全新騰龍70-300mm F4.5-6.3 Di III RXD A047鏡頭評測：做一支開心的長焦

I‘m holding a telephoto lens and acting like this If I can’t shoot an Animal documentary, I will just be Groot If I can’t be Groot, just put me alone in a pot and I’ll decorate my studio I’m counting on this lens to get me some nice shots today Yet another Tamron lens This 70-300 Di III RXD is a new lens from Tamron Another telephoto lens for Sony E-mount this year Really, I can’t even remember how many telephotos lens Tamron has released this year We have a 28-200mm released early this year Following by the 70-180mm Now, we have this Unlike other brands that choose to make their selection of lenses cover a wider focal range Telephoto lenses from Tamron deliberately overlap focal lengths to offer a wide variety of choices to users This lens has the similar Tamron formula Build quality and finishes are also familiar Its lightweight design makes this lens suitable for travel photographers All recent e-mount Tamron lenses have weather sealing and a fixed filter size of 67 mm It seems that Tamron wants to build an army of lenses all with 67mm filter size But what’s the actual performance and characteristics of this lens? We will test this lens out and have a definite answer at the end of this video What kind of photography is suitable for this lens? Welcome to Colorbee Photography I am Brian A lot of fans are worried about us living in Australia Fierce kangaroos might camp in your backyard Snakes might hide in your toilet Poisonous spiders might be in your house and kill you within half an hour Such a horrible place for life to survive Indeed, we have seen all those creatures before Therefore, we are waiting in our backyards to see if we can capture any of those creatures In our test today, we have this 70-300 with an also lightweight Sony A7C Apart from above we also brought a Sony 90mm for Macro shots See if we are lucky enough to get you a portrait for a spider today I also got a Batis 18mm in my bag which is my new favourite See if I can capture something interesting to share This lens only weighs 545g which is the lightest among all of our 300mm lenses As it just passed 500g you won’t feel the heft in your bag The size of this lens at 70mm is similar to a can of Coke It can then be extended like this The most common large animals among our studio are Kangaroos They are normally everywhere but we can’t find any of them today when we actually decided to take a few shots There are lots of Kangaroos in Australia with different varieties Such as those very big red kangaroos in the middle of Australia tree kangaroos in the north, and rock-wallabies The most common type of kangaroo that lives in Melbourne is the Eastern grey kangaroo Soft grey fur covered most of their body with white bellies Their heights are normally between 1.2~1.5m They look big, but are timid by nature Normally they keep about 30m away from humans even if you tiptoed quietly You can probably get their full-body shot if you are using 300mm lens The focal length of this lens can be extended to 450 mm under the crop mode In this mode, you can get more details like that in the thumbnail Comment below if you know what it is :) Best to share with everyone what’s the use of it :D Now let’s talk about its sharpness Previously, we tested this lens on a SONY A7R2 camera body We found this lens struggling a bit to fulfill the full resolution of 42 megapixels At 70mm focal length, the sharpness is decent But when it comes to 300mm this lens is kind of falling behind In particular, there might be slight color fringing along the edges To solve this, we tried to down-size the files from 42 megapixels to 24 megapixels or use a 24-megapixel camera strightaway The sharpness is then totally acceptable However I wonder if there are any A7R3 or R4 owners who’d like to buy a less-than-900-dollar telephoto lens Its image quality is undoubtedly worse than that of the 100-400GM lens But, truth be told, it is fairly competent for daily use I see a couple of wood ducks in the middle of the pond Wood ducks are aboriginal creatures of Australia And also said to be one of the fastest bird species in the world I’m here trying to take some close-up photos for you guys Now you listen to the chirp of noisy miner who’s protecting her nest by intimidating that cormorant Cormorant is loopy and unaware of entering the bird's territory Small as they are, noisy miners are rather fierce animals They often form small groups to expel larger birds that are trespassing their territory Such as Australian magpies, as well as crows I’m gonna get a bit closer Lotus and telephoto lens these are enough to make an old man’s photography good And I did get several surprisingly good-looking photos here I didn’t expect so beautiful flowers in such a small pond which is water lily to be exact in the right season of full bloom When we are shooting water lilies, I did found a small issue The lens is so compact and small that it has no optical stabilization The stabilization relies on the camera body Even at 1/250 seconds handheld images can still be occasionally blurry A 1/250 shutter speed plus a maximum aperture of 6.3 at 300mm focal length What do you make of that? It means I’ll have to step up the ISO when taking photos Now we with a cloudy sky let me check the ISO settings It must be set at 800 or higher to ensure a safe shutter speed with max aperture This is a bit disappointing There are frogs here And you may see bubbles in the water as well The first wave of tadpoles have already