manual diaphragm coupling (not an uncommon scenario with a lens of this sort), the only way to change the aperture that I could figure out is to dismount the whole lens-and-bellows, put the lens (or another lens) on, then reset the aperture, which will stick even after the lens is remounted on the bellows.

Somewhat counteracting this complaint, a nice bonus feature is a solid focus lock. This is useful when the lens is on a tripod and pointed downward, and you want to make a long exposure without having the focus slip.

This is a sophisticated, solidly built lens. According to the manufacturer, the aperture mechanism includes 11 rounded blades, designed to create pleasing bokeh (background blurring). The manual focus mechanism is solid and lends itself to precision. The lens has been weather sealed at key points.  

Again according to the manufacturer, “The optical design consists of twelve elements – three of which are made of super-low dispersion glass (ED), another four of glass with a higher refractive index (HR), and the whole arranged into nine optical groups. Thanks to this construction, we obtain an close to zero distortion (at a level of 0.1%).”

Folks who know me well know that I collect macro lenses; in fact, I have been called “the Imelda Marcos” of macro lenses. I think I’ve lost track of how many I own, and I’m pleased to add this Dragonfly to my collection. It fills a gap between my Nikkor 200mm f/4 macro and the Nikkor 105mm and Zeiss 100mm macros. Subjectively, I think it beats the Nikkor 200mm (which only focuses to 1:2 rather than the 1:1 of the Dragonfly) in terms of sharpness, although it may not be quite up to the Nikkor 105mm or Zeiss 100mm. Even here, the modern design and coatings help with the comparison, and I like the extra reach of the 150mm focal length.

Probably the closest comparable lenses are the Canon 180mm macro (which won’t help Nikon users), and the Sigma 180mm telephoto macro, which by reputation is a great lens (I don’t own one), but considerably more expensive than the Irix.

So enough technical talk and comparison of other macro lenses. What I really think is below the image.

What Harold really thinks: First, both the images that accompany this story were made with the Irix 150mm f/2.8 “Dragonfly” stopped down to f/32. Obviously, these results are pleasing, with limited diffraction considering the small aperture, and I am happy to own this lens. I expect this to be a go-to telephoto macro lens in situations in which this specialized optic is called for.

Disclosures: None. I have no relationship whatsoever with Irix, and bought the lens with my own hard-earned cash money.

Old and New: A Tale of Two Kirk BH-3 Ball Heads

My Kirk BH-3 tripod ball head has served me well on four continents on the trail, in the studio, in mountains, deserts, and along the rugged Pacific host, from the barrios of Havana to the souks of Morocco and the Boulevards of Paris. So one day recently, when my BH-3 reported to duty with a definite kink in the retaining plate bracket and knob, it was with sadness that I replaced him in favor of a brand spanking new model. Time goes by, and since change is incremental one doesn’t see the markings until there is a new one for comparison.

As I’ve noted, technique is not at the apex of the Maslowvian triangle of photographic needs (vision is), but technique is still my craft, and I am very fond of the tools that help me practice my craft, and want to give my old BH-3 ball head the most honorable send off possible, as it retires and becomes a paper weight and conversation piece rather than an ongoing part of my day-to-day photographic life.

Review: Domke Next Generation Chronicle Camera Bag

If you are like me—and most other professional photographers that I know—you will have acquired over time an extensive collection of camera bags. Some bags fit some gear, but not other gear. Some are backpacks—which means better ergonomics for trekking, but less access to gear on the fly—and others are shoulder bags. Still others are hybrids, or designed particularly with transiting through airports, or being able to submerge in water, in mind.

I am always looking for the perfect camera bag, and with my Domke Next Generation Chronicle I may have finally hit the jackpot.

The Domke bags were originally created by photojournalist Jim Domke, whose hobby was collecting camera bags. Started in 1976, the Domke company was acquired by Tiffen, a leading manufacturer of photo accessories, in 1999. You can visit the Domke page on the Tiffen website by clicking here (opens in a new window).

Over the years, many professional photographers have provided input into the design of the Domke camera bags, and they have received numerous professional accolades, such as being named the official bag of the White House News Photographer Association.

It’s clear that no one bag will ever fulfill all of my photographic needs, or hold all my camera gear—and, as Jim Domke would be the first to admit, it is highly unreasonable to have this as an expectation. Within the constraints of a soft-sided journalist-style shoulder bag, my Domke Chronicle Camera Bag is truly wonderful. This is not an inexpensive camera bag (the discounted retail price is probably about $300), but the old saw about getting what you pay for applies, and the materials, finish, and detailing are top-of-the-line throughout.

J-CHRON-RM_300-8wThe outer material is a durable, water repellent form of thick coated cotton duck, manufactured to military standards. Hardware, such as zippers and clips, are very high quality. One thing I like best is that the exterior, while attractive, is non-descript. If you remove the external Domke badge, which is easy to do, no one would ever know this was a camera bag. I carry thousands, or tens of thousands, of dollars of camera gear through all kinds of environments, and an extremely important component of personal security is not giving away what I have with me unnecessarily (partly for this reason, I also replace the branded straps on my camera bodies with plain straps).

Inside, the bag is flexible and expandable, and also protects my gear. Did I mention that this is a softside bag that is lightweight? I’ve carried it happily with one camera body and two lenses, and I’ve also used it fully loaded with several bodies and five or six heavy lenses. The customizable divisors allow a great deal of flexibility about how much gear I carry, and how it is laid out.

Chronicle-OpenThe layout of pockets for things like filters, memory cards, extra batteries, iPad and iPhone, and so on is very well thought out. Two features I particularly like are the excellent and secure strap for placing the bag on a wheeled suitcase extension handle, and the closure of the main compartment. The main compartment is secured with heavy-duty steel clips, but if you forget to clip it and just throw the top over, velcro takes over, and your gear will still be safe.

My one complaint about the bag, and I have only one, has to do with waterproofing. The material the bag is made of is inherently highly water resistant, and the main compartment is designed with flaps that can be arranged so that water does not leak into the bag. This arrangement is probably more than sufficient for the intended primary users of the bag, who are photojournalists. If it starts to rain hard, the photojournalist probably stops into a handy cafe and interviews sources while sipping a Pernod or Ouzo, and maybe puffing on a cheroot.

In contrast, my way of working sometimes requires me to be out with my gear in extremely foul weather. My requirements for a bag include a completely waterproof (not water resistant) cover, either included as integral to the bag, or carried as an accessory in a pocket. Domke does not provide this, so Phyllis helped me sew a jury-rigged elasticized waterproof raincoat for the bag that I always carry in a pouch in one of the pockets.

Full disclosure: I was provided a Domke Next Generation Chronicle Camera Bag for the purposes of writing a review by the Tiffen Company, and tested it under many widely varying field conditions. While I didn’t pay for my Chronicle Bag, I never would have trusted my gear to it on several continents if I didn’t think it was a great, convenient, and well-made camera bag, and my opinions are always honest and outspoken.

As a matter of principle, and so I can stay objective, I do not carry advertising or affiliate marketing links on my blog. Domke Camera Bags can be purchased from most quality professional photo suppliers.
