I am gladly giving a chance to test the newer Fujifilm camera XT4 to capture pictures and videos using either

A. FUJINON XF200mmF2 R LM OIS WR

B. FUJINON XF100-400mmF4.5-5.6 R LM OIS WR

C. XF70-300mmF4-5.6 R LM OIS WR (New)

another special test on XF70-300mm

600mm setup… only ~1.4KG ! Fujifilm XF70-300 | liewwk Nature

 

I will slowly update some of my concern features which related to Tropical forest birding requirement e.g. ISO performance (we have many lowlight condition environment), lowlight Autofocus, Image Stabiliser (handheld shooting minimum shutter speed)

– Testing 1a: Image Quality FujinonXF100-400mm

– test this handheld with a various shutter speed

update 202103

– another good moment with this active bird

– 非常活躍的鳥。他在看我在做什麼。

update 202103

– one of the world’s smallest woodpecker

– making loud high pitch call and drum sound

– 世界上最小的啄木鳥之一。可是非常大的啄木聲。

update 202102

– a beautiful Paradise-Flycatcher, male with long-tail and come either white-morph or rufous-morph

– this is a beautiful male passing with another male (not full tail and another female

– they make a lot of noise when moving inside the forest

– 馬來西亞非常漂亮的鳥。他與其他兩只一起追逐也叫很多。

Testing 1: Image Quality FujinonXF100-400mm + 1.4x teleconverter

– with the longest focal length 400mm with 1.5x crop (crop body) it is equivalent to 600mm 35mm focal length. So this may be a major concern for birding where 600mm is the maximum reach and always too short.

So I am trying to shoot this lens with 1.4x tc, which gives 400mmx1.4x=560mm and this equivalent 560mmx1.5=840mm (35mm focal length equivalent)

Testing 2: Handheld Video

– a must test for me, as my job most of the time I can’t carry 2 tripods (one for spotting scope). So my camera 100% using handheld when I am working.

– all videos share here are captured handheld

update 202102

– lucky moment to meet 3 of this beautiful Paradise-Flycatcher

– they make a lot of noise while moving around

– 幸運遇上3只這麼漂亮的壽帶 – 很吵，一直都跳不停。

Zone AutoFocus - can see with the lowlight condition and mess environment the Autofocus will trying to confuse by the nearby moving objects (eg leaf)

################################################

Testing 3: Continuous Focus Tracking

– a test I am using mainly to test Bird in flight

– Continuous Focus, Zone

update 202102

– another good moment before last light the bird just flying out from roosting

– the fast focus lock of the X-T4 and tracking make me able to have many keepers of this bird flying just in short distance

– 這鳥在天黑前突然飛出來。X-T4  對焦很快與準。

#

update 202101


- another day testing with X-T4 and 200mmF2


- mainly trying on AF lock speed and tracking for raptors 
flying


- and this is an example using AF Zone in Video record 4k, 
60p

 

update 202101

- lucky to encounter this bird, but it flies away immediately found I get close to it... 

- with the Fujifim X-T4 fast AF I managed to capture the 
flying moment 

 

 

update 20210114

– very strong wind day, there are Barn Swallow, Pacific Swallow, House Swift, Silver-rumped Needletail, German’s Swiftlet, etc flying fast near the water dam.

– I mainly want to try the focus locking speed and tracking speed for the X-system

Testing 4: Slow motion video 240p feature

– it is not really testing but rather a feature

– with the 240 fps, this gives a good way to present the object in slow motion

– the movie is smooth

update 202101

Fujifilm X-T4
