bad lenses or bad setup?

[mikeboy]

hi guys, I just bought a 0.5X macro and 0.42x fisheye lens for my Panasonic Lumix FZ-50 and well, I am very very dissapointed with them.

With the macro I get very blured shots near the edges and the fisheye, well, its a curcular photo that takes up about 40% of the picture. I have black corners and basically very bad quality.

I know, its not a d-slr camera... but still, its a 500$ top of the line digital camera... :confused:

here is an example:

Is this normal? bad lenses?

Try taking your aperture down a few stops.

Does seem pretty blurry around the edges. What lenses are you using?

My guess is that's normal. Adapters aren't known for high quality, and even on an SLR, you use teleconverters judiciously. Fisheyes are extreme lenses--they do a serious amount of light-bending at the edges to get the wide field of view, so along with the warping and distortion, you'll often get vignetting (darkness at the corners), blurriness, and chromatic aberration. I use a $600 circular 8mm fisheye lens regularly, and it still exhibits blurriness and CA at the edges and creates a circular image that doesn't use the full frame.

sorry for late reply, thanks to all for your input.

@saralonde: these are the lenses:
0.42X FISHEYE MACRO FOR PANASONIC LUMIX DMC-FZ30 FZ30K FZ50 (http://www.amazon.com/gp/product/B000FZ2UYY/002-0631838-9152005)
0.5X WIDE ANGLE LENS+MACRO FOR PANASONIC LUMIX DMC-FZ30 FZ50 (http://www.amazon.com/gp/product/B000G2NKBI/002-0631838-9152005)

Well, the fisheye is not that bad, the picture above, that was the macro lens alone, the fisheye does something like this:

then I took the 0.5x macro from the macro lens and replaced the 0.42x from the fisheye with it, and got something like this:

those I think are not so bad, but...

you get what you ay for I guess... :(

that's right, this sort of problem is common with those inexpensive ebay adapters. i'm guessing that shot was taken as wide as possible. in order to have the corners properly focused and not blacked out, zoom in a bit until their gone.
the camera was designed using the stock housing and lens configuration. when you're adding attachments onto it that the manufacturer did not intend to be added, of course problems can occur. had the same problem with a wide angle adapter i used on an old canon S3. in my opinion, they're pretty worthless and hurt the image quality more than they help. if i were you, i'd toss it.

yeah, Im just going to forget about them, besides, I've been so cought up with lenses and macros, etc that I am not focussing on the picture itself, I find that my new photos are much worse than the ones before, so, Im going back to basics.
