One of the reasons to own 8k video most probably is to crop the video like this one to get more clarity (but I didn’t reduce it to 4k just want to show 8k video and zoom in)
let’s have a look at 4k and tell me how’s this video looks like? very good? good? normal?
I am glad to be given a chance to be tried on the Fujifilm XF70-300mmF4-5.6 R LM OIS WR. Even though we don’t have that many opportunities to do more tests on this setup because of the Covid-19 lockdown.
for quick sharing from Fujifilm XF70-300mmF4-5.6 R LM OIS WR Liew WK – Lens Stories
For birding Photography, we always concern about on few camera and lens specifications
1. Image Quality
– how sharp and how’s the ISO performance
– with Teleconverter Image quality
2. Autofocus performance
– how fast the autofocus, how accurate autofocus, and how good is the tracking capability
3. Weather-resistant, Weight and Size
– no one can deny bigger lens (longer and bigger aperture) will give you better image quality but we need to know how much we can tolerate with Image quality drop with the size and weight reduce.
– most of the bird photography here (Tropical rainforest – Malaysia) involves a lot of tracking, walking, hiking so it is not really a good choice to carry heavy equipment to long hours to do bird photography here.
Some Extra Features
4. Minimum Focus Distance
– most of the Bird photographers also a nature lover who may also capture many other creatures (butterfly, snake, etc
– minimum focus distance of 0.83 which give magnification 0.33
5. Image stabilization
– I can’t comment much as not really do a lot of testing on this but some of the dark conditions where I shoot ~600mm at 1/10-1/30s also give a very good success rate but for my comfort. 1/100 is a base shutter speed to get a very high success rate for myself.
I also captured some videos handheld
####
Very low light condition
ISO1600, F8.0, 1/30
################################################
1. Image Quality
– with previous testing on the Fujifilm equipments
– as previous testing share, the X-T4 AF performance FAST, accurate and tracking is good too.
– I won’t share any single point AF here as all others above are using AFS or single focus but here I am sharing what I am concern about continuous focus for both lock focus & tracking capability
– Both above Loglight Condition sharing pictures were captured in very low light condition and AF is still fast and accurate for AFS
All pictures below captured with AFC – continuous focus and Zone (almost full screen). [I let the camera and lens decide to lock the object and track without any additional setting change]
i. Terns
– many of them flying far and near with moderate speed but in any direction under the hot sun
– most of the focus can lock fast and continuous tracking the bird by the next 1-2 s as the tern fly out from the frame
– it is almost no fail to lock focus when the birds flying with blue/white sky and sea background which has enough contrast
– it is getting difficult to lock focus when a bird flies into the frame where the background is green
– this owl all of a sudden fly out from the small palm oil plantation- the focus lock fast but the tracking miss 50% intermittent as it is flying toward me fast and close (some of the focus frame lock on the wing but not the head).*** the tracking may able to improve by some AF setting. as the focus locking is fast enough to focus again after miss out of focus within 1-2s flying toward me seriesFujifilm X-T4, Fujifilm XF70300, TC 1.4x [434mm, ISO800 F.8.0 1/1250]
– This is a special case where this hornbill standing on a building wall. So make use of the continuous focus & tracking mode. Even the bird is near the tracking work since the bird begins flying until it missing into a tree.
– the moment happens just ~2s, while I am shooting 7fps. and the focus just miss 2 frame
– it is very difficult to capture swift picture due to normally they are flying fast, all different direction
– success rate is not very high due to the flying speed very fast and accelerates in any direction for feeding. But the camera and lens still able to lock the focus as long as my position is at the right position.
– due to the APS-C sensor size the lens design in a smaller size compared to an equivalent 35mm equivalent lens (100-400mm)
– the lens with X-T4 which is 607g (including battery and SD memory card)
– 1.4x TC
with such focal length 107mm to 457mm or (107mm to 457mm)x1.4 or x2)
look at the size
4. Minimum Focus Distance
– this lens can take a photo at a minimum focus distance of 0.83 which give magnification 0.33 think this is also good for some butterfly, big object macro
– Adobe Camera RAW 12.4, same recovery and other parameters for the same test
*** I found the Dynamic Range setting not just affect JPEG output, but also affects the data inside the RAW files. So testing also included DR100 (off), DR200 (suppose reserve highlight exposure 1 stop) & DR400 (suppose reserve highlight exposure 2 stop)
But check out the RAW files recovery result below !!! it is some magic that happens !!!
################################################
1. Highlight Recovery Test
1A. Highlight Recovery Test: Dynamic Range setting
– make sure of in Camera setting to protect Highlight details
Even with the direct JPEG output, the highlight details have been protected (DR200 1 stop and DR400 2 stops). But let’s have a look at the RAW file recovery
LEFT: DR100
CENTER: DR200
RIGHT: DR400
#
1B. Highlight Recovery Test: RAW files recovery
Test1: Highlight recovery from RAW files
– ISO1000, F5.6, 1/15 – this makes the picture +4 (4 stops overexpose)
– Adobe Camera Raw recovery. [Highlight -100%, Exposure -3.00]
#
Test1Bi. Highlight recovery, DR100 (DR off)
– All setting same as mentioned above
– DR100
– LEFT: Direct JPEG from Camera
CENTER: RAW
RIGHT: recovery setting as above and save as JPEG
#
Test1Bii. Highlight recovery, DR200
– All setting same as mentioned above
– DR200
– LEFT: Direct JPEG from Camera
CENTER: RAW
RIGHT: recovery setting as above and save as JPEG
#
Test1Bii. Highlight recovery, DR400
– All setting same as mentioned above
– DR400
– LEFT: Direct JPEG from Camera
CENTER: RAW
RIGHT: recovery setting as above and save as JPEG
#
Here’s come the magic of the RAW file and the Dynamic Range settings !!!!
