I am mainly bird photographer and I want to upgrade from Canon 7D to either 5D mark III or mark IV. Prices of these camera here in Muscat is less than US $ 400/=. Please those with experience or knowledge about these cameras can suggest,comment and contribute in this question. Thank you in advance!

Kind Regards,

Do you crop most of the bird images when using the 7D?

If so you will loose too much resolution on the 5D3. At least with the 1D4 you can get F8 focus so for example using the 400 f5.6 on the 7D would be very similar resolution of a 1D4 with 400 f.6 with 1.4 extender. Both would yield a very similar number of pixels on target.

I have both the 7D and the 5D3. I don't consider the 5D3 a replacement. I like to shoot with 2 bodies so I have the 7D setup for longer focal length static birds and the 5D3 setup for birds in flight. The 5D3 has a great focusing system.

Hi Doug,

Thank you very much for a very quick response to my question.I forget to mention which lens I am using with my 7D. EF 500/4L IS mark I is my workhorse,which I am using over 95% of all my shooting+1.4TC.Loosing 1.6 cropped sensor will be very difficult as birds here in Oman are very shy,in rare occassions you can approach very close,during migration when they hungry and thirst.

Wondering the same thing Abdallah except I refuse to pay 3k€ for a 5D, that is stupid pricing. I have looked at the tests, comparisons and feedback and the 5DIII has some smart features but at the end of the day i would never use 90% of them. I want a fast camera with good IQ at higher ISOs, no HDR and a touch sensitive video button.
The 1DIV ticks all the boxes, at 1.3x crop it put more pixels on the subject than the 5DII (at 1.3 dimensions it is about 13MP i think). So all being equal in IQ means your cropping will lower the quality.
PLUS. You can overcome to some extent the lack of 7D crop with a 2x converter on the 1DIV and still AF at f8!! Could be important that and certainly makes the deal for me, and you have enough light to shoot at f8 over there ;) Plus 10fps over 6... it is for me a no brainer. :)

Used 1D4s are dropping to 3k€ at the moment, still a touch cheaper than the ridiculous 5DIII price.

Hi Neil,

This is my guess you are same Neil from Bavaria of old Juzaforum? Nice to here back from old friend.Unfortunately we don't have used market over here and I am not experience enough with auctions,so I leave that to experts.The Mark IV I mentioned are brand new at our local agent at the price of US $ 4500/=.I am thinking also of buying Mark IV and use with Sigma 800/5.6+1.4TC for longer reach,but I am not sure about this combo performance or does anyone here have experience with it?After all wildlife photography is hobby and now is becoming very expensive hobby with prices shoot up day by day,I might settle for what I have.
Thank all for contribution on my question.

Ye it is me :) I hear the Sigma 800 is OK but not sure about TCs on it. The 300-800 is better by all accounts. 4500 US Ds is pretty good, they are 4500€ here, if you can find one ;) So I would buy one in a heart beat. The used ones are not going down too quick, too many people keeping them for the reach of 1.3xcrop over the 1Dx... I will have to wait a bit longer.

Remember, the 500 is one of Canons finest lenses. No Sigma can match it.

I see you lurking on the POTN forum NeilyB ;-) Thats a pretty cool forum, I must post some images there soon... LWP (Lee) is still around, I'm in contact with him. He just hasn't re-registered on here I dont think.

Abdhallah, Ramadam Kareem.
I am from Abu Dhabi. I have your same lens. If you want to try The Eos 1D mark IV and the 5D Mark III just send me an MP. Now I am in Italy for annual leave, but in August I will be back in Abu Dhabi. Maybe we can organize something as a shooting together.

POTN is OK, full of fanboys though, but good for information. ;-) Don't post there though as most comments are just "Nice shot" comments. I stick to smaller communities, as it was here once upon a time.

Abdallah, based on what you mention about your targets I think you would be happier with the 1D IV. With it's 10 fps it will be great for birds in flight. Also, tests seem to show that the low light handling is almost identical to the 5D3 plus you get the f8 focusing with faster focus acquisition.

Good luck.

Dear Doug,

Thank you very much for your feedback,I really appreciate.I was leaning towards Mark IV because of speed and focus at f8,although a bit heavier.
