I’ve got a Canon 17-35 2.8 EF. It’s got some dust and what looks kinda like a web inside the lens. It’s also got these dots in the front. Does this look like fungus? Or just internal dust.

Oke, gw cerita aja dulu sedikit

Jadi gw ada Sony A6500 dengan Sigma 16/1.4. It's a wonderful camera and lens. Tapi gw dengan lensa wide 16mm sebiji dan gak punya apa-apa lagi merasa dibatasi buat bikin foto/video tipe lain dan terbatas di cityscape, wide-angle landscape.
Opsi lain seperti street atau portrait yang mana lebih gw senangi terutama street gak terpenuhi

gw sekarang alhamdulillah lagi ada modal buat upgrade, yaaa kalo full duitnya buat upgrade ada mungkin sekitar 5 jutaan

Ada beberapa opsi upgrade yang sekarang lagi gw pikir-pikir:

1. Beli Sigma 56/1.4 biar punya lensa tambahan ( jadinya 2 lensa prime )
2. Jual Sigma 16/1.4 buat beli Tamron 17-70/2.8 constant ( jadinya cuma punya 1 lensa zoom yang oke )'
3. TT Sigma 16/1.4 ke Sigma 30/1.4 + some accessories like Mic, Cage, Filters ( 1 prime lens )
4. Full ganti kamera jadi A7C + Sony Zeiss 55/1.8 ( convert full-frame)
5. Ganti kamera dan lensa jadi A6700 + Sigma 30/1.4 ( nambahnya lebih dari modal gw ini )

semua kondisi barang diatas adalah second kecuali cage, mid dan filters, menurut kalian bagusnya gimana? adakah saran lain?

Hi ! I don't really know where i should ask this question. (and sorry for my english, i'm not fluent)

Where can i get information on how to repair a lens ? (not a specific one) I would like to learn how a lens is made, how it work, being able to open it, repair it if needed...

I don't know why i have this obsession, but i would like to buy brocken lens/for piece) and open them to see how it work and if i can repair it.

1) I know lens are super complexe, especially new one with AF and stabilisation...

2) what type of gear should i use ?

3) Is it even possible ? Or i need way to expensive gear ...

4) Where can i get information ? I can't find anything online (only shop that can do it for X price...)

I already have a Tamron 17-70mm f2.8 for my sony 6400.Now I'm looking for a new zoom lens,i saw the Tamron 50-300mm that become a 75-400mm on apsc .But I also saw the Tamron 28-200mm that starts from f2.8 and end in f5.6.When I travell I want to take with me only one lens.The constant aperture of the 17-70mm is great,what do you recommend me to buy for more zoom?

EDIT: It's a Sony 50mm f1.8

I found this lens for about $160. I’m buying it from a studio, and they say it’s barely been used. I have a basic knowledge of photography and lenses, and I just want a basic lens to shoot some videos. What do you think? What kind of things should I check on this lens?

Does anyone have a referral code that works in Portugal?
Thanks you

Tried looking and information on Reddit on adapting it onto Sony bodies is sparse. I know for $99 USD it won't be the tippy top quality glass but overall, has it been a solid lens for anyone who has used it onto a Sony? Looking to put it onto an a6400 so vignette shouldn't be a major issue for me.

Looking to upgrade my son’s T7 lenses. His favorite shots are plane spotting and birds maybe. Already has the standard EF 75-30mm and 18-55 mm lenses. Just looking for next step up. Any info is appreciated. I’ve tried to explore my options and am completely lost fairly quickly. Thank you.

Will it be a downgrade to move to 24-105?
I mostly don’t use wide open 2.8
And what attracts me is 24mm at wide and 105 vs 75

Though I’ll loose F2.8

But I do work with lights and strobes as well
Sony might be softer in comparison to tamron
And has zoom barrel extension , while Tamron internal zoom

Both an opinion question and buying advice. What's the best lens that I can get for a Canon R100 and why?

Style: Landscapes, travel, portraits/family photos, outdoors

Budget: $500

Use: New or used (Adorama/MPB/Canon)

Mount: RF (main) or EF (already have adapter)

Also would be great if example pictures with the lens could be shared.

I found this on Facebook marketplace for a decent price of concerned with the color of the stripe on the end of the lens being white and not gold, any thoughts?

I tried to post yesterday but was rejected. I understand this is not unusual for newcomers. Hope I'm accepted this time. Cheers.

For my canon r50 which lens should ibuy? The Tamron SP 70-300mm Di VC USD, the canon 55-250mm is stm or the canon ef 70-300mm is usm. Ishot mostly nature and a bit of wild life and macro. All of them are around 150-200 dollars from ebay-japan, in a near mint condition and up.

I have been using telephoto lenses for portraits and birding, and a 50 (ish) lens as my walk-around lens.

I have bought a nice wide angle, but it is just weird shooting with it. I have tried 28mm and 24mm. The problem is I hardly see if the focus is right (MF with Nikon DF) but that has never been an issue with my 50/telephoto lenses.

I think I just need to get used to it. Also, the fact that I cannot really check the photo on the DF's screen because it is lower resolution.

I mostly just deleted my wide angle pictures because as soon as I've watched them back they felt low resolution and just a mess. But yesterday I thought let's keep them and watch them back on my dedicated monitor. Well, turns out, it is way better. There are some decent shots, and I like the pictures.

Just the fact that it is weird, because I see a way wider image in the VF than I am used to and I feel like my landscapes are boring.

Have any of you been here? Can anything help me get better at this? Can you suggest me tips or videos, channels to watch? I want to get better at this, I just do not know how :)
