Hi Sifus, i need some advise about auto focus mode.

Currently i'm doing freelance for wedding actual day job, always use for AF-one shot mode but found some of the photo is oof when i pre-focus and re-composition.

Any idea to solve this? Thanks in advance

Was using Canon 24-70mm F2.8 MK1, will try some test shot to find out the problem again

some reviewer suggested not to put any filter in front of the lens.

object not moving but i just focus and re-compose.

I suspect is the back light problem now

Hey guys, i'm in the market of buying a prime lens (currently eyeing Canon's 50mm F1.8 STM because it's the most affordable one). It's my first upgrade since the purchase of 650D w/ 18-55mm & 55-250mm. I find that my shoots are mostly portraits, so it seems like a reasonable path to get a cheap prime as my first upgrade.

So seeing Canon's upgrade to their famous f1.8 primes, I actually decided to get the STM version. Asked for the pricing with one the famous malaysian shops, and its price is around ~rm500-ish. Consulted one of my friends (wedding videographer/media student) about getting the STM version after trying out his mk.2, but he strongly advised my against buying the STM version saying that the STM doesn't really offer much benefits for the extra price. He said to better use the money for a second-hand f1.4, but if I'm dead set on getting the f1.8 then he would just rather recommend the mk.2 instead.

So, here am I, asking for more opinions, to go with mk.2 or STM? Way-in pls sifu!

p/s I know it's just merely a cheapo lens compared to all the godly lens, it's just an small addition to my camera gear that doesn't cost me a bomb. One of a side-interests of mine hahahahaha.

mk2 using 5 aperture blade, it actually give pentagon shape bokeh

Sharing some shots from my previous wedding reception at a low light outdoor event.

Help needed!

I have this image that I process in LR, but the export image is quite far from what I see in LR. Is there any way that I get the exported image as it appears in LR? Or this is just the nature of JPEG?

In LR

Export image

Thanks

Thanks for the reply. Sorry that I did not specify clearly about my dissatisfaction of the export image. They are the losing of clarity/sharpness and noise of the export image that I got frustrated with, rather than the colour. And the colour profile is already in sRGB all the while.

About the yellow tint, I couldn't really get you. You mean the image appears to yellowish to you?

Okay, I got you now. I changed the colour profile to sRGB and see differences in colour.

I set the quality to 100 with no limit of file size. And thing appears to be even stranger now. With the same image in LR, the image appears to be different when I switch between 'Library' and 'Develop'. When I am in 'Develop' tab, the image is what I want it to be, good clarity and sharpness. But when I switch to 'Library', it appears to be like the export image.

Masda sifu please dont bash me if i did the test wrongly 😊😊😊

Because at the moment there are people with lots of canon glass who seek good 4K video with a 35mm full frame sensor without breaking the bank with the cinema or 1D series.
Many have already migrated to Sony because of this. Some are holding back because of the potential of 5D4.

30 mins limit.
Over heating.
Poor battery life.
Pixel binning.
All 4 of this is very difficult to avoid and dslr/mirror less video shooters have already gotten used to it even in the 1080P era.

30 mins limit is hardly an issue unless you are recording a really long event. In which case over heating will happen first. If however, you take non event videos- this isn't an issue at all.
Battery life can be solved simply by carrying more batteries.

As for pixel binning. Well, better that than a crop sensor.
I don't think they have a choice with pixel binning anyway unless the sensor itself is 4k.

It's frustrating that almost everything has 4K. Even mobile phones. Trust me, I understand it's a lot harder to implement that on a larger sensor... But it's still frustrating.
In a few years time, 4K will be the new 1080P

The sensor technology itself makes it cheaper to produce a 4k sensor for a phone. The demand is way higher too, so they can mass produce it at a very cheap price.

4K itself has a few advantage.
1. Gives you the ability to crop even if your output is 1080P. Even reduce camera shake.
2. Downscaling a 4k video will generally give you more details than a 1080P video. This depends on how (which algorithm) you downscale it, but it can be better than on camera 1080P.
3. Some screens are already in 4K. In a few years time, 4K will be the new 1080P.
As for Rolling shutter.
It's not that bad for some models and its alright for some genre. Global shutter however is quite an old technology even on cmos camera but it'll just be more expensive. That extra cost may not justify the loss in sales.

Of course people have high expectations for the 5D4.  Whatever the specs are now its not going to update for like 4 years.  And video was the focus because that was the area canon been weakest against its competitors.

And many video shooters are Canon users.  Well a lot did jump to Sony.  But Canon users want to see something future proof.  5d3 did that future proof job well as it is still seen as a great camera today.  People worry this might not be the case for 5d4.

And videoguys don't like to be told to buy a pro video camera.  Its expensive.  That's like telling  photographers to go buy an expensive medium format.

Anyways Dslr and mirrorless are seen to do both photos and videos.  There's no turning back.  Even fujifilm has joined in with their xt2 with 4k and f log.

but then people complain M43 sensor too small

Hi Sifus, my canon 6D suddenly has caused some black circle on my photos. Randomly happen. Any idea what happen?

i have attached herewith the sample. I was using Canon 6D with Sigma 35mm. Thanks.

they never bundle the adapter anymore? when i bought my m1 few years ago it came with the adapter.

but all i can say is Canon is definitely getting there, the m5 isnt so far back compared to a6000 and newer m4/3 cameras. good to see that canon is finally being serious about producing a proper mirrorless camera.

they need to make a few more EFM primes and thats it, you already have a good UWA, good superzoom, good telephoto and a walkaround prime.

im not sure too, very curious also. becos i tried many many times. Im using 70D btw. I doubt it was the focus point becos, no matter how i focus, the red dots will never focus on both side (very left & right)
friends of mine told me that it was because my 70D is crop sensor? not full ?
