A question: what's the point of AF-S? Seems to me like AF-C gives you the same functionality while also being able to compensate for movement of yourself or the subject if necessary. In short, AF-C does everything AF-S does ... and more.
hello all,
I recently decided to upgrade my telezoomlens to a sigma 150-600 sports. Problem is it seems like the lens has trouble autofocussing on distant subjects at 600mm. At 400 or 500mm it does autofocus on the same subjects. Manual focus works fine at all distances. I went to the store and they tested the lens saying it works as intended. The person helping me indicated it is likely my body (7dm2) is not a good fit for this lens (too old/different generation). Something about the 7dm2 needing higher contrast for the af to work (translated explanation so might not be entirely accurate). This would also be why on my old lens (the old Tamron 150-600, not g2) the af works better.
They recommended a more recent body, like an Eosr or r6, but I'm curious what your thoughts are on this, and also, if you would change the body what would you suggest? My use case is wildlife (birds mostly) and budget could go to about €3000 max if it entailed a big improvement in image quality, low light performance etc. If there's something good for less I would ofc love to hear it. I do like all the options my 7dm2 gives.
Thank you in advance!
I mainly use my A7S3 for video, but I also occasionally use it as a stills camera. At a recent family gathering, I decide to take a nice group photo using the timer option, with my Sigma 24-70 f/2.8 ART. Autofocus was on, aperture priority mode.
I took a few photos, and upon careful inspection (after everyone went back to doing there own thing) I realised that NONE of my 3 photos was in focus. I tested this a few times back at home, and my Sigma simply won't auto-focus correctly when in timer mode.
When in every other mode, such as normal shutter, or video AF-C, it focuses fine. But in timer mode, it just NEVER focuses right, even when you do tap to AF, etc.
Is my unit defective, or is my Sigma lens just bad?
Just started playing around with my XT-30 and I'm having some difficulties with the autofocus. It seems to be a little slow, and in most cases missing completely.
Do I have the wrong settings perhaps? I have heard people complain about the speed of the autofocus previously.
EDIT: I'm using an XF35mm F1.4R lens. I switch between S and C autofocus modes. I've been experimenting with face detect and autofocus points which have helped slightly, but am overall finding it rather slow. It doesn't focus quickly enough to catch the moment.
The title sums it up, but here some more info:
I've been using my D7500 for a year or so for wildlife photography, mostly birds. I pair the Nikon with a Tamron 150-600 5.6-6.3 and have been mostly satisfied, but the combination really falls down in certain situations.
Firstly, in spite of the long lens (and 1.4 crop sensor) it's not always possible to get a good frame-filling shot of my subject (often smaller birds). Therefore I'm thinking that one remedy to this would be a higher pixel count, allowing me to crop in tighter. Perhaps a full-frame sensor would be a good option? - I'm fairly new to photography so please correct me if these assumptions are wrong.
Secondly, the autofocus on the 7500 is in my experience good, but not great, and I really notice it struggling, 'hunting' for the subject. This is naturally worse in low-light conditions.
Finally, I'd like better low light capabilities, i.e. less graininess at high ISO. This is particularly tricky because I live in the UK and our weather is quite often cloudy and overcast(!) In such conditions I find that I can't push the 7500 much beyond 4000 ISO. I believe that a full-frame sensor could give me an overall brighter starting point, if that makes sense?
Any ideas are very welcome, and please ket me know if I can offer any more information!
Edit: I should say that budgetwise, I'm looking to trade in my D7500 body and am happy paying a few hundred also
I’ve adored shooting with my X100F over the last two years, but I want something a little more versatile for travel. I plan on selling it and purchasing a X-T3 or an X-T30 with the 18-55 lens to start.
I’ve read in a few places that the auto focus on the X-T30 is worse at tracking and may be a little slower overall. Would anyone who has shot with both consider this a dealbreaker? Does it factor in for video? My kids are constantly moving, as they’re at that age, so I’d get the X-T3 if it’s a significant difference. However, I’m also drawn to the smaller size of the X-T30.
Thank you in advance.

Is that the end of Hoonigan AF ?
Hi Fujifam,
Does anyone have experience comparing Fujifilm's 16mm 1.4 and 18mm 1.4 lenses on an X-T4? I'm looking for it all - the good, the bad, and the ugly - but ask the question out of hopes for better autofocus reliability.
I've been using the 16mm 1.4 on my X-T2 for years, but since getting an X-T4 it has been focusing inaccurately on the newer body. Don't get me wrong - it focuses fast, but focusing on the same spot repeatedly yields slightly different focus each time (varying by up to a couple of meters). Shooting wide open at 1.4, this results in more out of focus shots than I'm used to - particularly at distances beyond 1.5 meters - and so I now only manual focus with this lens/body combination.
In terms of it potentially being user error: I use back button focus with the "instant AF" setting mostly, but have tried every autofocus setup (including doing a factory reset on the camera). I also recently sent my X-T4 in to Fujifilm, and they cleaned it but otherwise told me it is up to spec.
I'm seeing similar focus (mis)behaviour with my 23mm 1.4 (v1) lens, and am wondering if perhaps the problem is due to the nature of the new camera with the old focusing mechanisms in these lenses. They continue to focus reliably on my X-T2, but inconsistently on my X-T4. Other lenses seem to work fine on the X-T4 (56mm 1.2, 18-55mm, and 55-200mm).
