Feeding frenzy

What larks. Nikon announce two new 'flagship' cameras (FX and DX) and the fora are alive with the sound of photogeeks chewing over the specs. Oddly enough neither camera interests me beyond making one I own and want to part with likely to drop in price as the tech chasers offload their cameras (the model that replaced the one I have...). Better get it sold PDQ!

Coincidentally it's a camera I've been using recently and which still produces files I like the look of. The only things I hold against it are size and weight since getting used to my light camera. So what if it only has half the number of pixels. I've never needed all of them in any case.

Once more the internet experts have been driving me nuts. Photography is really simple these days. Cameras do so much of the heavy technical lifting for you it's easier to concentrate on making pictures. yet whenever a beginner asks a simple question that can be answered by 'put the camera in P mode to start with and learn the more technical aspects later' they get chapter and verse on the 'exposure triangle', or teh incverse square law, or hyperfocal distances or some other nonsense. All they want to know is the easiest way to get decent exposures and in focus subjects.

Then you get people offering advice on techniques they have never tried, but because they understand all the technical crap think they can help anyone. It was a query about how to improve fishing self portraits that has prompted this rant. When it comes to the technical stuff I stay away from offering advice on 'that photography forum' because I know my idiots guide approach to photography will just get shouted down. But I DO know how to take a decent trophy shot of myself holding a fish. So I posted my simple technique for success.

Even with examples of my own selfies the 'experts' continued to proffer their advice based on pure theory. In the end I couldn't take it any more and had to tell them to butt out... I should do more fishing or photography than forum watching but the weather's been off-putting. It brightened over the last couple of days but yet again a combination of work and waiting for parcels has kept me indoors. By the time I've been free it's gone dark! Still, I much prefer overcast days for vaguely landscapey subjects, but brighter ones than we've been getting of late.

The second day of the year saw me back at the reserve not photographing wildlife. The paradox of nature conservancy claiming to get people closer to nature while distancing them from it continues to intrigue me.


Look! An owl.

Somebody stop me!

I must stop putting the subject smack bang in the middle of the frame and taking symmetrical photos.


Anyway. I managed to get hold of another (used, naturally) copy of the lens I had to return last week. This one does as it should, and produces pics with then same visual qualities. Note; that's not the same as Image Quality, which is something gearheads take to mean 'sharpness'. Apart from it being small and light I really like the way the out of focus regions decay. Some cheapo lenses give harsh, almost jagged, out of focus areas. This one doesn't. It gives good bokeh.


Damn. That post's in the middle of the frame...

How out of focus areas appear is important. Not for the popular reason of using shallow depth of field for its own sake - which is a mannerism - but so that background detail can be 'read' even though it is out of focus. If it all goes to mush you lose context and are left with a subject floating around in space. Degraded detail maintains the context. Without knowing where something is, how it relates to its surroundings there's no 'story' to the picture.

While most camera nerds test lenses for sharpness with charts pinned to walls and their cameras set up precisely parallel to them on rock-solid tripods, I go out and take hand-held pictures of signs. Signs are good because the lettering and images have sharp edges, and they are sometimes printed on surfaces with fine textures. These two, when pixel-peeped, are as sharp as I need.



I quite like them as pictures too. Which is actually why I shot them. They just happened to provide a test of the lens's sharpness. Somehow I managed to make them unsymmetrical too.

Either I've been dead lucky, I'm not fussy, or a lot of internet-photographers are deluded, but I've yet to buy a Nikon lens which has needed to be adjusted to my camera bodies. I've fiddled with the fine tuning feature a couple of times and seen no difference. Maybe if my camera was always locked down on a tripod with the aperture wide open I'd see the need, but as I either shoot hand-held or with the lens stopped down when the camera is (rarely) on a tripod I either have enough depth of focus to hide imperfections, or they are likely to be messed up by my shaky hands anyway. In fact any focussing issues I have I always blame on poor technique rather than faulty or misaligned gear. More people ought to admit to their inadequacies in this department I reckon.

Looked at 100% on the computer this shot is sharp where it needs to be sharp - on the hook. No fine tuning, hand held, available light, and a lens which has a flake of crap inside it. It's the second frame. The first was well soft thanks to my dodgy technique. Nice bokeh, too...


Odd folk, carp anglers.

