New Wildlife lens

Just the other week I took a trip to Cabilla woods in the Glynn valley to try and get some pics of  Silver Washed Fritillary butterflies, they are something that I have not had the chance to photograph before and I found out , much to my dismay just how ‘flighty’ these butterflies are!

I usually use my trusty NIKKOR 105 2.8 Micro lens for jobs such as these but the 105mm reach meant invading their privacy and subsequently sending them packing.

On the way back to my vehicle I decided to explore another area in the same vicinity with a lovely track up through the wood, after reaching a dead end I turned and headed back down the track only to meet a Fox coming up towards me! I immediately dove into the long grass at the edge of the track and poised my camera ready!

As mr Foxy approached I popped off a few shots which drew his attention towards my direction and he paused for a moment before he worked out that the clicky thing had a human attached at the back of it , of course he then turned tail and made off pretty sharpish.

I was totally beside myself with excitement for finally I had some pictures of a Fox something else I have always wanted to get images of. It was then I decided to check out the pics on the back screen of my camera , WOW this is going to be amazing! finally some seriously foxy images!!………………..I’ll just end this paragraph here, as it was at this point my heart sank with disappointment as in my head I felt like I could have reached out and touched the Fox from where I was, the reality however was that the Fox was too far for a good image with the 105mm.

My mind was set , I needed a good long telephoto lens for these kind of situations, I could not let this happen again.

Moving on a week and a bit of research and taking into account budgets , I decided on purchasing the Tamron SP 150 – 600 mm lens

tamron 150600

This lens is a monster, it weighs in at nearly 2kg and although made mostly of plastic, it feels solid and the build quality and finish are fantastic. It isn’t fully weather sealed but does have a gasket to seal between the lens mount and the camera body. The focus motor is silent and the minimum focus distance is 2.70 meters.

In the box you get the lens and the lens hood but no pouch or case! (come on Tamron!) why on earth they did not include one is beyond me.

It isn’t a particularly fast lens and may require a bump in ISO to get a fast shutter speed but it does include image stabilization or VC (Vibration Compensation as Tamron likes to call it) so hand holding is possible but I much prefer to use a tripod. It is not a fixed aperture lens and it ranges from f5 at 150 mm to f6.3 at 600 mm and I wouldn’t say the focusing is especially amazing or speedy but for the most part it works well, my copy needed quite an adjustment on my Nikon D7100 body as it was front focusing a fair bit but nothing overly drastic.

Let’s talk about the image quality

To be completely honest my first test shots in the garden (as they always are with me) left me with mixed feelings , obviously everyone wants to know how good it will be at 600 mm which is exactly what I wanted to know , well it was OK but it could be better, this was my initial thought. To be fair it wasn’t the best weather , quite gloomy actually and grey……..

Move on a couple of days plus a focus adjustment and a few local trips out in the sun later and I am feeling quite different now.

Broad Bodied Chaser Dragonfly (male)

Dragonflies are now so much easier to approach and photograph without disturbing!

As are birds……..

I even managed this next shot of an Emperor Dragonfly which I was so happy with! (this was manually focused)

How about an Owl in flight? In the daytime?……..Ok, it was a falconry display at Woodlands Theme Park in Dartmouth but hey!

Silver Washed Fritillary

This lens for the money is very capable and has opened up many more photographic opportunities to me, it is sharp enough when stopped down at f8 or f11 but obviously this then means bumping the ISO up to keep a fast shutter speed which introduces more grain to the image and requires a bit of time processing in your editor to get a cleaner image.

The Moon shot at 600mm and has been cropped slightly

Tamron have recently released the new generation 2 version of this lens which has a few tweaks to the optics to improve quality further. You may like to look at that version if money is not an object, but for me , the earlier version was the choice and I am content with my purchase now I have seen what  can be achieved with this lens.

This lens retails at around £750 in the UK and when you consider the ‘reach’ this lens will give you, coupled with the fantastic build quality, it certainly is worthy of consideration if wildlife is your game.

Oh and when me and Mr Fox cross paths again I will be ready……………

Sigma 50-100 f1.8 DC Art lens review

 

When it comes to weddings and portrait photography there is one lens you can guarantee every photographer will have in his bag and that’s a 70-200 f2.8 of some sort or another, the Canon and Nikon versions of this lens are simply stunning when it comes to image and build quality. But, what if you don’t shoot with a full frame sensor and want the equivalent focal length for your crop camera? what do you do then? none of the big camera manufacturers really cater for us crop sensor users……that is until now!

Introducing the Sigma 50-100mm f1.8 DC Art lens

The Sigma 50-100mm f1.8 DC Art lens

 

I was in just that situation recently, I currently own the Nikon D600 and D7100, the D600 being full frame (FX) and the D7100 being crop frame (DX). I needed something in the 70-200 range but didn’t want to be swapping out lenses on the full frame all the time, especially when shooting a wedding! so after seeing that Sigma have produced this 50-100mm f1.8 for APS-C (crop) sensored cameras, I thought I must try it, as this would give the equivalent focal length with the crop factor as a 75-150mm which is close enough to the 70-200mm range I was looking for. If you were shooting two crop sensor bodies this would pair up lovely with the Nikkor 17-55 f2.8 lens, giving the near perfect combination of wide to telephoto focal length for a wedding or portrait shoot, just something for you double DX shooters to think about…..

100mm f1.8

 

I am so pleased I did go for it with this lens and to be completely honest I have been blown away by the performance of this lens for the money. The sharpness at the maximum aperture of f1.8 is unbelievable for a zoom lens, you can really blow the background to a creamy blur. At f2.8  make sure you are wearing gloves because it’s incredibly sharp , It peaks at f4 , anything beyond that and you really wont be able to discern much difference. It has an 83mm filter thread at the front element, which will unfortunately mean purchasing new filters for some people , it really is a big piece of glass but the design is beautiful. Well done Sigma!

100mm f1.8

 

The build quality of this lens is SOLID!! It is of a full metal construction and weighs in at a whopping 1.5kg, so it is a very heavy lens. To the left of the barrel is the manual / auto focusing switch, that is the only switch as there is no image stabilization on this lens.

It comes with a tripod collar which some reviewers have said “gets in the way”,   I can say from my experience I didn’t find this to be a problem but I would have maybe liked it to be a little larger if anything, to use it as a hand grip but like I said before it’s no biggy. This lens is without a shadow of a doubt built to last, with one major flaw, there is NO weather sealing or proofing on this lens, which I myself find surprising as they have put so much effort into all other aspects of it.

The autofocus works well , maybe not quite the fastest but it is practically silent and accurate which is always a welcome bonus. The manual focus ring is large and to the front of the lens and is smooth and firm with absolutely zero play in it! which again is just how I like it. One other big thing with this lens is that it is a parfocal lens which means it will hold the focus point while you zoom in and out, this will be an added bonus for any videographers thinking about buying this lens.

50mm f1.8

 

The lens can be purchased in the U.K for around £800/900 which isn’t cheap by any means but in comparison to the Nikon and Canon 70-200’s this is quite some price difference. There simply isn’t another DX lens, offering this focal length and quality, anywhere.

This certainly is a lens worth looking at if you are in a situation like I was, It has proved itself worthy with me already for shooting weddings and portraits and general work. I am certainly not going to be letting this one go for a long long time…..All in all this is a first class lens that will fail to disappoint and one worthy of being in any DX shooters bag!

Pros:-    Sharp wide open           Cons:-    No weather sealing

               Extremely sharp at f4                   Autofocus not blazingly fast

               Extremely well built                     No image stabilization

               Great Dx focal length

               Good price
