After half a year I've decided to publish something on Steemit for a simple reason - why typing in Word and consequently lose the file somewhere in wastelands of the hard drive.

Nikon, I don't like them, I don't care, waiting for Z6/Z7 to become second hand

Canon

5D, Mark I

Thank's to Sony a7 and Brother 6D, this classic becomes unsellable.

At any moment, you can find them for 250-300 EUR, but if you want to invest some patience, it can be yours for as little as 200 EUR.

5D, Mark II

For some strange reason, there is a plentiful of cameras in semi-operable conditions.

Being a professional's workhorse is not easy, and the majority of them are half dead.
6D is better for any reasonable person, making 5D Mark II not worth more than 350 EUR.

However, their owners are in love with their faithfull companions and often ask unreasonable prices.

5D Mark III

The beast with 2 card slots (read: PRO...)

Prices start from 600 EUR without negotiations.
Is it worth for a pro who can't afford losing images - YES!

6D

Canon for normal enthusiasts. The sensor is good enough, while the body is survivably heavy.
The biggest drawback is poor AF system. On the other hand, it has the best central spot ever seen...

400 at any moment, 350 EUR if you are lucky

Sony

a7

Little bastards that flooded the market like a swarm of locusts.

400 at any moment and 350 with some luck.

a7 S/R

Who knows... The market for them is so small that it's a tough question.

a7 II

The main reason why a7 should be avoided as a plague and re-sell asap.

With IBISS, it's the whole class better + you get a human-size grip.

You can find them for 500. Best buy for vintage lens lovers.

Conclusion

• 5D, buy for 200 EUR or less, pray to god selling them for 250 if someone is crazy enough

• 5D Mark II, buy them for 300 or less, try to compete with 6D in 350-400 EUR range

• 5D Mark III, try to find them for 550 and start shooting like there is no tomorrow

• 6D, aim to price of 350, and try to find an example used by a regular person

• a7, stupid thing to buy, unless it's 350 or less. Flip them the very next day because...

• a7 II is starting from 500 EUR making it the best buy if you don't find Sony's colors disgusting
