Has anyone ever encounter this issue before? I tested out my new lens which is a APS-C lens for Sony E. It's the Sigma 56mm F/1.4 DG DN C. When indoors aiming the camera at a white ceiling with the shutter at 1/15th is when I can begin to see the green cast creep up. It gets deeper as the shutter goes up. I notice this strange green cast when looking through the viewfinder. A member of this forum suggested that I turn off shading comp. I did, and the green cast disappeared. I would like to know if this is normal with this lens, and what exactly causes this strange phenomenon? I tried looking it up, but could find nothing on it. Here's a photo that I took with my phones camera placed in the viewfinder.

That's great to know, thank you so much. I haven't tested it out outdoors in daylight with those settings, but I'd imagine that green cast would have an affect on the color.

Thanks for the concise information. I wonder how they will fair when they introduce the new curved sensors.[COLOR="Silver"]

That worked thanks. What happens when I select lens profile in Lightroom? Will the green cast come back?

Thanks for the clarification. I wouldn't be surprised if it did have any issues. With the shortage of workers and supply.

Yeah I'm excited and eagar to try something new. This should be a significant jump from what I currently have. I'm ok with it not having 8K. Not many people have 8K displays anyway. I guess it would have been good for future proofing. 4K is good enough for me. I'm not exactly sure what you mean by bleeding edges. I'm only aware of that term with monitors and TV's. Are you talking about the display it'll have? If that's the case that won't bother me too much. As long as I'm not seeing that in the viewfinder. I'll be ok. Hopefully, the user menu has been improved. I hope one day we'll have insect eye AF. I know that sounds crazy, but I believe it'll happen eventually. Assuming we all survive the next calamity to come.

Going with the A7III will only save me $689.51 that's not enough money for top glass. I'm better off with the newer camera that's coming out. If you buy right you won't buy twice. Buying the A7IV and a needless A7III will cost me 4,310.49 I'm better off spending that $1,810.49 on a top piece of glass. One example I could think of is the Sigma 35mm F1.2 Art DG DN lens. *

Does anyone know if this is normal? I brought this Sigma 56mm 1:1.4 DC DN last month. Upon settings out some of the testings indoors I noticed the strange green looking flare with my shutter set to 1/2000 ISO 100 aperture set to F/1.4 Aimed at ceiling with no direct light hitting it.

Thanks for the refresher. I'll likely upgrade the A6300 as a secondary camera when I feel a worthy successor is available. My cup is half full for Sonys faith in APS-C cameras. They really need to improve upon the dynamic rage, noise control and color science.
---------- Post added 02-11-21 at 10:29 AM ----------
Sounds interesting. I know the benefit of mirror sensors is lower noise. digital mirrorless sensors tend to add noise due to the sensors needing to always be on to function. As well as a few other things. I'm not going to mention as I'm sure you already know this. I wouldn't rely on DxO bench marks. Lens rentals is far more accurate imo.

I'm not sure where you got the impression that I wasn't intending to use my APS-C camera for wildlife. When I stated that I'm done using it for landscape, portraiture, and events. Sony does have a 70-200mm F/2.8 GM that would be 105-300mm on a APS-C body. With a 2X TC it would become a F/5.6 in aperture. Than again with a higher aperture the photos should be more sharper. The noise control on the A7IV should be more superior than the A7R series of cameras. So I likely don't need to revert from mirrorless to DSLR. Also if I need more reach I can always use a feature called clear image zoom that doesn't affect the aperture at all.

"bigger pixels, more light per pixel, theoretically lower noise, lower pixel" If that's the case than why does the A7III outperform any A7R, A9, A6xxx camera in the noise department? No I don't see 24MP outresolving old glass and I believe it would be fine on a 32-36MP A7IV. Also the A7IV information was leaked by a trusted source that was spot on with his A1 information. The A7IV is expected to be around $2,500.00 Likely will be a little less with my student discount access.

"Generally apsc cameras have that not the ff" That's not true at all.
I'll give you the latest example. The A1 is capable of shooting at*30 fps*with no blackout.

Sony doesn't make a 600mm that has a aperture of f/2.8 They make a 600mm F/4 prime that is 13,000.00 While I could save a little and buy that lens. I'm not interested in spending that much money on a lens. I've been using the A6300. I'm done with APS-C cameras. I'm ready to move on to a better more supported format. I'd go over what I'm tired of with APS-C cameras. However I feel it would be like debating which religion is right. You're content with your format and I'm not content with it anymore. There's no convincing me to stick with a format that I've lost interest in. I don't like it for landscape and portraiture. Let alone for tight event spaces. I don't like not being able to see my vintage glass the way it was intended to be seen. You could say than use a focal reducer but that degrades the photo quality. It also changes the character of the bokeh. Giving it a unnatural swirl that I don't want to see on a lens that isn't suppose to have swirl to begin with.