been hatched There are also frog spawns over there With this 70-300 on an A7C for handheld video shooting You may find the stabilization to struggle It’s trying to keep the subject steady in the frame But the focal length is just too long So some jittering becomes unavoidable which makes all handheld footage unusable Especially for serious work So, if you want to use this lens for video get yourself a unipod at least Mount it on a tripod to achieve the best result I’m now testing the macro capabilities of this lens I might be spoiled by the performance of previous 28-75 and 17-28 Tamron lens I took it for granted that this lens will also have powerful macro performance However, having tested it for a while, I found that it is not the case..... You may shot a bit closer at 70mm focal length But at 300mm, you’ll have to step back for about 5 feet (1.5m) To get a snappy focus on the object So, when shooting macros with this lens you should be aware of its limitations A remarkable feature of this lens is its coating for a decent anti-glare performance which is on par with its ancestors If you have to shoot in a backlight scenario even under direct sunlight Basically, you don’t have to worry about large-scale backlighting However, color fringing of high-contrast objects is still worth noticing Ah! Giant white! Cockatoo That’s the renowned cockatoo Often foraging in flocks in fruit season I’ll check it later to see if I get a clear shot of her I just walked through the grass and found many rainbow lorikeets They are the prettiest parrots as far as I’m concerned Telephoto lens are mainly for wildlife and sports photography When pairing with a camera that has a mediocre focusing system It works fine at 70mm But when you zoom in to 300mm The camera will be busy keeping the image stabilized while focusing at a max aperture of f/6.3 So focusing does feel a little bit sluggish And the way they designed the lens they didn’t leave a switch for AF/MF In order to change focus mode you will have to go into the camera’s menu system Also the focus ring is closer to the camera body then the zoom ring It’s not so natural for me to operate But as I said do you really want to count on the focus accuracy from a Sony camera viewfinder? Based on my experience it’s very probable to have spiders in this pile of bricks Please look out for me Ah! Box! Hand me a box! Look! How stunning! Absolutely beautiful Taking a “Portrait” with this 90mm macro lens Help me hold a flash! It can get as large as 15cm (6 inches) I’ve seen one this big Right under the lid of my house’s trash bin These spiders like to hide under car hoods behind the curtains and spots like that They are not annoying until they surprise you There was one time, one of my friends had a spider in her car’s sun visor It dropped on her lap when she flipped the sun visor She was just a hair close to jump out of the car Imagine a girl driving on the highway 100ish km/h(60ish mph) with a spider suddenly dropped on her lap 90mm macro just enough for a half portrait Guess how many eyes it has Two on the top and four on the bottom May I have a highlight on the eyes please It even has eyelashes Come on, come on Don’t be shy Turn around Look at me, don’t move Hey, perfect angle Let’s do a 45 degree Rembrandt light on it Look at those sharp eyes I am glad to show you guys all these wildlife near our studio today The wildlife in Australia looked bold and strong But they are mostly timid creatures This is just like Australians harmless and gentle for the most part Even though they might look bold and strong But that’s just a result of evolving in a harsh natural environment A way of surviving right? :) Let’s get back to the lens This 70-300mm Di III RXD from Tamron Didn’t impress me too much other than being very light-weight Overall performance is mediocre We checked the price before we made this video Its MSRP is $999 AUD But when I checked the price again right before we uploaded this video its pre-order price is only $890 AUD That would make this lens a real bargain Especially when Sony FE 70-300mm f/4.5-5.6 G OSS is priced just at almost $1900 AUD How much do you think will be a fair price? Since the prices in Australia are usually higher than other regions Leave your ideal price for this lens in the comments below Alright, who is this lens targeting for? Let’s take a look If you’re a full-frame 24MP user and already has Tamron 28-75 f/2.8 Di III RXD This Tamron 70-300mm Di III RXD can be a good extension to your telephoto range There’s one thing I have to mention even though this lens has image stabilization, due to its small aperture It’s a lens only suitable for well-lit environment If you’re going to on a photo shoot with kids to the zoos during broad daylight Or snapping photos for running kids on a sunny football field this lens will handle it just fine But if you’re an full-frame user who’s looking for an easy carrying telephoto zoom lens I think Tamron 28-200mm F2.8-5.6 Di III RXD would be a better choice If you shoot photos in a dark environment Tamron 70-180mm F/2.8 Di III VXD will be your best bet Like stage events or landscape photography that includes sunrise and sunset scenes Alright That’s all my thoughts on this Tamron 70-300mm Di III RXD Please leave your comments below if you like to see more videos from us We have links in the description below for those spider photos And you are more than welcome to forward those to your brave friends and have some fun Thank for watching, I’m Brian, and I'll see you next time
