Levaillant’s cuckoo. Lifer. Photographed on a getaway, workshop near the town of Hoedspruit, Limpopo, South Africa. Amazing what one can see when making the effort, taking the time and being persistent. A bit skittish it seldom allowed me to get close than about 3 or 4 car lengths and it would fly off to another tree further on up the road.

The Levaillant’s cuckoo occurs in huge areas of sub-Saharan Africa, preferring Acacia, miombo and broad-leaved Burkea woodland. It is extremely secretive and hard to find, foraging in thick undergrowth. It almost exclusively parasitizes babblers, for reasons not understood. Egg-laying is an elaborate process, with the male distracting the host birds, while the female sneaks into the nest to lay its egg. Unlike many other cuckoos, the chick does not kill the host nestlings, in fact they often co-exist quite peacefully. The chick stays in the nest for about 9-10 days, becoming fully independent 3-5 weeks later. – http://www.biodiversityexplorer.org/

The workshop took us to Ekuthuleni Lodge overlooking the Oliphant’s River, some 23km from Hoedspruit in Limpopo Province, less than an hour’s drive from both the Phalaborwa and Orpen gates of the Kruger National Park. Offering thatched self-catering chalets and caravan sites, the resort provides great options for a true African bushed experience. Guests can enjoy game drives, self drives, excellent birding opportunities and the excitement of being positioned on the banks of the Oliphant’s River, with abundant wildlife to be viewed. The wonders of the Mpumalanga escarpment; the Blyde River Canyon, Bourke’s Luck potholes and God’s Window are also within easy driving distance. The sheer beauty of the area and it’s abundant wildlife is a photographers dream.

A self catering long weekend trip (Friday-Sunday) starting from R7,000-00 per person sharing suited for couples sharing. 3 couples per unit. Discounts for groups up to 12 can be arranged.

A full week long itinerary can be arranged with visits to a number of wildlife rehabilitation centres, Blyde River Canyon, Three Rondawels and many other photographic opportunities; landscape, wildlife and people. Pricing from R10,000-00 per person sharing.

Sigmalogo-tudor

Tudortech (South Africa) the official Sigma distributors throughout the African continent, last week kindly dropped off two brand new professional lenses for me to review. The 85mm f/1.4 EX DG HSM as well as the new 70-200mm f/2.8 EX DG HSM OS. Thank you Michael from Sigma/Tudortech and Colleen from CMN Marketing.

Sigma call this “The Ultimate Wedding & Portrait Lens” and with it’s large aperture and medium telephoto lens focal length plus the pro rounded 9 blade diaphragm it is going to give hand held low-light shooting with a smooth, dreamy bokeh. It will become your “make money” lens. (See next blog entry (Sigma 85mm EX DG HSM f/1.4 (Part 2) Review) for technical report and some wow images.)

Beautifully boxed and with their 3 year local warranty sticker proudly visible; a huge stamp of product confidence and should allay any fears of the backing and commitment of the brand. Not that I’ve had any major mishaps after using several Sigma’s dating from ’91, all of which are still functioning perfectly today even after migrating from film to digital bodies and despite being subjected to years of use in dusty and hot game reserves, outdoor (sometimes wet – skidpan) event photography, commercial work, freezing night shoots and in a tame studio.

I unwrapped the sealed plastic, opened the box and packaging, removed the decent carry bag and extracted the lens. It felt solid as I lifted it out the box. With it’s distinct metallic gold ring that denotes their Professional EX Range of lenses, the 85er beckoned for a product shoot before it ended up with dust and finger prints.

A full frame lens for FX / APS-H DSLR’s but it can naturally be used on DX / APS-C sensors at 1.5x (Sigma, Nikon, Pentax, Sony) or 1.6x (Canon) crop factor, it oozes build quality. At a massive 130mm on DX at f/1.4 you have to use your feet to get your composition and you will need a deep studio in order to back pedal if shooting models full length. No “lazy user” zoom rings here. On a plus you no longer have to shove your lens into your models face to get that eye or lash close up :)

