What camera and lens was used? Model names?

The 3D tracking of Nikon is quote good. But not sure how it is on the D5500. Best would be to experiment and see what best works. But most important – you need to understand what all AF points are available on the camera and what each does.

That should not happen depending on the dimension of the image and the resolution you share. Can you please share your workflow.

Dear Renukumar, You can refer the A9 II or the A9 III course depending on which menu options match as all sony camera menu options are the same. These camera related courses helps you understand the camera functions and settings.
For learning photography using these cameras, you need to refer to the other courses.

Ok, going through your reply, looks like there is an issue with the lens and you need to take it to service centre. What you have explained – that’s not common and is definitely not how a Sigma 150-600 behaves.
As an alternative – I would recommend you to try and test with a different Sigma 150-600 (if you can rent it) and compare the results.

There is nothing called as the best setting. You need to invest your time in learning the concepts. If you are my Online Photography Course student, please go through the course as per the learning path:

Go for the new one. It’s good.

Dear Mohan Khullar,

Can you please explain what exactly is the AF issue you are facing? Also need answers to below:
– What is the AF point you are using on Canon 90D.
– Can you please share images where you are facing issues.
– Are you using One Shot mode or AI Servo?

AF hunting happens due to multiple reasons including:
– low lighting
– Distractions in the scene
– Subject not properly visible to lens
– If you are using any kind of filters to the lens

And to be honest, the Sigma 150-600mm is not a fast lens to get you good AF.

Rgds,
Sudhir

We have found out that this issue happens only on Android phones where the photos are stored on google photos and not on local phone. It will take time to fix this issue.

Alternatively you will have to upload images from a comp or any device where photos are stored locally.

[Sudhir Shivaram]

Please mention your city and also what kind of prints and for what purpose.

You have mentioned supporting lens gear but have not mentioned what it is. Camera is ok, but depends on lens. Don’t upgrade or change just for the sake of it.

Start shooting with what you have and once you find the issues or drawbacks of existing equipment, only then think of change or upgrade.

For any of the Nikon mirrorless, you can refer the Z9 course.

Good question — and since you already have a Nikon D500 and are thinking of Nikon Z50 II, it’s useful to compare realistically what you gain and what trade‑offs you accept when switching. Below is a balanced, expert‑level take based on real-world performance and how it aligns with wildlife / bird photography (which you focus on).

✅ Where Nikon Z50 II Does Well (and Makes Sense)

• The Z50 II uses the same APS‑C (DX) sensor size as the D500 — so you keep the 1.5× “crop reach” benefit that is often useful for wildlife/tele lens work.

• The autofocus system has been modernized: Z50 II offers hybrid on‑sensor AF with subject detection including animal/bird eye‑AF, which is a significant plus for bird and wildlife photography.

• Burst shooting: mechanical shutter continuous shooting at 11 fps — nearly on par with the D500 (10 fps) for action/flight shots.

• Mirrorless benefits: lighter body (makes handheld walking/traveling easier), electronic viewfinder and live‑view benefits, silent shooting (good for shy wildlife), often more convenient for travel due to compactness.

• Modern processing: Faster image processor, improved usability, newer interface and ergonomics, which may help in today’s workflows (especially if you also shoot video or hybrid content)

So if you value lighter gear, portability, modern AF with bird/animal detection, and a mirrorless workflow, the Z50 II can be a good companion — especially for field travel, casual wildlife, birds, perhaps travel + wildlife mix.

⚠️ But — Where Z50 II is Not a Full Substitute for the D500 (Especially for Pro‑Level Wildlife Work)

• The legendary build, ergonomics, battery endurance, and AF reliability of the D500 remain hard to beat — many experienced wildlife shooters still consider D500 one of the best APS‑C DSLRs ever made.

• While Z50 II is strong, some long‑time users say that for demanding wildlife (fast birds, erratic movement), D500’s DSLR AF and handling still give an edge.

• As of now, lens ecosystem for Z mount (DX/APS‑C + full‑frame Z lenses) may be catching up, but for heavy telephoto wildlife needs, you need good Z lenses — and that often comes at cost or weight penalty.

• Lack of in-body image stabilization (IBIS) — for handheld telephoto work in low light, this remains a limitation compared to setups where lens or body stabilized systems exist.

🎯 My Expert Recommendation (Given Your Background & Use Case)

Since you already have D500 and are comfortable with it:

• If you want a “lighter, travel‑friendly second body” — Z50 II is a good add-on (not replacement). It offers modern AF, portability, and mirrorless ergonomics that complement your heavier telephoto setup.

• If your core work remains serious wildlife, fast action birds, consistently high performance, I would continue with D500 + good tele lens — because D500 still holds up extremely well, especially in challenging conditions.

• Use Z50 II when you need flexibility: travel safaris, daylight shoots, or as a backup body — but don’t expect it to fully “replace” D500 for critical wildlife shooting situations.