I've used a APS-C camera for years, and have dealt with all of the shortcomings of using a cropped sensor. I want better features, better bokeh, better low light capabilities, better noise control, faster AF, and Faster FPS. I want to be able to use any FF lens, and not have to worry about what the aperture is going to be, what the actual mm is, etc. I understood what UncleVanya meant. I just don't feel it is worth wasting a extra grand on a 2MP difference when I already have a APS-C that I can use for more reach, if need be. The teleconverters slow it down to f/9 and f/13 respectively. Autofocus still works, but struggles under dull lighting. If you want to boost the range, you’re really better off mounting the lens on an A6xxx series APS-C body, which gives you an ‘effective’ 300-900mm zoom range. I also don't want to spend money on older tech when the newer A7IV will have updated specs. The A7IV will have better AF, and be an overall better camera for my purposes. The only thing the R series has going for it is MP. The MP of the updated A7IV sensor is more than enough for my portraiture, wildlife, landscape, and event purposes. I also dislike the noise those higher MP cameras tend to introduce. Than you have to waste more time in post degrading the photograph to mask the noise. Also, keep in mind that I like to adapt vintage glass. It would be counter intuitive to handicap my collection by allowing those lenses to be outresolved on a 60MP that is useless for my purposes. I don't believe more MP equates to pro quality. Sadly most users have that misconception. Hope I'm not offending anyone either. That's not my intentions. I'm just stating my honest opinion. Thanks for the lens recommendations.

I figure it beats the average paid sponsor Youtuber that recommended the $1000.00 tripod that only weighs 4LB, lol. I also lift weights so before anyone comes in and says "but it weighs 18LB!" Go eat a banana.😋

Thanks for the recommendations. The 100-400 isn't as sharp as the 200-600. Also using the 100-400 with a 2x teleconverter isn't viable when your losing a lot of stops of light and degrading the image with the 2x teleconverter. Let alone having to push the iso higher to compensate for that loss of light. As well as loss of AF features. Paying an additional grand for 2 extra mega pixels isn't worth it for me. Also having to pay for expensive storage for the larger files isn't worth it either. No one is going to notice the 60MP online. I don't have any intention of printing anything larger than a football field either.
---------- Post added 02-11-21 at 06:43 AM ----------
Unfortunately there isn't a 200-600mm native to my camera mount. I wish they made one instead of wasting time on a basic 70-200mm as if the market isn't over saturated with that focal range already. Thanks for the lens suggestions.

Hello, everyone! I want to get my first full frame mirrorless camera. The budget is $7,000.00 I can add more if need be, but I would like to keep it at $7,000.00. I'm leaning on the A7IV camera body. To save some money I'll be using student discounts, and may also consider buying the items in a tax free state. Currently, the only FF AF lens I own is the Sony 90mm F/2.8 G Macro. I also have some vintage lenses that I enjoy, such as my Super Takumar 50mm F1.4 8 element, Super takumar 200mm F/3.5, Carl Zeiss Sonnar T* 135mm F/2.8, and a few others. Mostly in the 50mm to 135mm range. I would like to purchase the Sony 200-600mm G for $1,698.20. I'll be using that for wildlife. I may keep my APS-C camera for that lens for closer reach if need be. Instead of purchasing the 1X TC. I also would like to purchase the Sigma 24-70mm F2.8 DG DN Art for events. I haven't checked yet what the student discount would be, but it's currently going for $1,099.00. I really would like a 50mm, but I'm a bit torn with this decision. I really would like the Sony Planar 50mm F/1.4 ZA for $1,242.04. However, after watching and reading a lot of reviews the main drawback is with the AF. It's not quite as good as some of todays offerings. I'm not sure if I should go with that one, or pick something else. I also would like a good wide angle prime in my kit for landscape. I was thinking of the Zeiss Loxia 21mm f/2.8, and yes I'm ok with the wide angle being a MF lens for landscape. I really like the compact size of it and the weather sealing. I don't have to get that particular lens new. As I have seen them go for $800.00-$700.00, or best offer. Another lens I would like to add for landscape purposes is the Contax Carl Zeiss Vario Sonnar T* 35-70mm F3.4 MMJ.

Thanks for the suggestion. However when I looked at the three major sites for camera gear. I couldn't find any Manfrotto C-Stands. Would you mind providing a link?
