This depends on what camera you're using. Wats the maximum focal length of your cam's lens?
E.g., Having a +10 on a G2 (102mm) will give you smaller magnification compared to using a +4 on a C730 (380mm).
Let us know your camera model so that we can advise you accordingly. And also what type of insects are you interested to take? Taking butterflies and bees, for example, require lens/filters with different diopter ratings.
Ok, now we know more abt your equipments and expectations.
A40 has a maximum focal length of 105mm. If you wish to take a range of insects, then my advice is you'll need both a +4 and +10. +10 can be used for taking bees, grasshoppers, flies, etc. A +4 will be just nice to take dragonflies and butterflies.
I agree with azone. Get the cheaper HOYA +4 closeup filter and try 1st. Practise until u master the skill of macro shots, then it is the time to improve ur image quality by replacing to double element closeup lens ...
The limitations of A40 will probably be the following:
1) Limited manual settings (aperture values quite limited in range if i rem)
2) No flash hotshoe for external flash
3) 3x zoom only
I would agree that A40 might not be able to meet your expectations if your expectations are very high. So dats why i suggested getting the cheap HOYAs to try out. IMO, getting the T4 is not exactly neccesary for you yet.
Originally posted by Wryer 1) Yep, the manual features are rather limited. azone, i notice that u use pretty small apertures like f8 or 11. I thought i should use bigger ones like f3.2 or 2.8 to get the background blur?
2) I thought of using slave flashes but...haven quite research on it yet.
3) Yup, the 3x zoom is pretty limited. So ive gotten myself a TC to extend it to 6x!:devil:
Btw, for macro shots, should we zoom all the way out and use a closeup filter/lens?
Yes, for tiny insects, i need to use small apertures to get the insect as much in focus as possible. In high magnification, the background is easily blurred even when using small apertures. For taking butterflies, its a different story. A large aperture is used instead coz butterflies are thin.
Fo A40, i guess you may need a flash bracket to mount a flash. But not sure if A40 has a flash sync outlet for external flash.
When using them, you'll need to zoom in to see the effect. Using one at wide angle is as good as not using one.
