Lunch Lizard © HarveyG Photography (published on SigmaPhoto.com)

I lay flat on my stomach for an hour watching this guy catch his lunch during a workshop/getaway in and around Hoedspruit, Limpopo, South Africa. Used a Sigma 100-300mm f/4 APO EX DG APO HSM full-frame non-stabilised lens on the D90 (Sadly it is discontinued by Sigma as they have replaced it with a 120-300mm f/2.8 and I’m counting pennies ;p ) This gives me the effective range of 150-450mm on the DX small-frame sensor of the D90 (remember the D90 has exactly the same sensor as the D300s). Distance to subject about 180 cm / 70.9″ right at the cusp of closest focus. A “kit” 70-300mm f/4.5-5.6 would also work as long as it’s the DG (full frame) that has that extra reach, and not the DC 18-250mm version. I shot a lot of my early work with 70-300mm f/slows and they are very versatile. A 55-200mm VR or any equivalent new 70-300mm VR DX/OS DC lens will work, but you have to get closer and often these subjects have a personal space of a few meters.

Note the low POV. Critical in getting more powerful images. I wished more people would do that with their pet images on Facebook!

The lizard polished off at least half a dozen insects and larvae in one hour. They are so fast that by the time he’s scampered to catch the fallen insect he’s half swallowed it already before you get a shot. You have to be spot on with focus and constantly alert. Shutter priority is the way to go and once you have mastered that go aperture priority but keep an eye on the shutter speed. At least double the speed of the maximum focal length of your lens to get a sharp unblurred image. In my case that would be 1/1000th (300mm full frame lens x 1.5x crop factor = 450mm x 2 = 900). A bean bag is handy as this big lens weighs 1480 g / 52.2 oz, and gets harder to hold as time goes by, however the POV is then slightly higher and perhaps not as powerful a shot.

Watching him snack bugs reminded me of The Crunchy Frog sketch by Monty Python:

To watch the mothers and children initially playing in the mud was so much fun. Then the old bull emerged from the bush, where he was hidden from our view feeding. With a flick of his trunk and a subtle move of his body the entire herd stopped playing, as if chided by him, and then proceeded to regroup and leave the water sports in the dam to go dry off. It was inspiring to witness the interaction and intelligence of these massive creatures, and yet not a sound was made by any one of them. Read on to see an edited image and decide what impact that has overall.

I’ve been asked that dreaded question again:
Q: More Mega-pixels is better, right?
A: Sure, if you can afford an H4d-200MS or 645DF & IQ180 Medium Format…with a lens or two.
Q: What’s Medium Format?
A: * Sigh *

Nikon Canon Nikon Canon ...

Has aggressive marketing and consumerism made potential DSLR buyers really believe that N is better than C or C better than N thanks to the Mega-pixel count of the latest release? Are Mega-pixels the be all and end all buying factor of the perceived quality of a digital camera and thus the only basis for a purchasing decision? It’s as bad a question as the “What camera is better? Nikon or Canon?” Define “better”?

What about Sony, Sigma, Pentax, Kodak, Olympus, Fuji, Samsung, Panasonic, Leica, Hasselblad, Phase One, Mamiya, Zeiss etc. Are they no good? Never heard of them? Won’t consider them?

Sensor Sizes (Not to scale) Image courtesy Wikipedia. Click on the image to go their comprehensive sensor article.

What about the actual sensor dimensions used in various iterations of all these brands and cameras?
What about the TYPE of sensor, the design and the technology of the actual sensors that record the image? There are many different types of sensors each with their own unique design and improvements over the years. How does the manufacturers in-camera image processing software algorithms shape up? Do you need to shoot low light without flash? Are you only shooting in natural light. Wildlife, events, PJ? How about studio work?
Are lenses/glass quality also not part of this equation? Do you want one lens that goes from wide angle for landscapes to 600x zoom for spotting the tick on a Warthog’s butt at 200 meters? It’s ok, it’s got anti-shake! Will it still be as sharp on a P&S 600mm 12Mp with 1/1.8″ sensor (24.7mm²) as on a full frame 24Mp with 600mm f/4? with a 35mm (370 mm²) sensor? What about the signal-noise ratio? The larger sensor also has less clipping.

Based on ones need, I can make a purchasing suggestion wrt body, make, model, lens and sensor type/mega-pixel choice. It’s about the intended use, not only the Mp. Get a FF DSLR and the 4 or 5 lenses you will need to go from Ultra Wide Angle to Super Zoom at 800mm. Now try sneak it on as hand luggage on your way to the Serengeti.

There is not one definitive answer unless money is no object. Note that these two cameras are used in mostly studio and product photography and may not be ideal or practical for wildlife, astronomy, your next fishing trip (or event work?) due lens selection and body size, practicality and even weather resistance:

Who here has seen (drooled over) the Hasselblad H4D-200MS yet?

Hasselblad H4D-200MS - CCD based back.

Or the Phase One 645DF with IQ180 Digital Back?

Phase One 645DF - CCD based back.

In order to answer the More Mp is better question:

What is your intended use of the camera? (Holiday snaps to billboard advertisements of supercars/models).
What print size do you want? (Postcard or a wall mounted A1 Canvas?)
What is your budget!? (How deep are your pockets?)
Have you got old AF or MF lenses from the film days and what brand? (Saving money on glass allows you to spend more on new body technology)
How big are your hands and how strong is your back? (Good glass weighs a tonne)

You can see where I am going with this… (continue reading…)

Despite 4 hours of standing outdoors in the freezing Highveld winter near Jo’burg, it was fun! What photography isn’t? Thanks to my friend Wayne for letting me shoot on his plot and keeping the coffee, red wine and conversation flowing! I eventually lost the feeling in my feet, it was so cold. The joys of outdoor photography

I’ve only just started posting to DP Review and am quite excited to have one of my images achieve a top 10 (9th out of 200 entries) in a very short space of time. Candid portraiture is a speciality and favourite photographic subject of mine, especially at events I shoot.

The winner of the competition was another South African, Joggie Van Staden with “Joyfull”. Well done Joggie! Classic portrait and wonderful emotion.
