PS at JPEg compression 11.. at 12 the filesize was too large for the image host.
http://img.photobucket.com/albums/v198/ ... 02crop.jpgThis is the sharpest image that I got.
Shutter speed: 1/500th
Focal Length: 220mm
Aperture: f/5 (I know this lens isn't sharp wide open but I needed the light)
The shot was taken on a velbon cx560 tripod and using the 2 second self timer so that I wasn't thumping down on the shutter, causing the vibration.
There you have it guys, how can I improve the technique to get this kind of shot sharper? I feel like I'll get better shots using my 50mm 1.8 lens instead.
Thanks,
Owen.
Dear Owen,
Excellent, you are using tripod and self timer to minimize camera shake and you did succeed. At 1/500, you don't need the tripod as your focal length is 220mm. With proper handholding, you can use 1/250 to 1/125 to get sharp pictures easily.
The problem is not of sharpness. You can overcome the problem by:-
1. Using a smaller aperture (f11 - f32). Try not use f32 if possible. Don't worry too much about shutter speed as you are using tripod as long as the speed is above 1/60.
2. Focus point. Your focus point should be on the insect's eyes.
3. Move closer to the insect/flower. Move a few cm and stop and do it again until you are about the minimum focusing distance that you lens can focus. You need more magnification of the insect or flower to help you achieve the desired point of focus.
4. You can always add a closeup filter (+4 or +6). Don't buy +8 or +10 as the higher they do, the more they degrade picture quality. This is a very cheap way to get more magnicafication (like a magnifying glass) for macro. Alternatively, you can buy an extension tube (also very cheap). An extension tube is a hollow connection between the camera body and lens. It allows you to move closer to the subject, thereby giving you more magnifcation. Extension Tube 25 is the way to go for starter.
5. Use flash. Buy SB-600. Use Manual
mode, dial shutter speed to 1/500, use f11 - f 16 and the camera and flash will work out the desired amount of flash to output. This is a good way to practice handholding.
I would encourage you to learn macro by using whatever equipment you have, slowly build up your understanding and macro techniques. Using close up filter, extension tubes and teleconverter will enrich your understanding of macro. Then when you finally get a macro lens, you will realize how much you have benefited from the experience.
When you get your macro lens, you still can attach those stuff that you buy (close up filter, extension tubes and teleconverter) to the macro lens to get higher than life-size magnification.
Finally, enjoy and have fun.
regards,
Arthur
