60D owner for 10 years deciding whether to buy R6 mark 2 or R7?

[kodiakak]

I do a lot of wildlife photography Bears Birds and I'm in the field. I tried the R8 a good camera but battery life small buffer inadequate evf what's the deal breaker. I have a lot of money tied up in Canon lenses so I'm sticking with Canon for me the choice was either R6 Mark II or R7. Only hesitation is the full frame crop factor on my 400 mm lens. can I compensate with an extender? Zoom in photoshop?

What lenses do you already have and what is your budget for a camera or a kit (camera + lens). Please provide the full name of the lenses you already own. Are they Canon brand lenses or 3rd Party lenses.

Hi Demetrius

All Canon lens.  100-400mm EF USM , 18-200mm EFS,10-18 EFS, 40mm EF STM. Budget not unlimited but concider anything

[deebatman316]

Can you provide full model names of all the lenses. The EF 100-400mm has had 2 revisions. We need a budget. I also think you mean EF-S 18-200mm. Older lenses DO NOT support all features on the EOS R series. EF or EF-S STM zoom lenses support DPAF (Dual Pixel AF). Ring Type USM lenses released in 2009 or later and Nano USM lenses support most if not all features on the EOS R series. Micro Motor, Micro Motor USM, Ring Type USM lenses released prior to 2009, EF or EF-S prime (fixed focal length) lenses and AFD lenses don't support all features on the EOS R series. They also don't support DPAF (Dual Pixel AF) either. These lens' AF motors and aperture motors are too slow to keep up with mirrorless cameras. Note EF-S lenses causes the camera to apply a 1.6x crop. You also lose image sensor capacity since the lens projects a smaller image circle. For instance the R5 has 45 megapixels in Full Frame mode. But in 1.6x crop mode it's only 17.6 megapixels.

Thank you. Very usefull info. 40mm, 10-18mm and 100-400mm usm Rev 2 purchased from cannon 2019. The 18-200mm efs 2010. 2k budget for new lens. Dan

The EF-S 18-200mm is NOT fully compatible with the EOS R series. It uses a very old and slow AF motor called "Micro Motor". This type of AF motor was released back in 1993 and has been retired years ago. It CAN NOT keep up on high FPS mirrorless cameras.

Agreed.  I would question the value in depending the choice of FF vs crop on the fact one has an old lens that cannot be ported across to the R platform at all. Given a budget of $2k, that offers the opportunity for some great glass from Canon that is native RF:  I have already mentioned the RF 100-50 and 200-800, but for a lower range the excellent RF 24-240 is a brilliant optic with a very wide focal range especially since the 18-200 under discussion would have an Equivalent FoV of 29-320mm which is not that different.  Alternatively, the RF 24-105 (3 versions) and RF100-400 would give a massive focal range for FF in two lenses.

I was going to ask the OP what they mainly shoot. I was going to say sell off the EF-S 18-200mm F/3.5-5.6 IS Micro Motor lens and EF-S 10-18mm F/4.5-5.6 IS STM lens if moving to Full Frame. The RF 24-240mm F/4-6.3 IS USM would be a great replacement to the EF-S 18-200mm F/3.5-5.6 IS Micro Motor lens. The RF 15-30mm F/4.5-6.3 IS STM would be a great replacement to the EF-S 10-18mm F/4.5-5.6 IS STM. The OP said a max of 2K for a lens. That fits in under budget. Since the EF 100-400mm F/4-5.6 IS II USM & EF 40mm F/2.8 STM are newer lenses they can be adapted very well. Those 2 lenses will also allow all features to be used on the EOS R series.

This was the first sentence of their first post:
"I do a lot of wildlife photography Bears Birds and I'm in the field."   Which is pretty much what I shoot.
To me, that suggest long FL lenses that have great image stabilization.  For the RF mount that would be:
100--400  at minimum  quite low for bears
100-500  awesome lens, not cheap
200-800  new kid on the block, not a L, but well-built and fantastic FL. 
I tried a sample unit and am really impressed. That would work well with the FF R6II

[deebatman316]

The OP edited their opening post when I originally posted my comment earlier. So would selling off the EF-S 10-18mm, EF-S 18-200mm & EF 40mm lenses be a better choice. Since most wildlife is shot at 300mm or longer. Investing in newer RF Mount lenses instead such as the new RF 200-800mm USM. Then adapting the EF 100-400mm or selling it and replacing it for the RF Mount equivalent.
