According to this MF photographer, there are limitations…

After receiving a newsletter from DP Review about the Phase One Mamiya – Leaf tie-up , one commentator, kb2zuz; (Kurt Heumiller)-USA, who shoots for the Yale Center for British Art, with a Hasselblad H3D-II 39 MS and H4D 50 MS, had this to say about the Medium Format  debate (added below for those without restricted internet access):

What are the mythical advantages of sensor size (or the often related larger pixels)? Less noise, better dynamic range, shallower depth of field. I work with an H4D every day, … I can tell you this, at anything over 50 ISO it has worse noise than any 35mm “full-frame” digital I’ve seen. It has only slightly better dynamic range (and again, that’s only at 50 ISO). Yes with the 120mm f/4 lens it will have a shallower depth of field than an 85mm lens on a full-frame at f/4, but you can get f/1.2 lenses for full-frame. Most MF lenses are f/2.8 or slower, there’s a couple f/2.2 lenses… so there goes the DOF advantage. I use medium format every day and there are reasons for it: multi-shot uninterpolated images, no AA filter, and high megapixels. That’s about it.

I’m no expert on MF, but I’ve long thought it would be better than FF or APS-C in all regards, at that sensor size, and I’ve seen jaw dropping images by MF photographers, but there are other factors I should have taken into consideration, (continue reading…)

Lunch Lizard © HarveyG Photography (seen 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. Distance to  subject about 180 cm / 70.9 in right at the cusp of closest focus. A small 70-300mm f/4.5-5.6 would also work as long as it’s the DG (full frame) and not the DC 18-250mm version. 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 1/800th or more preferably 1/1000th. 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 not so powerful a shot.

ETA 2012/01/19: ID just in! Thanks to to Trevor from Hardaker.co.za Common Flat Lizard (Platysaurus intermedius) Possibly male.

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

Well it’s back to the grindstone for most of us. Hope you all feel refreshed like these little guys and have a fabulous 2012!

and all those togs that can afford the new Nikon D4 should have a blast at the Olympics with it this year.

Thank you for reading this past year. Hope you have a safe peaceful holiday and a prosperous 2012. More regular updates in the new year and some exciting happenings and offers. Follow us on Twitter and Facebook too!

Discovered this today by accident. Super Video made by a DSLR! Love the 100-400mm pump action shottie. Looks like Forces of White vs the Dark Side…hehe. Enjoy!

Photographic Workshops:

Rietvlei is a hidden gem in close proximity to Pretoria (18km’s) and Johannesburg (38 km’s from OR Tambo Int. Airport). The reserve covers an area of almost 3800 hectares (38km²) and can support between 1500-2000 head of game. Currently some 1,600 head of game, including blesbuck, black wildebeest, red hartebeest, eland, Burchell’s zebra, waterbuck, reedbuck, springbuck, mountain reedbuck, steenbuck and grey duiker can be viewed here. There are other species but visit and find them for yourself From your own vehicle it is easy to spot these animals on the open endangered Bankenveld grassland plains. It is a relatively quiet unhurried reserve and well worth a full days visit. Rates are very reasonable.

The 60 km’s of tar and dirt roads in the reserve are fairly well maintained and serve for game viewing, park maintenance and for fire breaks in winter. Whilst a normal sedan can easily be driven around on the tar and most of the sand roads, there are some sections that require a vehicle with higher ground clearance. In the wet summer months I found that a double cab / bakkie with 4×4 or difflock capabilities allowed me to get into the odd area that I would not have gone with a family sedan due deep muddy ruts or washaways for fear of getting stuck. This is however the exception rather than the rule. Roads divide the reserve into 31 blocks and are well marked. A map, bird list and rules of the park are given to you when booking in. Rotation grazing is practised on the reserve by routinely burning blocks and using licks as supplementary feeding.

4 well located Bird-hides (2 on Rietvlei Dam and 1 on Marais Dam with the 4th one centrally located on marshland) and 2 main picnic areas with braai facilities are situated along these roads. There is also a very special river crossing called Otter Bridge with some wonderful wildlife (I won’t spoil it for you, go and check it out). (continue reading…)