– Look at the right face of the toy & background paper beg
– the DR400 not just protect highlight data in JPEG but in the RAW file, preserve more than what we expect (3 stops + 100% hight recovery)
DR400DR200DR100
#
2. Shadow Recovery Test
– 5 stops underexpose
– ISO800, F5.6, 1/8000
– DR100, 200, 400
– below are JPEG direct output from Camera
#
Test2A. Shadow recovery
Test1: Highlight recovery from RAW files
– ISO800, F5.6, 1/8000
– this makes the picture -5 (5 stops underexpose)
– Adobe Camera Raw recovery. [Exposure +5.00]
#
As the discussion of Dynamic Range is to protect Highlight data of the pictures. But I still go ahead with my test with DR100, 200 & 400
#
Test2Ai. Shadow recovery, DR100
Test2Ai. Shadow recovery, DR200
Test2Ai. Shadow recovery, DR400
#
For the 5 stops Shadow recovery, most of the details of the focused object still intact.
But when we turn on the Dynamic Range (DR200 & 400) gives an impact on the RAW files. Something really weird where DR400 actually give negative impact which produces more color noise and purple tint when exposure recovery
#
So we need 2 settings for Highlight & Shadow recovery
1. Highlight recovery: Highly recommend Turn on DR400
2. Shadow recovery: Highly recommended Turn of DR which is DR100
1. Greater Painted-Snipe, 彩鹬, 彩鷸, Rostratula benghalensis, タマシギ, MERAGI BIASA
– very beautiful bird
– abnormal breeding behavior where the male will taking care after lay egg
– very shy bird
update 202105
– casual lazy birding, driving around. but not a bad morning at all, found this pair of the lovely couple.
– male and female are also beautiful. the one focus is female
It was a lucky and memorable evening! We arrived around 3 PM, and soon had excellent views of Whitehead’s Trogon and a Spiderhunter. Not long after, this beautiful bird perched just 5 feet in front of us, stayed for quite a while, calling and giving us great opportunities for both photos and video.
Charming tiny bird, brightly-colored but difficult to see as it forages quietly in dense undergrowth. Olive-yellow above and dark gray below, with a dark line through the eye and a bright yellowish crown. The very similar Gray-bellied Tesia has a paler belly, a distinct yellowish eyebrow, and a darker greenish crown. Slaty-bellied breeds in foothill and montane forest and winters at lower elevations. Frequents dark damp areas, often near streams or fern beds. Song is a series of high thin whistles followed by a jumble of warbled notes, longer and more complex than Gray-bellied Tesia’s similar song. Gives sharp chirping call notes, as well as loud rattles. [Ebird]
This tiny bird moves swiftly through the bushes, making it incredible that we managed to spot it.
It’s a bird everyone on this trip has been eager to photograph. Yesterday, only Amy and I were lucky enough to capture it, while others could only catch a glimpse without getting any photos. However, luck was on our side today! Two different Tesias came close to us within just 15 minutes, giving everyone the chance they had been hoping for. Tonight, we can all sleep soundly, content with the experience.
This is a fairly common bird in the area, but it moves too quickly to capture good shots. It often hides in dark and damp spots, making it a wonderfully active but elusive subject.
– another bird that we seldom missed since pandemic “covid” (previously seem more shy). This bird just pop up when we trying to locate the partridge. Cute, small and fast
– “side effect” of the CANON RF200800, this bird small, fast and always in lowlight .. end up ISO20000 needed
– as usual very fast moving and tiny bird.but now with the AI camera CANON R7. so much easier with the animal eye detect. almost like point the lens to the bird and press shutter
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)
– 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)
Focal length: mm+1.4x tc ISO: 640
F number: 8.0
Shutter Speed: 1/60
4k 16:9, 59.94p, 200 Mbps MOV/H.265 (HEVC) LPCM, 4:2:0 10bit
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
– very common glass-land, paddy field winter visitor (North)
– mostly brown, long billed, gray leg
update 202411
– It’s great to see them return to the paddy fields, where they are as active as ever in the morning. I came to test out the Canon R1, and with its new Continuous Pre-recording and advanced AF tracking features, I was able to capture the moment they took off and flew toward us. Later, I combined the JPEGs into a single movie file.
– long tie never go paddy field for birding, take a short visit with friend. Very quiet instead but this bird make us spend some time to have good view than follow with good meal
1. Siberian Stonechat, 黑喉石䳭, 黑喉石䳭, Saxicola maurus, ノビタキ, MURAI-SAWAH BIASA
– a common winter visitor(North) normally found grassland, paddy field
update 202012
– this little poor bird with the bill hook up
#
2. Pied Bushchat. 白斑黑石鵖, 白斑黑石䳭, Saxicola caprata, クロノビタキ, MURAI-SAWAH HITAM
– Males are black with a white vent and a white wing patch. Females are dark brown with a reddish-brown rump and underparts. Females can resemble the migratory Siberian Stonechat, but can be separated by the absence of an eyebrow and of any white on the collar or wing. (Ebird)
Small songbird of forest edges, open scrub, and farmland, usually seen in pairs or small flocks. Male is silvery gray overall with black face and white supercilium, throat, belly, and wing patches. Female dull brown overall, with a rufous tail and faded version of the male’s head pattern. Bold but not very active, usually seen perching for long periods on posts and overhead wires. Song is bright and melodious, but often has a somewhat faltering quality, trailing off towards the end. Most common call is a harsh rising “bzeeet!”. [EBird]
During one of the quieter moments while waiting for a Scarlet Finch, a female caught my attention. As it flew around, I decided to enable Continuous Pre-record mode, just in case. Suddenly, it spread its wings, and I seized the perfect moment to press the shutter after see the action, capturing this stunning shot.
