Jintu 420-800mm Telephoto Lens Review (2023 Updated)

Welcome to Camlense. Today I will be talking about the Jintu 420-800mm Telephoto Lens which I call the beast. We have been receiving comments related to this camera, so we decided to review it on a detailed basis. So, if you are interested in it, continue reading.

Jintu Telephoto Lens Specifications and Features

Super Zoom

As this Jintu Lens can shoot in 800mm, therefore, you can get a very zoomed in photo, much likely like super-zoom. The zoom quality is much better from expectations.

Here I will show pictures taken with the stock lens (15-50mm) and the super-telephoto lens. The picture on the left is taken with the stock lens, completely zoomed out. The picture after it is taken with the same stock lens but fully zoomed in.

Now, you can see the pictures taken with the Jintu 420-800mm. The picture on the left is completely zoomed out and is taken with 420mm focal length. The one on the right is completely zoomed-in, taken with 800mm.

Another example of the super-telephoto zoom is this bird on the tree. Here you can see in the picture on the left, that there is a tree, but you can’t see the bird. With the super zoom, you will see the bird on the right side of the pic.

Manual Focus

This can be sometimes a plus point and sometimes a downside depending on your need. Professionals and those who want to be professionals, tend to use manual focus and overall manual settings as they want to take a grip on their cameras. So, they see it as a plus point.

On the other hand, hobbyist photographers which are not much familiar with photography and cannot do much in manual settings, then it’s bad news for them. Yeah! I know it’s easier to learn manual focusing but it’s missing. So, I am pointing it out.

Build Quality

The build quality of this lens was quite impressive. Previously I thought that this cheap Chinese lens would have a plastic body and won’t look expensive, but I was really impressed to see that this lens had a metal body and appeared just like the expensive ones. The build quality is no doubt amazing.

Affordable Price

The most important thing about this camera is its price. Who would go for Jintu instead of Canon or Sigma if they have the budget? Obviously, the one looking for this lens would be tight on budget and must be looking for an affordable lens.

The Jintu provides all the above-mentioned features for less than $100. Even if it’s missing some features or if it is somehow not comparable to the Sony or Canon, you should also consider that it’s cheaper than 1/10th of their prices.

My View About this Lens

Now it’s time to give my review about this lens. At first when I came to know about this affordable super zoom lens, I thought that this $100 lens might be like some plastic thing but it’s actually really sturdy construction. It’s made of metal and is pretty solid build.

The glass on this lens seems pretty decent as well. The lens also comes with whatever adapter mount you buy with it. If you have a Sony camera, you will have to buy one dedicated for that specific camera. You are able to mount this lens on a tripod and make whatever adjustments you need to make.

To use this, it has an open slider screw thing which you can just pull in and out to zoom manually. It is a manual focus lens, and the focus is just like any other lens having manual focus. I don’t think you can get pro quality with this lens because you will have to spend 10 times more on a lens for that. It does have a few uses though which are nice.

For example, if you are considering getting a bigger zoom lens but you don’t really know if you are going to use it that much, this can be a good lens for that. Only for a $100 you can practice with the lens like this. See if it fits your use or if you really need such a big lens or not before you go out and spend 2 thousand or 3 thousand dollars on a lens.

Another good use for this lens is that if you like to check some birds off your list and don’t want some really pro image quality, then this would be a fantastic lens for something like that. These lenses can also be used in spite of binoculars or monocular.

Photo Taken with Jintu 400-800mm Telephoto Lens

Now, let me show you some examples of using this lens so that you can see for yourself. Let’s take a picture of the Moon. I always wanted to take a good picture of the Moon. So, first of all, I am going for the Moon. I took some pictures of the Moon, and I would say, it’s not bad. You can see for yourself.

Moreover, you can also see the viewfinder and the zooming in this lens in Realtime in the picture below.

Problems With This Lens

Manual Focus Lens

The first thing I wanna mention is that this lens is manual focus, so it’s not super easy to tack a nice tack sharp image for a beginner without any experience with manual focusing. I would suggest buying this lens if your camera has to focus peeking or it will be too difficult to get a picture of anything without practicing the manual focus.

Dusty Images

The other thing that I wanna point out is that you’ll see in a lot of my pictures, the dust specks and this is actually pretty normal with the zoom lenses but with this lens, I think it’s a bit more. That’s something I think you can compromise with if you are paying just 100 bucks.
