GH5 Speedbooster wide angle options for GH5

I recently had my camera bag stolen, and in it was my Laowa 7.5mm lens that I use for the occasional real estate shoot. I recently repurchased a gh5, but this time I also purchased a .64x speedbooster with it.

Now I’m wondering if I should drop 400+ on the laowa again, or maybe look into something a little bit cheaper for Nikon. I also liked the Laowa but I wasn’t necessarily wowed by it.

It seems like 12mm would be the sweet spot I’m looking for (24 x .64 = 15.36)

There seems to be a few options available for APS-C Nikon cameras, but I’m worried about vignetting on the wide end. I’m interested in the tokina 11-16, but have heard that there is vignetting all the way up to 13 with the .64x speedbooster which worries me. Maybe the tamron 10-24 could be pushed up to 12mm without vig? Any other suggestions for lenses under 400ish?

Just wondering if anyone here has any experience with wide angles on the .64x speedbooster

Thanks for any input!
 
Its the stigma 18-35

My experience of GH is that there is a difference with height with the bottom vs speedbooster. Once I have the speed booster on and a shim under the GH it is there for the day, so even though I have and old slr magic 12mm I never use it as i go nikon all day with the camera.
 
The 18-35 is a great lens for sure but certainly not wide enough for real estate use. @cinebren I'm assuming you bought the EF mount metabones? I have the 11-16 (.71x adapter) and there's no vignetting but maybe look at the Tokina 12-24 since it's designed for full frame use?

Yes you’re right, 18mm would be around 23mm with the booster, which isn’t wide enough for real estate.
I’ve got the Nikon mount .64x booster.
I hadn’t seen that tokina until now, not a big fan of the f4 but that might work for me.
Thanks for the suggestion!
 
F4 isn't ideal but remember the speedbooster brings it up to f2.8 (which yes is still shy of the 2.0 of the laowa but easily manageable IMO)
 
I love the Laowa 12mm zero-d. It really does come close (not quite) to no distortion and it's full-frame. I still have the Tokina 11-16 BUT the distortion at 11mm was quite noticeable AND the lens covered full-frame at 16mm but not at 11mm. So it might vignette on the .64x speesbooster? The only downside to the Laowa 12 is that it's $1k, but it's well worth it and you can use it on future FF cameras.

Laowa makes a 9mm zero-d lens for MFT mount for $500. That might be the best ticket in your price range. MFT lenses are cheaper than FF. The Laowa 7.5mm is not part of their Zero-Distortion line, so I'm sure the 9mm has less distortion. Plus, it actually covers APS-C, so you'd be cropping out the corners and any vignette or distortion there if any.
 
So I have the Tokina 11-16 in Nikon but I have the Metabones .64x in canon EF Mount. I went ahead and threw an adapter on my 11-16 and mounted that to the speedbooster and it does in fact vignette heavily at anything but 16.

I put my nikon 12-24 on and it vignettes significantly less at 12mm but it's still prevalent until 15mm.

If I was in your shoes I would either repurchase one of the Laowa options or save up for something else.
 
I've never had an issue with the .64 booster (mine is also Nikon)...yes it is wider than the Ultra but when you zoom till the vignette is gone, you're at the same FOV...if you find objectionable distortion on the 64 (I don't and use it for wide establishing shots or when I need really wide with the Tokina 11-16). The Tokina is a great price and I own the 28-70 too, as well as 3 Nikon 2.8 ED zooms and love the combo of both lens makers with the .64 booster! There's a previous thread on this topic somewhere and many on that thread preferred the Ultra...so you can search that thread too.

How far do you have to zoom in with the tokina and .64x combo before there is no vignetting?
 
If I put the tokina 11-16 on a FF camera, I can basically fill 16:9 at 14mm. Maybe there's a little shading in the corners, and I can't speak for filling the full frame height for stills.
 
If I want to go that wide I use it at 13mm on the GH5...for me that's very wide...I only shoot exteriors or certain interiors at that width and they are locked off shots....that's the equivalent of the Panny/Leica 8mm zoom which I nearly bought, but then decided after testing the Tokina I'm happy with it...I would however recommend you do your own test if you're considering going this way...you may not be happy with the results....it's also not a very sharp lens which you may want. I'm happy with the 11-16, but it's so wide I rarely use it!
