What macro lens focal length?
I would like to try some macro photography with a digital SLR camera has a sensor APS-C size (eg, a Pentax K100D). If I had to buy a macro lens first, how do I choose between 50mm and 100mm macro? Or maybe a macro 70 mm? I understand the basic principles of focal lengths, but how is the impact of focal length of macro photography? The lenses all seem to increase 1:1 distance and focus distance is not too different.
You're right. The glasses will all work for macro photography. The first consideration The lens is no longer impose or permit – depending on your priorities – greater working distance. If you plan to shoot live animals and insects, the gap will be more work less intrusive. You will not scare the insects or vermin there. If people are taking photographs of actors, such as eyes or teeth, some people may prefer to have a little farther then 100 mm. If outside, his shadow will be less of a problem with the lens more. You have a short range of the discussion with longer target. This can be an asset or a problem, depending on what you photograph. One advantage of the smaller target is that it costs less money. For Pentax, I see it is around the $ 100 price difference of 50 mm to 100 mm. I also see a 70 mm Sigma, which falls right between the two Pentax lenses price, but I see that offers all the advantages, particularly given that the minimum aperture is f/22 on Sigma Pentax and the two go af/32. When you get a 1:1 playback, you may only f/32 want the ability to increase depth of field. Personally, I bought a 60mm Nikon f/2.8 and I admit that this is partly due to the cost of 60 mm and cost $ 400 of the 105 mm approximately $ 600. Therefore, the objective is 60 mm translated by an effective 90 mm long and is "classic" for portraits. I can not find Non-105mm VR, but I see that the cost of 105 mm VR macro lens $ 800. Man, I think he was tempted by the RV, but I doubt it. See, you're lucky. You "Shake Reduction" integrated camera boys Nikon and we have to buy the lens … Anyway, he asked what goal to buy. I Skip the 70mm because it offers no price advantage and do not stop so as Pentax lenses. After that, I'd say it's easier to hold the 60 mm even if you do not use a tripod, but his experience with vibration reduction might have to go ahead and buy 100 mm anyway. Remember that you can use a normal lens to photograph well, in order to decide whether to have a 60mm (equiv mm to 90 mm) or 100 (equivalent to 150 mm) fixed focus lens and buy this angle. 90 mm is in the range "classical" portrait for his work in the distance and perspective, if that matters to you. I see it is delivered to a manufacturer that continues until March 27. Gets a dollar per millimeter – $ 50 on the 50mm lens and $ 100 in the lens of 100 mm. Make sure your dealer provides such reimbursement.
