HV20 and Sony wide angle Lens tests
 
I've just been trying my HV20 with a Sony VCL-MHG07 wide-angle lens (using a 43-52mm step up ring).

Here are some screenshots:

you may want to repost those images, you didn't use the correct links, those are just mini thumnails, way to small to see any detail

Hey Fergus...many thanks for posting these. I'm very impressed with the images taken with the Sony lens and think I'll look into getting one as well...unless others have a better alternative for a same-priced lens.

Jay

Just left click on each thumnail and it will hyperlink to the full size image

Nathan, thanks - I think the results are pretty good. My main concern was sharpness but I am satisfied with that. I have posted the raw footage on another forum (not sure I can link from here)

Nathan Shane July 10th, 2007 09:24 AM

Have you tried any closeups with wideangle lens?

Fergus Anderson July 10th, 2007 09:29 AM

No not yet, just got my step up ring today. Any particular scenario you would like to see?

Chris Barcellos July 10th, 2007 09:38 AM

I have had some pleasing results with a Kenko .7 wide I have used on my VX2000 for years. I use a 43mm to 58mm step down to match it. I will try to post some stills tonight. Being designed for SD, it still seems to provide a decent picture for a wide angle shot. It does appear to soften the image a bit, but that is not all bad, in terms of filmic qualities.

I also use a 58mm Sony 1.7 teleextender on the other end, again originally purchased for the VX2000. CA is a big problem at the extreme end of the telephoto range with that lens.

Hmm...perhaps something that has a primary character dog/cat/fire-hydrant/mailbox ??? and a couple other interesting subjects further away (but not far away) in the background. I guess I'd like to see some DOF and how closer subjects actually look in comparison to that which is behind/around them. And pick some odd angles to capture from to help exaggerate the perspective somewhat. And maybe primary subject is drastically different in color(s) compared to background secondary subjects. Okay...that's a lot to ask for. Just do whatever you feel like doing. LOL!!!

Fergus Anderson July 10th, 2007 01:48 PM

Ok here are a few closeup shots with the Sony lens

If you would like the footage just give me a PM since its on another forum and I dont think Chris would like me to link to it. I think on the whole the images are very sharp closeup. The camera in normal autofocus does take a while to focus if the position of the subject changes quickly. Sorry for the lack of imagination with the shots, only had a few minutes in between changing baby!

Let me know what you think
Cheers
Ferg

I always reckon it's barrel distortion that spoils many a wide-angle converter, and door frames that bow outwards as you track room to room look horribly amateurish in my book. None of the posted images show straight lines that don't pass through the middle of the frame, and this is the great barrelling test.

Nathan Shane July 10th, 2007 02:17 PM

I like the next to last image with the garden tool best...it shows the depth I was curious about. And the one with the green leaf, I like that as well. Thanks! You've shown me what I was wanting to see.

Tom, sorry what would you like me to shoot? Door frames at the edge of the picture to test how straight they are?

Cheers

Tom:

I think the HV20 at the wide angle range has a about the equivalent of a 32 mm 35mm SLR lens. So if you slap a .7 on that end, are you enevitably doomed to seeing barrelling ?

For your comparison, here are jpegs of Shots with my HV20 with the Kenko Pro 65 which is a .65 x, not .7. All shots were at widest angle setting.

Lens is Kenko KRW-065 Pro II 0.65x

Fergus Anderson July 11th, 2007 05:23 AM

nice shots Chris, it does look a little wider than mine.
