Used animal eye focusing with new to me Sigma 135mm f1.8 at f1.8 on the neighbours dog Minnie. This was taken from over the adjoining 5 foot fence and is heavily cropped. The eye af worked ...

Just a point regarding the Samyang 135mm. Although the nikon f version has a chip which functions with dslr bodies such as D500, D800 etc to allow the camera body to control the aperture and other ...

Unfortunately your experience with the 50mm f1.4 art mirrors what I obtained with the sigma 85mm f1.4 Ex DG (pre art series) on the D700 several years ago. I was lucky to obtain  a couple of ...

Macro lenses usually have a very long throw so not sure to what degree the Techart adapter is going to autofocus. If you are interested in a manual focus Zeiss macro you might also consider the ...

Not sure why you would need to revert the focus adjustment back to original settings for the Z camera. Surely there will be variance in focus between lenses straight out of the factory and the ...

Hi Tord, just noticed your request for the names of the birds I previously posted. 1st and last I believe is a young robin 2nd a Dunnock 3rd male Chaffinch 4th male House Sparrow David

As previously stated I consider my copy of the sigma to be sharper than the nikon. Below are two photos which I have taken at different times but with similar but not identical settings. These ...

I use the Gabale L bracket on the Z7. Good fit and finish, the allen key stores magnetically in the base, and much less expensive than rrs etc. I believe mine was about £22 when purchased probably ...

The weight of the 300pf + tc is about 200gm less that of the sigma 100-400mm and at 400mm the aperture f5.6 vs f6.3. The sigma has the advantage of zoom. In my case the sigma is sharper than the ...

Just a note on collars. I have the ishoot model. It does not allow the lens to rotate on the collar, thus if you wish to operate in portrait mode the rotation will have to be performed on the ...

Must agree, this is a great lens for the money.

I have a similar experience. Purchased the sigma earlier this year and it has never been off the D500 body. Must get round to selling the 300pf.

Never had the art lens only the Ex Dg. Used on nikon cameras (D800, D700). Image quality I considered very good but focus attrocious. Tried two copies of the lens and in the end gave it up as a ...

Hi Peter, I purchased a used sigma 100-400mm during March of this year. I have the nikon 300mm pf but since the puchase of the sigma it has seen little use. The photographs I have taken have been ...

Three photos from today. All garden birds taken with the Z7+FTZ+Sigma 100-400mm

Starling on feeder support taken with the Z7 in FX mode +FTZ+Sigma 100-400mm

As I said previously I can only indicate my experience with the lenses and tcs I own or have owned. I did not consider the 2x converter when fitted to either the 70-200 f2.8 VRii or the 300mm f4 ...

Cannot speak for the tamron, but the sigma works well. I have used it on a Z7 and D500 and find it equally satisfying on both bodies. Below are a few examples with the Z7.

I have the nikon 70-200mm vrii plus the 1.7 tc. I have used this combination in the past with a D800 and obtained good results at close distances. I tried the tc2x version iii but was not ...
