The Battle Of Super Telezoom

Sigma & Tamron 150-600mm Super Telezoom

Sigma & Tamron 150-600mm Super Telezooms

Sigma has just announced it’s new, not one but two, super telezooms, the 150-600mm F/5-6.3 DG OS HSM Sports and the 150-600mm F/5-6.3 DG OS HSM Contemporary .  It has been expected that Sigma will come out with a version to rival the Tamron SP 150-600mm F/5-6.3 Di VC USD, and now we know it come with a little surprise.  The sports version is the bigger brother, heavier, more elements and a huge filter size of 105mm but the contemporary version is packaged quite similar to the one offered by Tamron, except that the weight is yet to be announced.  We will see what will the pricing be.

What I like about the Sigmas is that they have vertical stabilisation which makes panning a piece of cake, while the Tamron doesn’t.  At least that is what I saw from the pics of the big brother here plus zoom range lock and focus limiter.  No doubt comparison will be made between the Sigmas and the lone Tamron and I am waiting for it.

Test Run The Sigma SD15

Sigma SD15 with 50mm f2.8 EX DG Macro Lens

I bought this camera with the intention to use it as a studio camera for portrait photography.  Since I am more of an old school photographer, I feel at ease with the Sigma SD15 though there are some noises in the net about it lacking some features found on other cameras.  What matter to me is the result.  I want to see if I can get to see again the sharpness like I used to when looking at the prints of the brides decades ago working part-time as a freelance wedding photographer.  So far I am still not satisfied with the results from my present gears.  Maybe it’s not the camera but the nut that holds the camera, but then it will still be the same nut that holds the Sigma SD15.

My original intention of matching the SD15 with Sigma 50mm f1.4 EX DG HSM was scrapped in favour of the Sigma 50mm f2.8 EX DG Macro because of the macro capability, cheaper and at f2.8 it is still not bad if the eyes aren’t failing.  The camera bought online because I could not get it locally.  It came with an 18-50mm f2.8-4.5 DC OS HSM kit lens.  This lens will be handy when I need to shoot wide but for now I am more concerned with the 50mm prime lens.  Since portrait shootings are mostly on the tall side, at least in my case, I had also bought the power grip PG-21.

While contemplating who shall be the test subject and waiting for the opportunity to come, I took some still shots of a pineapple.  Then about two weeks ago, I had visitors and it was just perfect.  I must say that I am quite happy with the results straight from the memory card.  Here are the still photograph of a pineapple and the portraiture of one of the visitors after some editing in Gimp and Faststone.

Update 16 Sep 2013

Well, I have cleaned the individual lenses in the Takumar 135mm f2.8 and took the liberty to cut the protruding aperture lever on the flange that prevented the lens to mount on the Sigma SD15 and took some shots with it.  Here’s one of them;

Why My Pictures Are Not Sharp?

Prophet Muhammad Birthday (pbuh).

The Foveon X3® Direct Image Sensor

It’s the sensor. The current sensor technology had it’s three primary colour pixels side-by-side as opposed to the film method of recording colour where it had the red, green and blue recording materials in separate layers. To make one dot or a pixel of colour in the sensor, it is spread a little bit and then manipulated. That is why the image is not as sharp as the image produced by the film. This belief is just my assumption.

Having bought a Sigma lens, I did have a look a its site and came to know of a new sensor technology called the Foveon X3® Direct Image Sensor. It was developed by Foveon, Inc. which was later bought by Sigma Corporation and became its subsidiary. Pictures look sharp and I had just bought a Canon 😦 . No wonder I did saw some serious photographers works quite a while back on the net using Sigma camera plus an adapter (or modified mount) and some very expensive prime lenses. It is only now that I know.

I sincerely hope that in the near future Canon will use such technology or its equivalent else I will be dreaming of a Sigma camera. It is the only dslr camera currently on the market that have this kind of sensor and please Sigma don’t slap a high price for it to let other camera makers to incorporate this sensor.
