The Autofocus system same like R3, R7 which allow more AI AF capability

few special features for the moment only available on R3, R7 and this R6II which I feel it is very useful for wildlife Photography

CANON R7 a very good Shortcut button Setup for Wildlife Photography

CANON R7 : Raw Burst Why & How

###

Here is first outing, even very quiet morning, but manage to have some thought of the Camera with real field experience.

Later I will also share more like ISO testing, AF (think it is more a like a focus little monster like R3 but what I love to see is low light AI animal detection)

the focus is amazing fast and accurate as expected. as long as the Zone box tough on the bird. Eye will be detect and lock focus.

for such a black bird with red eye and some backlight, the eye detect work seemless.

3 days with CANON R7 + RF600mm F4 (ii) – AF Tracking

continued from previous CANON R7 sharing

3 days with CANON R7 + RF600mm F4 – IS, Battery life, AF, ISO samples

This test mainly concentrate on AF tracking (on subject – bird). Even I dont have enough chance to shoot many AF tracking and this is not my normal testing AF condition. Where I normally test AF, AF tracking with “un-plan” flying subject. Where I do not have any idea where the bird flying from-to and just use camera reaction to lock focus and track to capture the pictures.

This is a “pre-known” the bird will flying toward us or left/right.

i. lock focus the Bird eye 

ii. AI Servo

iii. tracking enable

From the series pictures show, the bird is focus in every frame and also can see the tree is out of focus slowly at last few frame where the bird flying away from the tree. This show the bird tracking is working perfectly

 

DxO PureRaw 2 Noise reduction performance … CANON R5 & SONY A1

few months ago my friend introduce to me “DxO PureRaw 2” for very good noise reduction. I am bit busy last few months and finally I have time download to check out ISO performance of Fujifilm XH2-S , CANON R7 which both APS-C sensor which most the users concern on ISO performance. But we know when smaller sensor normally has more noise with bigger sensor camera (with same megapixel). Too bad both camera raw files are not supported by the DxO PureRaw 2. But I decide to make a simple test with CANON R5 & A1

几个月前,朋友介绍了这款新的软件。大概是降噪非常好,比我之前介绍的Topaz Denoise 好。

我一直较忙,这几天终于有时间坐下清理照片。处理一些事情。还有最近试了2架新的半幅的相机(富士 XH2-S & 佳能 R7) ,大家(包括我)都有点担心点问题。因为我们这的摄影环境都较暗。我们也希望有较长的焦距,半幅的相机都是我们想用可是主要担心点问题。

可是,这个软件 DxO PureRaw 2 尽然还不支持这两架相机,可是尽然已下载。我也试试在高像素相机之一的佳能R5 &索尼 A1 (迟一点会放上)

Simple test with CANON R5 & SONY A1

I only test 2 ISO – ISO2000 because this is my comfortable accept ISO for R5 and ISO6400 is my highest auto ISO set for R5 & ISO4000 for A1 .

– Click the picture to see original full size picture.

– the DxO PureRaw really process the raw file into a DNG file with very good noise-details balance output.

– please support original software

my recent posts

3 days with CANON R7 + RF600mm F4 – Battery life, AF, ISO samples

Field experience with Fujifilm X-H2S + Fujinon XF150-600mm f/5.6-8

 

3 days with CANON R7 + RF600mm F4 – IS, Battery life, AF, ISO samples

I am glad been given a chance to use the new CANON mirrorless camera R7 with RF600mm F4 for 3 days.

When I have the camera with such period, I know I can’t try everything I want to try but for another successor after R5/6/3 think most of the people will have same believe and doubt as me

1. AF should be as good as the R5/6/3

2. such high megapixel, how’s the ISO performance

3. Image Stabilizer – as think this is one good camera for bird watchers who normally shoot handheld

– should have more time to try with RF100-500, RF100-400, EF 100-400, EF400 F5.6 etc

4. video quality, overheat concern

5. buffer as only SD card supported

6. Video AF

7. Battery life

###

For me, I am concentrate on few above which I “worry” about

AF

ISO performance

Image Stabilizer (which affect the Image quality – ISO)

Battery life

Video Quality (after recent so many good video hybrid camera)

###

Here is my 3days real field experience for above mentioned concerns

update 20220618

4. Image Stabilizer

– this is one most important criteria for most of Bird Photographer as in many cases we do require to handheld to shoot with smaller lens and most of this situations when we inside forest which also having lowlight.