This all leads me to wonder if perhaps the new 18mm 1.4 would work better with the latest Fujifilm focus mechanisms. I need to be able to rely on my photography tools again, and I hope to find a way to do so within the Fujifilm ecosystem before looking elsewhere.
Does anyone else have any experiences comparing these two lenses? Whether it's with regards to what I wrote or other aspects, I would appreciate your shared understanding. I do plan to go to a camera store to try and experiment myself, but it will be a couple of weeks before I'm able.
So I have a Nikon Z50 and quite a few vintage manual lenses. I've found out there are autofocus adapters that work with manual lenses. Does anyone have any experience with them? It seems there are few tests that actually compare which is better.
inb4: Yes I could get native z lenses instead of using old soviet ones. Yes, I know how to shoot manual lenses and can get the focus fast (focus peeking is great). The only reason why I need an autofocus adapter is because my partner can't work the manual lenses and I'd love to get some nice photos of myself.
Well, as the title says, I've been wanting to try film photography ever since but haven't had much time before as I do now. My choices are either Pentax me 50mm and Yashica Autofocus. I know that this is a pentax sub and the suggestions might be biased but the thing is I haven't seen any decent reviews regarding Yashica. so yeah!
everyone says it's bad
but i feel like it's just a bad reputation got blown out of proportion especially in comparison to phase detection autofocus systems
when i vlog with gh5, the autofocus looks just as good as A7RII that i used to own
yes there are certain situations that the autofocus suffer
but in general i think it's way better than people give it credit for
it feels like a lot of people don't even try autofocus with it because they hear it's bad
Anyone else experiencing autofocus hunting?
Just started on my p6pro.
Pretty annoying they removed the AF lock option. At this point my pixel 3xl is better for video than the p6pro.
For sale today is my Nikon F3 (Body Only), and a Nikkor 50mm 1.8 G lens. Note, the Series E lens attached to the F3 is not for sale.
The F3 is in great condition, with the standard eye level finder. All shutter speeds are accurate, the meter works, and this camera has been film tested. The only notable condition wear is the eyepiece shutter, which closes the viewfinder for self-timer shots. The plastic switch has fallen off. The metal mechanism underneath still works. If this is an issue, I can sell a near-mint viewfinder separately.
Asking $240 OBO for the F3 SOLD
The 50mm G Lens is in like-new condition. Includes box, papers, and pouch. I took great care of this lens and it always had a filter on. This works with all Nikon autofocus digital cameras and the newest film bodies (F5 onwards). Beautiful images and one of my favorite lenses. Sad to see it go, but I don’t shoot Nikon digital cameras anymore.
Asking $150 OBO for the G Lens SOLD

Looking into getting the R6 but I have tons of EF mount L series glass. I'll be shooting exclusively video with it and am wondering how the video autofocus works with the adapter ring. Autofocus is a big reason I'm wanting to upgrade, but don't want to replace all of my lenses unless the video AF just doesn't work with the adapter ring for some reason. Thanks!
I have taken delivery of my S5 in early December 2021, and have been using adapters with my existing lenses in manual mode (Nikon AF-S, Minolta MD) before starting to commit to L Mount lenses.
Previously I was using the Fujifilm X mount, and their 23mm and 27mm APS-C lenses (corresponding to 35 and 40mm in full frame) worked out quite well for what I have been doing:
I mostly do family portraits and architectural photography, so the 35mm in full frame works out for me. I have also done product photography, and a 50mm lends itself nicer, although I do prefer to manually focus for this type of subject, so the second L mount lens on my list might be an autofocus 50mm.
I would also like to start vlogging in 2022, but continuous autofocus is not a deal breaker since I will be using an external monitor, and if needed I can focus in manual mode.
In terms of form factor and price, I have ruled out the Sigma 35 mm F1.2 DG DN Art and the Sigma 40 F1.4 DG HSM for their size and price.
After perusing written reviews and YouTube, my three contenders are:
If I understood correctly, the Sigma F2 is the most compact but the noisiest, and it would be the most suitable for photography. Coming from the Fujifilm X system I can appreciate the analogue aperture control.
The Lumix F1.8 is the most plasticky but it would be the most suitable for video as it is silent and it handles continuous autofocus slightly better than the Sigma F1.4 and has less focus breathing than the Sigma F2. Besides the focus ring, which can be used manually, everything else is set electronically.
The Sigma F1.4 is the bulkiest, but seems to offer a slightly better optical quality than the two others, although it slightly underperforms the Lumix F1.8 in terms of continuous autofocus but it offers the most analogue switches: AF/MF, smooth aperture or clicks.
I am inclined to go for the Sigma F1.4 because I would probably enjoy the analogue controls, but I am afraid that I would get tired of the weight and 330ml soda can size.
Does any one have first hand experience with either of these lenses? Is these a detail that I am overlooking?
Hanks in advance.
Hey there.
I want to start a video series where I write something on a whiteboard, gesticulate and show electronic components. So I need a camera with good autofocus and an appropriate lens.
In my mind comes a DSLR camera also because I want to create better pictures in my holidays than with my phone.
As a beginner I don't want to spend a huge amount of money (< 500 $), so some old stuff (< 5 years) from ebay. Is that realistic?
Do you have some suggestions? Thank you.
Hello,
My primary camera's autofocus sometimes doesn't work at all, and sometimes it works just fine. The other day it was working, but it seems that after the update, it stopped working again. If it's not working, it's focused on objects very close to the camera, if I tap the screen to focus somewhere, it doesn't do anything.
Is this a known problem, or is my phone's hardware broken?
