Does exist a TTL converter for Inon Z240? I mean not using optical fiber but only the sync cord. Anyone has tried the Sea&Sea TTL converter with Inon?

I think you are having a misunderstanding because the Inon Z240 does not work in TTL with the D200 whatever the setting. You would need a TTL converter or shooting through optical fiber in order to have TTL.

Thank you very much for your advice, I've made up my mind, I'll go with Sigma....ByeAndrea

On film I always used the Nikon 16mm FE (then went to digital DX Nikons), but when I first started shooting FX Nikons, first with the D3 and then D700 as my main camera I used the Sigma 15mm most. But in the last few years I have been using the Nikon 16mm more - I think because I have noticed things it does slightly better. However if I didn't own both I'd have never have noticed. I always choose the Sigma if close focus is important, but for wrecks and big scenes (e.g. Iceland) I tend to use the Nikon.

Looking at my Lightroom Catalogue of "keepers" and comparing the percentage between the two fisheyes is interesting. In the first years of FX I used the Sigma most, but the percentage has reduced consistently over time, partly driven by what I have been shooting too and a move away from CFWA to more standard WA. But I find the trend interesting and worth sharing.

Percentages of use of two fisheyes (judged from images kept, not taken)

All years shooting FX: Sigma 15mm 57%, Nikon 16mm 43%

2008 (D3 mainly): Sigma 15mm 84%, Nikon 16mm 16%
2009 (D700 mainly): Sigma 15mm 72%, Nikon 16mm 28%
2010 (D700 mainly): Sigma 15mm 66%, Nikon 16mm 34%
2011 (D700 mainly): Sigma 15mm 38%, Nikon 16mm 62%
2012 (D700/D4): Sigma 15mm 11%, Nikon 16mm 89% - data unreliable as only 4 trips so far and not yet edited.

I post this for interest, really. Buy the Sigma! Just perhaps not in Italy.

Hai Fred, just a question about your fish/eyeIs it better the Nikon or the Sigma one? And Why?Here in Italy in shops the Nikon costs about 980€ and the Sigma about 660€.... For this difference in price witch do you suggest to buy?ThanksAndrea

I use my 16-35mm lens far more than I use the full-frame fisheye lenses I have - Nikon 16mm f2.8 & Sigma15mm f2.8. I don't particularly like the barrel curve effect of the fisheye lenses and now mostly use the Sigma lens with a very small dome port. I try not to use teleconverters at all because I am not happy with the sharpness loss they cause, particularly when used with a wide-angle lens which is not what teleconverters were designed to work with in the first place. I like to make large prints - normally 16" x 24" - and rarely does a teleconverter provide the level of sharpness I can accept. If what you do with your pictures is usually post them on the internet at 72 dpi then using a TC is probably OK for your particular use.

Ok , I'll go with the original Nikon one then.So do you prefer ~180mm(1.7x) over ~150mm(1,4x)?ThanksAndrea

I use the Nikon 1.7x AFS with the 105mm and it is a different world from a Kenko in AF speed and image quality. But it is a TC that I own primarily for use with topside telephotos.

Hello,
I'm very interested in the HW TTL converter for InonZ240...
Where did you buy it?
Thank
