The short answer is that there's no such thing as "should" in photography. Reality is that your camera (usually) gives you two output formats (sometimes three), and there is really no reason why you must forbid yourself to use one or the other. I hope that takes care of the "should" part. Now, which one do you want or need is up to you and your particular shooting style. In this post, I will try to enumerate the key points regarding the raw file format, and what it brings to the table.
If you've got some non-macro lenses and you want to get started with macro photography, macro extension tubes are one of the first options that are recommended. But how close can you get with extension tubes? Does it affect image quality? How well does the autofocus work with them? What do you get and what do you lose?
Usually when the words monopod and macro appear in the same sentence, it's snowing in Sahara. Hand-holding the camera is much less hassle, and the stability gained from putting the camera on the monopod does not offer much improvement over simply bracing against a solid object or a stick. This is why, after a few short trials, my monopod was left to collect dust for a few months... until a month ago.
Raynox has made its name among macro photographers with their excellent DCR-150 and DCR-250 diopter lenses. While the diopter lenses are generally the easiest and most convenient way to convert a non-macro lens into a macro lens, their optical quality is typically not that great. Raynox is an exception. In this post, we'll take a look at both the DCR-150 and DCR-250 diopters, and see how they are used and what kind of results they yield.
Crop factor is not something that was introduced with the digital cameras. It has existed for decades, since the inception of photography in fact. One would think that crop factor would be a well-understood topic by now, but it does not seem to be that way. In fact, even though I've shot film (35mm), I found myself constantly confused by the discussions about the crop-factor. Of course, digital also added a few of its authentic factors to the discussion, leading to even more confusion. In this post, I will try to summarize my views, and attempt to contribute some clarity on the topic.