Shop talk

My local tackle shop would make a good place to base a project around. It's a family run business, father and son working  together, mother and daughter-in-law helping out plus two/three part time staff. A shop where the regulars (including myself!) pop in for a natter, hang around for far too long spending little most times might sound like a recipe for doom in the on-line age, but they have a web presence which is growing. So far the shop is demonstrating that the small independent tackle shop can survive in the face of megastores, discounters and web-only businesses.

From a photographic perspective there's a lot goes on during a day, then there's the customers - a  cast of characters straight out of the big book of northern clichés. It's a pity the boss keeps threatening me with violence every time I point a camera at him - which is why I hid behind the scales when he was weighing stuff out!


My next port of call yesterday was the camera shop, one of a small but growing local chain. As with the tackle shop it survives by providing good service and competitive, if not the lowest, prices. The reason for my visit was to return something which hadn't lived up to expectations - and wasn't suitable for one of its uses (although not a use I'd be likely to put it to very often, if at all). There was no quibble over the refund. Then I asked i I could look at a lens, making it plain I wasn't buying. True to form the manager saw the potential for a sale and  told me she had the display/rental lens on offer...

Since I've been using the G2 with the 14mm lens attached a lot of the time I've come to see the world with that perspective: finding it not much different to that of the 35mm which has become my 'standard' lens on 'full frame'. So it was I clicked the 28 onto may camera. The new lenses might be bigger and bulkier than their older counterparts, but they focus snappily and quietly, and they don'[t weigh much either. Some gear snobs will decry their plastic outer construction, but both fishing tackle and cameras have taught me over the last thirty years to forget the idea that plastics are fragile.

I remember a Canon film camera bouncing off a concrete paving flag shortly after I had bought it with just a scratch. It was still in perfect working order many years later after rattling around in my rucksack. Where plastics flex, metals either crack or deform permanently. To discount a lens on the basis that it's cased in plastic is plain stupid. The rigidity for keeping the important bits, the lens elements, in alignment is just as good with plastics as it is with metals too. Give me a light weight lens over a heavy one every time.

What I wanted to check out in the lens was it's weight as much as it's performance. It certainly was light enough, even if a little bulky, but with a 1.8 aperture it was never going to be tiny. Sharpness doesn't bother me. Despite all the crap I've read about lenses on t'internet I've yet to buy one that hasn't been sharp enough for me, or one that hasn't focussed accurately. Judging by the comments on forums I must be really, really, lucky. Sure I get shots where focus is off, but it's down to the autofocus system, not the lens. Sometimes even a good autofocus cocks up. The lens I was looking at supposedly has a 'focus issue'. Well it managed okay for me.

Another thing I wanted to check out was how close it focuses. Reading what the minimum focus distance is isn't the same as poking a camera at something close up. The real world test shows you how much of the background is included in a shot. This test was passed.


More importantly than being sharp the test shots 'looked' good. I guess it's a combination of contrast and out of focus rendering (bouquet or whatever the nerds call it...) plus the colours a lens produces - Sigmas are definitely different to Nikons in colour rendition . The overall 'look' of the shots seemed fine to me. It would be a great lens to use in the tackle shop!


Of course I don't need this lens. I'm certainly not considering purchasing it. Not until I've offloaded a couple of my existing lenses at any rate. It appeals to my urge to pare things down - heading back to the meagre selection of lenses I had for my Pentax ME: 28mm, 50mm, 100mm. I wonder if that's nostalgia or logic?

Geeks

One of the currently hot topics among camera freaks on the forums is the effect Nikon's new 36mp  sensor in the D800 will have on people's ability to get sharp, hand-held, pictures. More pixels in the same space magnifies camera shake. Apparently. I know I said I'd had enough of camera talk, but I stumbled upon something that made me chuckle today:

There's a serious amount of resolving power in this camera, though not quite at the D* level. Still, some folk are actually going to have a difficult time with the D*** because of that. What do I mean by that? You need to watch for mirror vibration, wind vibration, sloppy hand-holding techniques, and be using excellent quality lenses or else you'll find that you don't get "sharp" images.

That's pretty much what is being said about the D3 and the D800 today, so why the amusement? If you click here it might become clear...

Firefox

Nothing to do with photography really, but the Firefox browser has just been updated. Immediately I noticed that right clicking on an image to view it centres the image in the window on a mid-grey background. Small things like this make me happy.

With this new feature and the FxIF add-on for spying on people's EXIF info I'm a happy picture peeper!
