Great i am glad that you find a99Ii could replace your a900

I borrowed Sony CZ 16-80 APS C lens and as sony says the lens work with all sensors.

MY SONY16-105 APS C lens work only with 79 af points as Sony stated

How is the image quality?

What about high ISO/Low light performance?
There are people who actually think LENS stabilization is better than sensor shifting!

Thanks Rex, you have helped me make my mind up. I was tempted to sell all my gear and switch to an A7Rll setup but I am now just going to get the new A99ll. Anyone know what I will get selling my A99 with low shutter count? Cheers

as mentioned in another post,  i have today ordered the A99II also,   alas i am going to have to sell off some of my other gear to help fund it,  in particular my A700 and A77,  both low shutter counts.  Not sure what they would be worth here in NZ, unfortunately all the negative talk last few years about the A Mount being a dead duck could make it harder to sell them.  (would be  a shame if i did have to keep them )

The EVF was very nice, clear and flicker free - I could definitely use it as a replacement for the A900 OVF.

Overall, thumbs up, and i need to start saving... :)

Rex,  you have had the A99 for a while now,  what are your impressions now?  Still waiting for mine to arrive,  cant wait, but guess i have too.  There are a few reviews starting to appear on line,  lots of positives,  but also some negatives,   however doing a bit more research on those doing the reviews - they all seem to be done by Nikon or Canon Photographers and we all know what most of them think of Sony gear fullstop. Most are saying impressive camera  BUT - they all still seem convinced the alpha mount is dead,   only time will tell i guess.

I have an A6000, which has an EVF - and while I appreciate many of it's benefits, I would still not hesitate to choose the OVF on my A900 in preference to it.

The A6000 EVF is good, but I am still aware when using it that I am looking at a digital image of the scene, not the actual scene - with the A6000 I prefer to view the scene, then raise the camera to my eye to take a shot - with the A900 I am happy to watch the scene through the viewfinder.

When I tried out the A99II I found the quality of the EVF was sufficiently increased it was almost indistinguishable from looking at the scene through an OVF, which meant I was happy to watch the scene through the EVF, and that was the target I was looking for.

Yep.

This generation of EVF as well as the improved proved processing that powers them is as good as the best OVF available... at least in MY opinion that is the case. ;)

Hi BrianNZ i am still at work but yes i have it now for a while and believe or not is the only camera i use not because is new but is almost everything you need to take a photo.

I am still testing the a99II and and i have taken a lot of pictures with various lens. Last weekend i was using a99II with Minolta 11-18 vs a7II with 10-18. Both cameras in APS-C mode off and you will see the difference when i post them... after tomorrow i am on Holiday so will find time to post.

First think must be done on camera is MF adjustment. This is a must. With the high resolution pictures and fast lens you need MF adjustment. Better not to go out to shoot and stay home and adjust the camera.

All lens i used until now they were MF adjust except the wide angles.

70-400GII-300G-300G+2x. With the teleconverter i was not very happy but i will adjust again and retry.

70-200G is not yet adjusted and must say it need adjustment.

The best performance i got with 300G. This camera is like it belong to be attache on this lens. Even at 2.8 you get amazing results even in APS-C mode on. The view finder is full of AF sensors and you cant move your AF points where you like.

I extract some photos from video and i can say they are acceptable. You can play back in slow motion and select the desire frame and extract it but is not comparable to the photo frame. Maybe is comparable to photo frame from other manufactures :)

As i said i am still at work i will try even tonight to post some pictures all Jpeq until now.