– if the IS efficiency is high, mean we can get higher success rate picture with lower shutter speed .

– I am using R7 with CANON RF 100-500mm which also 160-800mm (35mm equivalent) and I tested all with 500mm (800mm 35mm equivalent). without any tripod, monopod just handheld with various shutter speed and 10-50 shots (average)

– 我在测试佳能的新R7与RF100-500mm。这个测试是为了试机身+镜头防抖有多好。因为这可是我们选摄鸟器材的蛮重要的一环,因为在马来西亚很大部分时间我们都在林里拍鸟。都是不容易带脚架与蛮暗。手持摄影需要好的防抖功能让我们在较慢的速度下拍到我们要拍的鸟。

 

update 202206

– due to work nature, I am capturing still and video handheld 90%. So IS always one of my very important criteria to choose my “working birding equipment”

– another quick test how’s the IS for video with CANON R7

– 工作关系,我几乎都是手持拍摄(照片,视频)。相机+镜头防抖功能变成我主要选择我的摄鸟(工作)的其中一个主要的功能。

– 当我拿到R7,这是我要测试的其中一项。手持视频

 

case 1 : 1/15s

– shooting 1/15s total 59 shots and 20/59 is focus which giving 33% I would say it is very good

CANON R7
CANON RF100-500mm
500mm (800mm 35mm equivalent)
ISO400, F7.1, 1/15s

 

 

1. Battery Life

– one of the amazing battery life mirrorless camera so far

– 3 days in the row, shooting from 7am – 2-3pm without power off the camera

~1200 pictures

~10-30 video (4k)

ALL 3 days still have >50% battery remain

 

2. AF

– without any doubt or different, the AF capability to find subject eye (bird eye) simply awesome. AS GOOD AS R3, R5 and R6 for bird eye detect, I dont have enough time for flying tracking (only very quick tried)

– the best part is this camera use R3 AF method e.g. when use ZONE or single point in R5/6 the eye detect cannot be use. So most of us use method of either

a. let’s the camera find the bird eye in full screen – some of us just don’t trust the camera. So dont border of using this method but for me this is very fast and 90% trusted method

b. use one button for single point focus than AD-ON (any other button) eye detect

– this is a much slower way of AF which require single point to point to the bird than need press a button to have eye detect than follow by shutter button for picture capture !!!!!!! not only slow with so many button pressing more camera shake created

– now, we can use single button set to single point, zone, full screen as long as the point, zone or camera found the bird. The “eye” will be focus and track

###

3. ISO performance

with such high megapxiel 32.5 MP, think everyone most worry is the ISO management.

here are some pictures sharing

series of picture (full size) 800-10000 (sorry for accidentally deleted ISO400 pictures and due to environment here we seldom use anything lower than ISO800

I also make a simple Topaz Denoise (default auto) to have a look with minimum post processing result.

###

My personal view, for such a high megapixel APS-C camera as expected it provided so much details and with noise when ISO increase.

Based on the simple noise reduction (one click) the picture image quality  seem well balance with details+noise at ~ISO3200. Extra post processing should able to produce more clean picture.

###

 

Let;s wait for coming sharing

Birding Photography with Fujifilm X-T4 | AF Test | liewwk Nature

Sharing some of my AF testing on Fujifilm X-T4 with various lens combination

Test 1

Fujifilm X-T4

Canon EF500mm F4 IS2

Fringer EF-FX II

Setting

ISO 1250, 1/3800, F5.6 AF-C, Zone AF (2nd largest area)

#

the bird (tern) has enough contrast again this kind of background.

Overall, it lock focus on the bird fast and track well too as long as we able to follow the flying path and no big change of background condition

*** the AF Range limiter will help faster and better tracking

*** smaller AF zone also help faster and better tracking

CANON EOS R6 : Video AF test | liewwk Nature

Both the still and video AF performance are different in almost all the camera. Here is one of the video AF with

– CANON EOS R6, CANON EF 500mm F4 IS2, CANON 1.4x, CANON EF=EOS-R adapter

– Tripod

– AF method  : the only method using Full sensor area in R6

Face+Tracking

– Subject to detect : Animals ; Eye detection : On

 

 

The AF seem slower lock focus to the object compare to still AF. which normally require 1-4 seconds to lock the object. After locked focus, the tracking seem work well but still 20-40% chance lost focus especially bird eye/head not detectable. But it will get the object refocus very fast as long as we able to follow the bird movement.
