Nikkor 18-300mm Lens Field Test Results

I purchased the new Nikkor 18-300 mm (f/3.5-5.6) lens today and ran it through a bunch of test in various condition and the results are in… this is a great lens for $1,000 (US)! It maintains excellent sharpness even with shots done fully extended at 300mm, there is practically no darkening around the corner/edges, very low noise, and sharpness on close subjects is spectacular. Drawbacks… slight chromatic aberration on high contrast edges that are near the sides of the photo when shooting with... continue reading

First upload with 7D

Received my new 7D camera about a week ago now and I am using a sigma 50mm 1.4 lens on it at the moment. Saved a few hundred euros buying it online. Since I will be studying Film and Visual Image making soon, every saving counts. I am trying to build a film making/photography kit from scratch, on a truly tight budget! I had a lovely day out at the beach and took alot of informal portraits etc that unfortunately I cannot show here. The difference between the 7D and my old coolpix is astounding. The... continue reading

Interior photography

Well this article is for a newbies. If you have some information to fill up, I would be thankful.So what you need to interior photography? First of all your camera :) Then it is helpful to have lens at about 10-20mm angle diapason. If the room or hall is quite big, then it could be enough to have at about 30mm angle lens. But if you want to make photos of ordinary home interior, 10-20mm angle diapason is really helpful.I don't used any flash or other light apart from light that comes through... continue reading

Lesson number 2: The lens

Continuing on from my first post on camera bodies (camera bodies - lesson 1), here is a bit of extremely basic information on camera lenses, in plain, simple English. As before, I am writing this with novice photographers in mind; those who are new to the world of SLR and stock and want a bit of basic, easy to digest information.When I opened the box of my first SLR, I found a shiny 18-55mm lens sitting inside. I asked myself, ‘what does the 18 – 55mm actually mean?’Those values are... continue reading

New lens and hopefully some more pictures

I have been very quiet on the photography front for a few monhs, winter was brutal and cold and planting season is always very busy!However I have taken some of my macrostock earnings and invested in a couple of new lenses, the Tamron 17-50mm f.8 and the Sigma 50mm f2.8 Macro...I have reviewed the Sigma on my Website and have to admit to being incredibly impressed, I'm aware that macro images do not sell massively on stock but I love shooting iny things so it works for me and if I make a few... continue reading

Fisheye Fun in Florida

Before leaving on our spring break vacation to Florida, on kind of a whim after some of the Micro 4/3 banter on the Dreamstime blog, I bought myself a fisheye lens to bring along.Doesn't every photographer have a secret wish to use a fisheye lens at somepoint?There is something so exotic about that superwide effect.For most situations its not a very practical lens to use but for those special occasions it provides the perfect effect.Especially with interiors or when you need to get really... continue reading

Olympus 45mm f/1.8 lens review

I used to be seeking the perfect P&S - one that was good enough in quality to allow me to abandon the idea of carrying my dSLR for all but the most critical situations (naturally the dSLR is the first choice in the home or studio as weight and size are not factors).I've slowly come to the conclusion that there are too many disadvantages.It isn't that great shots can't be had from a small sensor camera with zoom, but the problem for me is that beyond scenics and travel photos,... continue reading

Lens for Micro 4/3 Cameras

Micro four thirds is a camera standard or design created via a partnership between Olympus and Panasonic.The design does away with the mirror and prism system found on traditional DSLRs so the result are very compact cameras.Camera mounts can be used to marry traditional or legacy lens to M4/3 cameras or of course the growing line of lens created for the M4/3 design are available from Olympus, Panasonic (with lens designed by Leica).One of the big advantages of the M4/3 camera is the compactness... continue reading