thanks Rex,  as a bit of an armature i have read but never done any micro focusing of my lenses. probably something i should have done.  i have read the manual for the A99II regarding this and i am not quite understanding it.  Can someone please explain to me in a bit more detail what exactly it is and how to do it, or will it become clear when i  get the camera and try it.  i will only have three lenses to do, as i am selling all my others ,  the ones i will be keeping are the SAL2470Z, SAL70400G  and my Tamron 90mm Macro.   In the research i have done i found someone that had calibrated their lenses with the A77 ,   they had my three as well as others,  he mentioned the two Sony lenses didnt need any adjustment but the Tamron need a - what he called massive adjustment - of -9.  would this be the same for all cameras or is it a camera by camera thing. One other thing that does concern me a bit is the loss of focal length going to a full frame -  i have read that my SAL70400G on the A77 would be like a 600 - that being said does anyone use teleconverters,  how easy are they to use.  My understanding is the Sony one will work with the SAL70-400 but only in manual focus,  that will make it hard for taking photos of birds in flight,  something im gaining an interest in - any comments appreciated.

Regards   Brian

The Micro AF adjustment is for trying to remove the tolerance in focusing with AF.  As there could be a variance of X+/- in the camera's AF module and in the lens Y+/- which these two tolerances combined are sufficient to move the actual plane of focus in front or behind the actual focus point.  Some lenses and camera bodies may be lucky and not need any adjustment while others will need some adjustment.
There seem to be different schools of thought in which is the best way to determine the required adjustment.

This may seem like a silly question but... shouldn't that problem be moot when using focus peaking? Since we are looking at what the imaging sensor ACTUALLY "sees" is "in focus"?

The effect of using a lens on a body with an APS-C sized sensor vs a FF sensor is one of the worst things for misinformation on the internet!

The Focal length of a lens DOES NOT CHANGE when you put the lens on a different body, it is an optical property of the lens.

What does change is the Field of View - IE how much of the scene is visible.

The smaller sensor only 'sees' part of the image, IE it 'crops' an image from the full image (hence APS-C cameras often being called 'Crop' bodies).

The reduction in Field of View is such that you get a Field of View equivalent to that for a lens with a Focal Length 1.5 times that of the lens - So on a 400mm lens you get the field of view as if it were a 600mm lens.

There is an apparent increase in magnification as if the focal length were increased as the viewfinder shows the image applicable to the sensor size - but all you are seeing is a crop (though this may be useful for aiding focus on distant objects).

There is also an apparent increase in magnification on viewing the resultant image - and this is where direct comparisons become more complex, as it depends on the specifications of the two sensors.

If the FF & APS-C sensors have the same pixel size (EG A900 & A700), then there will be no difference between an image shot on the APS-C camera, a shot from the FF camera in crop mode, or a post processing crop of an image from the FF camera to match the APS-C resolution.

However, APS-C cameras often have smaller pixels than FF cameras, IE an APS-C crop from a FF will be lower resolution than the shot from the FF-Camera.
This gives an apparent magnification for the APS-C camera BUT you get a similar apparent magnification comparing a FF shot on an A99 (24MP FF) to that on an A99II (42MP FF) - if you crop an A99II image to 24MP you get a more 'magnified' image than the 24MP image on an A99 with the same lens.

The A99II in APS-C mode is ~17.8MP, so you would 'lose' a little compared to the A77, but nothing like the 1.5 x that the simple 'FF vs Crop' conversion appears, and the benefits the A99II gives would easily outweigh this, I suspect!

Brian, Here is a post I made regarding Micro Adjustment of lenses on the A850, which in principal, will still be true of the A99/A99II/A77/ A77II. Since that time I have made minor adjustments to the Micro Focus shown in that post, particularly the Minolta 500mm F/8 reflex = -16.

A 45o Test card similar to what I used is shown here with instructions on how to use it. It can be downloaded and printed out. I printed mine out on heavy card and mounted it on a 45o wooden support. Mounting the camera on a sturdy tripod and using the two second delay is a must.

All Sony semi pro and pro level cameras, from the A850/900, including the A7 series and A77/A77II and possibly others, have a menu setting that lets you enter the Micro Adjustment. It should be noted that it is considered by some to be quite normal (preferable?) to have a slight back focus. (The range of acceptable focus is 1/3 in front of the focal plane and 2/3 behind.) This is entirely up to the user.
