Is it at all possible for me to set an ISO value, for example between 400 and 800?
Not on the D3400. It is on higher end cameras.
If not, why does Auto mode seem to have more control over the ISO than the other modes?
Because Nikon decided to implement it this way. The are two arguments for this, both of which are probably somewhat true:
The D3400 is ...
This is not right. I'd try Nikon again. Explain that you understand that the battery is a consumable that might not be good in a year, but that it is brand new. If that doesn't work, take it back to the store you bought it from. And if that doesn't work, open a dispute with your credit card company (on the grounds "they sold me a lemon and won't take ...
The first thing you want to do is to check that the pins on the foot of the flash match the contacts on the hotshoe of your camera. They need to match in both the number of pins and placement so that the pins will touch the contacts exactly. Most sellers will show a picture of the foot of the flash. See also:
Is flash brand X compatible with camera brand Y?...
Apparently (though not actually apparent) you have to install the profile for your camera first.
Here is the answer I got from the help desk:
go to "Get More tab (usually shown at the right side with an asterisk)
Camera Profiles > click "Free" for Model of your Camera > proceed with the installation.
Before I finally got ...
The possible reasons for such behavior can be:
You preview the images you take too much. Using the LCD screen can
exhaust the battery
You use too much live view. Again using LCD is not good for battery
Your lens have image stabilization and you half press the
shutter too long.
You have defective battery
Here's a link to Neewer's website. I did a search for the VK750 ii and this was the only flash shown: https://neewer.com/?s=vk750 Apparently, Neewer has given this Nikon-compatible flash its own unique model number as the one for Canon has its own unique model number.
Generally, this is how you can determine if a flash is for your Nikon:
Since each ...
The Neewer VK750 II is very compatible with the Nikon DSLRs (iTTL, in the last ten years), including the D3400.
This Neewer VK750 model appears to be a relabeled Meike MK-951.
It is a good choice and a good flash, however, it is not one of the fully powered flashes (like Yongnuo for example), but it is comparable to the power level of a Nikon SB-700 ...
There is nothing to "fix". This lens has no electrical connections to be made to the Nikon D3400.
Because there's no electrical connections to be made, the camera doesn't even know there's a lens attached, or determine the type of lens attached. Thus, you have to set your camera to Manual exposure mode, and set ISO, aperture, and shutter speed yourself — ...
Do I need to make any changes to Lightroom before I try this with the RAW files, please?
Yes. According to Adobe's page Cameras supported by Camera Raw (also known as Adobe Camera Raw, or ACR), for the Nikon D3400,
Raw image filename extension: NEF
Minimum Camera Raw plug-in version required: 9.7
Minimum Lightroom CC version ...
Which camera and lens combination is better for casual use as inferred from the question is probably irrelevant. Their performance in most respects should be close enough not to make a huge difference.
However both combinations have a clear edge each.
The Canon has a more versatile lens with much greater zoom range. This will be a blessing outdoors.
No, it is not possible. The D3400 does not have wifi, which is required for Snapbridge-enabled cameras to be controlled by the remote smart device.
From Nikon Europe's product page for the D3400
The D3400 makes it spectacularly easy to shoot and share DSLR-quality images. Nikon’s SnapBridge¹ keeps the camera connected to your smart device via Bluetooth® ...
No there are not. The reason is simple mechanics.
Canon EF uses a 44mm registration distance with a 54mm throat diameter.
Nikon F uses a 46.5mm registration distance with a 44mm throat diameter.
The registration distance is the distance between the film/sensor plane and the lens mounting flange. The throat diameter is the width of the hole in the middle ...
Based on experience with non-identical but similar hardware, I would suspect you have the controller set to TTL.
For a manual lens, you need to be in Manual mode on the controller, on all groups, whether they have a linked flash or not.
I would assume this is because the lens cannot be stopped down to measure the light, though it would be interesting to ...
According to the manual, shutter-release is disabled because:
Memory card is locked, full, or not inserted (P 13, 292).
Release locked is selected for Slot empty release lock (P 226) and no
memory card is inserted (P 13).
Built-in flash is charging (P 38).
Camera is not in focus (P 35).
The attached lens is not type E or G and the camera is not in mode M
SnapBridge version 2.5 (and up), allows for Remote Control over Bluetooth (in addition to remote control over WiFi). E.g., D3500 doesn't have WiFi either but Remote Control is possible with SnapBridge (https://nikonimglib.com/snbr/onlinehelp/en/05_remote_02.html). HOWEVER, for reasons only known to Nikon, it doesn't make the same available for D3400 (I guess ...
If such an adapter exists (and it probably does) you will lose infinity focus due to the canon eos mount having a smaller flange focual distance. You will also most likelly loose autofucus and aparture control (lens will stay at full open).
On the other had this is the same lens type still used on canon DSLRs today so if buying a cheap used canon body (can ...
It seems, for whatever reason, that your camera can not detect when the flash signals a confirmation that is is charged and ready to take a shot. This may be an issue with the confirmation circuitry, or it may be an actual issue with the flash itself that prevents the capacitors in it from charging or otherwise prevents the flash from functioning properly.
