I recently bought a used Canon 70-200mm F2.8 IS . The lens is in good condition, but it has an issue with auto focus. When you try to focus, you can see the focus ring spinning very fast, but it’s failed to focus , it seems only focus for object over 10mm  or it’s at infinity. After some research, it turn out that the issues was caused by a dirty focus sensor and focus bar.  Below are the 2 videos that will help you to fix that problem. I did it it’s half success – the focus is now working, but i damage a flexRead More →

If you are on free plan, you might realize that you can’t upload any files larger than 100MB. This is the limit that cloudflare applies to Free plan. If you are on Enterprise , you might increase this limit to 500MB. Want over 500MB, you might need to ask cloudflare to make an exception. Cloudflare is great, but 100MB is quite small for video upload. What solution could be? – Upgrade to enterprise (oh no, i can’t afford it) – Disable the proxy – you will not benefit from cloudflare any more – Create a new direct url upload that will not go through cloudflareRead More →

Photograph is my hobby, i like photo detail so i use high resolution camera. This ends with a lot of storage.

My 200GB plan is only $2.99. Why there is no such plan like 500GB or 1TB. I started to look for someRead More →
