From the first time I started to shoot with Fuji gear, as nature photographer I keep eye on all longer focal lengths X system offers. Recently I recently had the opportunity to test Fujinon XF50-140mm with XF1,4× teleconverter.
I have to say I don’t like teleconverters much. I owned three of them from different manufacturers earlier and I tested few more, always with proffesional lenses (70-200 mm f/2,8 and 300 mm f/2,8). I sold all of them, because I was not satisfied with optical quality. The main reason was loss of sharpness when shooting from longer distance. While pictures taken from short distance was great, so it was perfectly acceptable for shooting small birds etc., distances over 10 meters shown lack of sharpnes in fine structures like animals fur.
I didn’t expect too much from XF1,4×, but I was pleasantly surprised. Neither this combo doesn’t avoid the described issue, but there are still lot of details in fine structures, which can be restored using appropriate tools in postproduction without leading to unwanted artifacts. Test shots were sharpened using Structure parameter in Capture One a for my comparison in Output Sharpener from Nik plugins collection, which I started to experiment with recently. Let’s go on sample photos – I never liked to shoot some kind of test patterns in lab conditions, so these are just photos from my normal shooting and were taken using different exposure parameters.
West Caucasian Tur – shoot from a distance of about 16 meters
Northern River Otter – shoot from a distance of about 6 meters
Black-tailed Prairie Dog – shoot from a distance of about 3 meters
House Sparrow – shoot from a distance of about 2,5 meters
Cuban Ground Iguana – shoot from a distance of about 1,5 meters
All photos was shoot with X-T1 body. I didn’t notice any issues with focus accuracy or speed using this converter. I didn’t test XF1.4× with other lenses, but it is very viable option for longer focal lengths on Fujifilm X system in combo with Fujinon XF50-140.
Lens and teleconverter was lend me by FUJIFILM Europe GmbH.
