Close-up filter for Sony F717

I may buy a close-up filter for my new F717. As I know, Canon 250d 58mm and 500d 58mm are great. For the F717 lens with 38mm to 200mm, which one can get the better result and what is the different of them? Besides, is there any other recommendations apart from these two?

Moreover, I have a fundamental question to ask. What is the different between using teleconvertor lens and close-up filter?

Thanks for your contribution!

Thanks.

Ronald.

don't know the specific answer but saw some discussions in the past on the subject.

Did you try a search ?

Its called a close up, or macro, lens, depending on how much diopters it has, 0.25-5 is called close up lens and 10 or higher is a macro lens. Both canons close up lenses are not that strong, the 500D has 1 diopter and the 250D 2 diopters.

With the 500D you will be able to get as close as 45cm at full Zoom, the 250D allows you to get as close as 32cm, without those at full zoom the F717 can only focus at 90cm.

A close up lens reduces the distance the camera can focus at, a teleconverter enlarges the image.

If you want to do the calculations yourself, here are the formulas :

First you need to is divide 1 with focal length : 1/190mm=1.111

Second divide 1 with the above number plus the diopters of the close up lens in brackets : 1/(1.111+2 dpt)=0,32m or 32cm.
The same formula without closeup lens is 1/1.111=0,90m or 90cm.

I am using a B+W NL2 (2 dpt) and a Leitz (Leica) Elpro 2 (4,92 dpt) Lens. The second allows me to get as close as 16,5 cm at full Zoom, giving me the same size i could achieve at 2cm at wide angle, thats important for shooting insects or for better lighting, at 2cm the big lens usually cast shadows.

There are disadvantages however, more diopters mean less DOF and your image gets blurry to the corners.

Note that for the last link, Pondria used a lower grade single-element CU lens for the sample images. He later adopted the achromatic dual-element 500D.

When considering these things, how close you can get is not the main issue, and too close can be a pain especially with lighting. Your primary interest should be in terms of subject coverage (width and height), with the shooting distance at which that can be achieved coming next.

Thanks for the helpful post. Minor clarification below...

This might have just been a typo, but I think you meant to divide by the minimum focus distance at the focal length. At 190mm, the minimum focal distance is 90cm or 0.90m, so 1/0.90m = 1.111.
