Canon 90D Lens Issues

[mplaforest]

I recently purchased a 90D to replace by 60D. I've been using a Sigma 105mm lens with my 60D for years without issues, however when I attach the 105mm lens to the 90D, the camera thinks the lens is 24mm. When I'm in flash mode, there's an option to select the 105mm option, but I can't override the camera settings of 24mm to 105mm. Seems like a bug, but you can't actuall get Canon to do anything about it. The answer from Canon is "Too bad. Buy a Canon lens". There has to be a way to submit a bug report to Canon to fix this issue. I don't think Canon pays much attention to this forum. Any suggestions?

With your Canon lens?

The reality is, Canon hasn't done a great job with recent camera releases. The first 5DM4 I purchases had to be sent back for repairs because of an issue with the sensor. An issue, BTW, Canon was well aware of and sold them into the market anyway. Do you have one? The R5 release has overheating issues that Canon is struggling to resolve. The latest firmware for the R6 was so bad, Canon pulled it. Canon has quitely outsources some of it critical technology to save money and has discovered this is not working well for them. 

I understand the 3rd party lenses manufacturer has to make sure the lens works with the camera. But I'll be money Canon is aware there's a bug in their 90D firmware that is impacting their own lenses and is hoping people are too bought into the Canon mindset to say or do too much about it. Firmware Release 1.1.2 will probably fix my issue if I decide to keep the camera.

Are you aware of any bug that is affecting Canon lenses or are you spouting jerky comments?

Duh yeah. huh huh! Hence the 1.1.2 firmware release for the 5DM4.

OK.

This has devolved from a productive conversation.

I'm closing this thread.

I just took this after market radio out of my 2005 Ford, and put it into my 2021 Ford and it doesn't work properly! It's Ford's fault!

What a poor (jerky) comment. If the lens works with my other cameras, 5DM4. 1D, and 60D, then the issue it the 90D.

Sorry but its not a poor jerky comment.

Canon is in the photography business for Canon, not Sigma.

When you buy a 3rd party product, it's not the original manufacturers respponsibility to make sure something that they don't make or sell works with something they produced.  or sell.

Its Sigma's responsibility, period.

If you bought a non-Canon branded flash, would you expect Canon to ensure it works with all of their camera's too?  That's not reasonable.  They don't have control of the design, manufacturing or what it might work with.

I suggest you start here:

Firmware download | Support | 105mm F1.4 DG HSM | Art | Lenses | SIGMA Corporation (sigma-global.com...

Ver.1.01
