make it 10 bit 60p $2k, no auto focus to compete with pan s5. if its 8 bit only, i'll actually laugh.

Rumored specs

• Slight bigger and more comfortable body than A7III
• 3.68M dot EVF
• 1.44M dot LCD
• Newly developed 30 MP sensor
• 4K 60p with no overheating
• Dual SD and CFexpress Type A card slots
• New menu system from A7S3
• 5-axis in-body stabilization with Steady shot active mode
• Price 2.499$

Another try

• A7 IV will have a new sensor with faster readout and will not recycle the 24 MP one. My source told me it will be in the 30-32 MP region
• The EVF will have 3,69 Mdots and not 5,76 Mdots
• LCD will also be on the cheap side but the image quality and AF will be top notch
• The video will certainly be 4K 60p and will feature the new menus.
• The price will be in the 2499$ region

Announcement no sooner than September 2021.

Sony now experience shortages of lot of components even for existing cameras.

New rumors

• Will launch in October, if chip supply permits this
• Has newly developed 33MP sensor
• 5.5 stops IBIS efficiency

A7IV rumored specs:

• launch in October, if chip supply permits this
• Has newly developed 33MP sensor
• 4k30 video is oversampled from 7K
• 5.5 stops efficient IBIS (+ AS)

VK you think they will give us close to 13 actual stops ? And is this the next thing that will improve dramatically with camera manufactures ? We went from 8 stops or so with GH1 to 10 years later S1H with little under 13

It will be amazing to see true 15 stops on a DSLR . Best has been the S1H at 12.5 stops in video ,even the Alexa is only 14 stops

• Camera will have improved touchscreen functions
• Camera could do 4K streaming
• Sony can have delay up to 6 months of actual camera availability, expect it to be summer 2022
