Tamron 70-300/4-5.6 VC VS Olympus 40-150/4-5.6R

Zoom comparison today!
These are roughly equivalent field of views, given that the Olympus is a little bit tighter at the widest end with 40mm being roughly an 80mm FOV to start.

I picked these lenses because I think that when people decide to buy lenses like these, they are looking more at the equivalence in field of view, not the actual focal lengths.  Yes, there are going to be differences in depth of field and compression, but they are very similar in reach and how you will be able to compose with them.

While these might not be award winning images, they are more than enough to give you the idea of the sharpness and real world usage of these lenses.

The kit used:

Olympus OM-D E-M5
Olympus 40-150/4-5.6R bought used at $100

Nikon Df
Tamron 70-300/4-5.6 VC bought new $350

I went out to my local park and walked around and just started shooting.  Exposure wise, the Nikon and Olympus were pretty much dead on for every shot.

In the wider focal lengths, the IQ from the 2 lenses were pretty close, with only a slight end going to the Nikon/Tamron combination.

Where there is a larger disparity is when you get to the 300mm FOV.  The Olympus really started losing some clarity and sharpness once we got out beyond the 100mm focal length setting on the lens.  That is when we are pixel peeping at 100%.  How this equates into real world is a different matter as you'll see from some head to head examples.

 I almost never show images without putting my post processing stamp on them.  Once that is done, the gap between the 2 kits are narrowed.

I will say this, though....possibly in defense of the Olympus optic...I think the lightness of the kit is a bit of a detriment for shooting these longer lenses.  Without the weight for resistance, I think that I am having some issues adjusting to shooting this lens hand held out beyond the 100mm focal length.  Even with the IBIS, I am going to need more time to get used to shooting this lens at the long end.  I'm also wondering if the added weight of the HDL-6 Olympus grip might help add just that little bit of extra weight to give it a better feedback.

The Tamron was not without its issues either, at least in reference to my usage of it.  There were some test shots that the shutter speed was 1/1250 at 300mm at I forgot to turn the VC off.  There was some visible blurring of the fine details because the VC got confused.  For those unfamiliar, if you leave the VC on and put the camera on a tripod, the VC can actually introduce blurring because it compensates for camera movement when there is none.  I believe this same phenomenon occurred here.

So, just know that I am not claiming this test to be scientific....it is definitely more real world usage.

On the IBIS/VC note - they both worked very well and when needed, kicked in and worked great.

At the end of the day, and for the price, the 40-150 optic is very good.  It is also noticeably smaller than the Tamron/Nikon equivalent lenses in the range.  Using the same Maxpedition "Mongo" shoulder bag, I can fit the Nikon Df with the Nikon 24-85 zoom attached and the Tamron 70-300mm and that pretty much takes up the main compartment.  With the Olympus kit, I can fit the EM5, and all 4 of the Olympus lenses(17/1.8,45/1.8, 12-50,40-150) I own in the bag and still have room left over.  So, take that for what you will...all of you who are looking for a smaller kit.

When you look at a lot of the head to head shots, after the post processing is complete - only but the most picky of pixel peepers are going to be able to know/tell which lens/camera was used for these shots.

Just Amazing!!! The Tamron 70-300mm f/4-5.6 VC

Took a trip to the Cincinnati Zoo and decided to really stress out the VC on the new Tamron lens.  All I can say is that the VC not only works, but really surprised me in just how well it worked!!

I've had other VR lenses in the past and they have all worked well.

Look under the sample images below and check out the EXIF data.  Yes, these are not "fast" aperture lenses, but my goodness the VC on this thing is miraculous!!

Gear loadout was the Nikon D700 and the Tamron 70-300mm f/4-5.6 VC, attached to a BlackRapid sling strap.  No tripod, no leaning on a wall or pole for support.  Straight hand held.

1/60f/5.6 ISO 640 300mm

1/20 f/4.5 ISO 1250 125mm
The ones above, numbers wise are good, but check these next few out.  CRAZY!!

1/8 f/4.8 ISO 1250 160mm
1/4 f/4.0 ISO 1600 80mm
Yeah, 1/4th and 1/8th of a second.  Those are not typos and I'm not pulling your leg.  I did not doctor the EXIF info in any way.  I'm still a little shocked looking at the last 2 images and seeing the EXIF data numbers.

Tamron 70-300mm f/4-5.6 VC - Gear Review

As most follows of the BLP blog know, we have switched back to an all Nikon shop.  All the Fuji gear we had sold and the proceeds gone to the Nikon Df.

Tamron 70-300mm f/4-5.6 VC
Nikon 70-300mm f/4.5-5.6 VR
The Nikon Df will be our new take everywhere and travel gear.  To that end, we like to keep our travel and EDC(every day carry) kit to a minimum.  To that end we are going with 2 great zoom options.  The wide to medium telephoto will be the Nikon 24-85mm f/3.5-4.5 VR(on order and coming this week - review to follow) and the newly acquired Tamron 70-300mm f/4-5.6 VC.

 This gear review, we will concentrate on the Tamron lens and compare it some to the tried and tested Nikon 70-300mm f/4.5-5.6 VR lens, which was in tight contention with the Tamron.

Lets look at the this lens compared to the Nikon and why I chose it.

I was lucky enough to get into Midwest Photo Exchange and worked with Sonnie on comparing these 2 lenses.

What we had to work with:
Nikon - refurbished
Tamron - factory new

Test Platform:  Nikon D700

Size:  The Tamron was slightly smaller in length, but larger in diameter than the Nikon.  The Tamron has a larger lens hood as well.

Handling:  They both handled about the same.  Because of the plastic construction, the zoom was a little sticky at times on each.  Nothing like the pro 80-200mm f/2.8 or the 70-200mm VR lenses...but then again, we are not even in the same price range or size here.

AF speed:  Slight advantage to the Nikon, but not by much.  Sounds wise, they were both whisper quiet.  They both also have the full time manual override of the AF, just by turning the manual focus ring.

Optical quality:  Pretty close to even, I don't think I could give a nod one way or the other.  They both were very good.

Image Stabilization:  Both worked as advertised.  I was getting relatively good hand held shots in the shop at 200mm, f/5.6, 1/25 and 1/50 of a second.  I did notice a little different "activation" of the VC compared to the Nikon.  Not better or worse....just different.  Noise wise, the Nikon VR was more noticeable, but only from the shooter at the camera.  In real world application, no one would notice.

Other Thoughts:
I own/have owned other Tamron lenses in the past and they have all performed very well optically(Tamron 17-50mm f/2.8 and Tamron 90mm f/2.8 Macro).  I'm not opposed to using their lenses on professional shoots at all.

FYI - The sample images I took were either from my back yard or from Slate Run Living Historical Farm.

What swung me to the Tamron:
  • f/4 at 70 on the Tamron versus f/4.5 on the Nikon.  It doesn't seem like much, but when these lenses are that close you start to get really nitpicky.
  • Price.  Midwest Photo had a refurbished Nikon($386) or a new Tamron($449 - $100 mail in rebate = $349).  Slightly better price, nod to the Tamron(6 year warranty is great as well).
Some things I'll need to get used to:
  • Weight.  I'm so used to the weight and size of the Nikon 80-200mm f/2.8 that this thing seems very light.  Not a bad quality for a travel/take everywhere  telezoom.
  • Zoom/focus ring switched.  Every lens I'd had up to this point have been the more traditional zoom ring closer to the mount and the focus ring toward the front of the lens.  Both lenses were designed that way, so it would take some adjustment either way I went.