From it’s large focus ring grip, a well positioned big positive action AF/M thumb switch to the metal bayonet mount this lens is not your standard plastic fantastic. I popped on the lens hood (The hood extension is not shown but is included, provides better protection from flare when used on APS-C DSLR’s, this is unique from a lens maker) and then with a solid tight bayonet click onto the DSLR I felt no slap or play at all. Fairly well balanced weight with the DSLR+GRIP, perhaps a tad nose heavy in comparison to my studio 28-80mm f/2.8 zoom. Raised it to my eye and looked through the viewfinder…whoa! Bright! I thought my Sigma 28-70mm f/2.8 was bright…it’s amazing what two full stops of light makes. I snapped off a few images indoors in ambient but subdued light and the bright crisp results and fast shutter speeds were just amazing. The last time I held such a fast lens in my hands was in the 80′s with my Rokkor-X MD 50mm f/1.2 but that was a feather weight in comparison. I still have that lens and am tempted to do a side by side photo shoot. Not that I found the 85er in the Gerrie Coetzee class, but it is physically more rotund than a 35mm MF 50mm and looks like it means business.

So into the studio with one 300w strobe, diffusers, a Gossen DigiPro F Light Meter, my trusty D90 and the tripod. An hour later I had a few quality (sexy) original images of the 85er attached to a D7000. The least I could do for the kind folks at Tudortech.

All the product images above were shot with my own workhorse; a 2009 Sigma 28-70mm EX DG f/2.8  :)
If you are looking to purchase one please drop me an email.
RRP is surprisingly good value at +/- ZAR R9000-00 inc VAT ($970-00) excluding delivery or professional tuition for a lens that will last you well throughout your career.

Needless to say I took a number of snaps with it around the studio. I also took it to Zwartkops Raceway on Saturday and coupled it to a D300s and D7000…images and technical write-up to follow shortly but here’s some teaser images. Both are SOOC (Straight Out Of Camera, untouched, uncropped, resized).

During April I will have a chance to do a boudoir shoot and hope by then to have the 85er down pat to capture some sensual and dreamy images.

Nikon have just announced an updated version of their 80-400mm 5x telephoto zoom lens with Super ED glass and Nano Crystal Coat. It also has a revision of their VR (II, not the latest III) technology and a different lens design from its predecessor in further reducing CA. Whilst I can’t confirm this on Nikon’s website, others have reported the new lens to have weather sealing…?

Lens construction:
20 elements in 12 groups (including 4 ED glass and 1 Super ED glass elements, and Nano Crystal Coat)
17 elements in 11 groups (3 ED glass elements)
Due it’s IF motor it will now AF on all the consumer Nikon DSLR’s as well as the Pro-Sumer and Pro FX models.
DX D40, D60, D70, D80, D90, D2x, D2xx, D3xxx, D5xxx, D7xxx, D300, D300s
The reach on DX is an effective 120-600mm from f/4.5 to f/5.6 on DX. An ideal reach with an additional stated 4 stops of VR effectiveness.
FX D700, D3, D3s, D3x, D600, D700, D800, D4.
On today’s High ISO Low Noise sensors and the stated improvements of Super ED coated lens I’m keen to see the results. Even on FX it should be a useful all round lens for those who do not have the $5000+ for a prime.

03/2013: AF-S 80-400mm f/4.5-5.6G ED VR2

06/2001: AF 80-400mm f/4.5-5.6D ED VR1

 

 

 

 

 

 

To quote Nikon:

The Nikon AF-S NIKKOR 80-400mm f/4.5-5.6G ED VR Lens is a telephoto zoom lens that is compatible with both FX and DX-sized image sensors. This lens features an extensive zoom range that encompasses both portrait lengths and long-reaching telephoto lengths to suit working with a variety of subjects.

The lens construction integrates one super ED (extra-low dispersion) and four ED glass elements to help minimize chromatic aberrations throughout the zoom range and also contribute to higher image sharpness, clarity, and color fidelity. A Nano Crystal Coat is also applied to individual lens elements to help reduce surface reflections and prevent lens flare and ghosting for greater overall contrast and light transmission. Built-in Vibration Reduction image stabilization also lends itself to producing sharper imagery by compensating for the effects of camera shake up to the equivalent of four shutter speed steps. Additionally, a dedicated VR setting for tripods is available for producing the sharpest imagery possible without countering the effects of the image stabilization system.

The MTF graphs look very promising & I trust real world use on today’s 16, 24 and 36MP DSLR’s provide exceptional results.
