    Want to go wider than 14, on a budget. Any thoughts on the 7.5mm de-fished versus the DMC-GWC1 on a Pana 14?

    Thanks in advance!

    De-fishing and IQ

    How much IQ is lost, if any, when you de-fish a fisheye lense?

    For the final image, I think the 14 + DMC-GWC1. IMO it better to start off with an UWA file than de-fishing. On the other hand you may loose an f/stop using the DMC-GWC1.

    Get the Samyang, it is wider, significantly wider, than my 7-14. Level shooting really helps minimize the harm done by defish. If you don't like the Samyang, I'll buy it.

    Here is an example of Samyang 7.5 defish. I have used this profile Rokinon/Samyang 7.5 Lens Profiles: Micro Four Thirds Talk Forum: Digital Photography Review in LR4.

    As you can see you lose little image quality in the sides of the of the picture.

    P1050539-Edit.

    This is a great lens and if you follow Gary advice to keep the horizon level in a lot of cases you do not need to defish like the examples below.
    You need also to keep straight lines in the center of the frame going to the center.

    This one is with tilt lens filter in LR4.

    Samyang definitely.

    It's sharp
    It's well build
    It's well priced
    And it's fun!

    I have both 14/2.5 and Samy7.5. Usually when I need to go wider than 14mm then 11mm achieved with DMC-GWC1 simply won't be sufficient and Fish eye is just right to have everything in image on tight places. I have never understand why should I defish fish-eye lens :confused: instead I am trying to utilize distorted perspective in creative way and Samy7.5 is pure fun when used as point and shoot style similar to Lomography :thumbup:

    Yes it is fully manual lens, no electric contacts, no information sent to camera. But huge DOF is making it set and forget lens ;)

    More like pre-set and forget, infinity and three feet are so close that there isn't much turning of the focus ring. I'm definitely gonna get one, a fun lens like a LensBaby.

    Hi Gary,

    Thanks for the input. When you say the Samyang is significantly wider, are you saying that after defishing, you still have a wider angle of view than the 7-14mm at 7mm?

    Thanks.

    The research was done, look at the link bellow, this guy convinced me to buy the Samyang.
