New Lens Day Woo Hoo !!

The day has finally come my new Canon 500mm mk2 lens is due to be delivered today, I am meeting up with the previous owner to do the deal !

Upon inspection it is in near mint condition, complete with flight case and all the bits and bobs that go with it.
Like a buffoon I forgot to bring an Arca Swiss plate with me so all the shots I took with it are hand held, and I must say I am very impressed with the results.
We met up at Bossenden Woods coldest day of the year so far but hey ho!

These were all shot using Canon 5dmk4 and the Canon 500mm f4 L IS MK2

Coal Tit 1/250th @ f7.1 ISO 640

 Robin 1/125th @ f7.1 ISO 400

 Nuthatch 1/400th @ f7.1 ISO 640

 Nuthatch 1/320th @ f7.1 ISO 400

Blue Tit 1/320th @ f7.1 ISO 400

Nuthatch 1/320th @ f7.1 ISO 400

Nuthatch 1/500th @ f7.1 ISO 400

All the above shots had varying amounts of exposure compensation applied so as to retain the detail in the white bits on the birds.

I am over the moon with this purchase its an outstanding lens one that I thought was out of reach for me, I look forward to getting it on a tripod to see what it can do.

New Long Lens

OK so after lots and lots of looking and soul searching I came up with a shortlist, and it was a very shortlist.
Two possibilities:

Sigma 500mm F4 DG OS HSM Sport or Canon EF 500mm F4 L IS ii USM

Both very similar in weight and appearance, both come highly recommended, I have read tons of reviews about both lenses and they are so closely matched to each other there is hardly anything to choose between them.

Even on image quality its a close run thing with the Canon just edging out the Sigma according to the reviews.

Where there is a significant difference of course is in the all important cost, Canon currently selling for £8199 with a best ever price of £6139 and the Sigma currently on the market for £4690 and a best ever price of £4068.

I could not find a secondhand Sigma on the market, secondhand Canon's are currently around the £5500 mark obviously depending on condition.

I had therefore decided to plump for the Sigma as it comes with a 3year manufacturers warranty and being brand new I was thinking it would out last me as I am not getting any younger.

With the choice made I sat back and was watching prices daily, waiting for the Sigma to drop as at the time it was £4999 which is a little steep for me.

During this time I happened to mention to a fellow togger what I was doing when he informed me he would be getting a Canon 600 mk3 in the not too distant future and his 500 mk2 would be up for grabs as he would no longer need it.

I said that even secondhand it would probably be out of reach for me he then told me he would want £4000 for it !!

I said you are stitching yourself up you could easily get £5000, but he is happy with £4000.
So whats not to like I snatched his hand off and have agreed to purchase his Canon EF 500mm F4 L IS mk2 as soon as he gets his 600mm mkiii.

This is the best scenario for me being all Canon again as I only use Canon DPP for editing and all the Lens parameter's will be available.

Just have to wait for his new lens to arrive ! can't wait !

Restharrow Scrape

Restharrow Scrape is a good place for birding you never know what your going to find on the scrape itself, but also the surrounding area has some great habitat for a wide variety of species.

Early misty morning looking out across Restharrow Dunes

Whilst talking to a couple of visiting birders I saw one glance up, I followed his gaze and got this lovely shot of a hunting Kestrel

5dmk4 @ 1/2000th iso1600 F6.3 400mm

 I also dialled in +1.33ev to account for the bright background.

A short walk up the Ancient Highway towards the Chequers Inn I got these shots of Stonechats

5dmk4 @ 1/3200th iso400 F5.6 400mm

5dmk4 @ 1/1250th iso400 F7.1 400mm

Turned out to be a bit of a Stonechat fest, I did see Goldfinches, Robins, Linnets Great Tits, Blue Tits but they were to distant for good pictures all in all an enjoyable few hours.

 

The Murder Of Mary Bax

So I am out early walking between the Restharrow Scrape and the Chequers Inn I left the road as a bird was perched in a bush and I thought I would get a little closer only to stumble upon this headstone completely by chance and thought I would document what I have discovered about this sad event.

The inscription reads:

On this spot August 25th 1782

Mary Bax Spinster Aged 23 years

Was Murdered by Martin Lash, Foreigner

Who was Executed for the same.

I did a quick bit of investigation and the story goes like this (all though there are a couple of versions I believe this to be the true version),

The Ancient Highway was once the main route from Deal to Sandwich,  there were a number of buildings along the road, The Chequers Inn being one of them.

Mary Bax was a young woman of 23, on the morning of 25th August 1782 Mary was walking along what we know as the ancient highway from Deal to Sandwich carrying a bundle. She had just passed the Chequers Inn when she passed a man sitting by the side of the road. 

He stopped Mary and asked the way to Sheerness, which is a long way from Sandwich, then he asked her for money. 

Mary refused, the man who was a foreigner then attacked Mary, ultimately killing her and dumped her body in a ditch. 

He then made off in the direction of Sandwich carrying the bundle Mary had been carrying. 

The man did not know that he had been seen by the 13 year old son of a Looker, ( a Looker was a Sheperd) the boy was scared that he would share the same fate as Mary so he hid until the man was out of sight, then he set off in the direction of Deal and raised the alarm. 

It was found that the man Martin Lash (Laas) was a deserter from a ship anchored in the Downs, he was Norwegian and aged 27. 

He was finally found asleep with Marys bundle next to him, in a churchyard in Folkestone which is nearly 20 miles away from Sandwich. 

He was taken to Maidstone Gaol, tried and executed for the crime.

The stone still stands in remembrance of Mary Bax. 

I am glad that I chanced upon the stone.

I don’t think Mary was buried at this spot, as I found this entry:

"Mary Bax was buried at St Peter's Church Sandwich, her gravestone was cleared away in the last century to tidy the graveyard but is still recorded in the parish records."

Lens Dilemma

Well I have'nt written on my blog for a few months and decided it was time to get it up to date, it's been an eventful time none the less.
Try as I might I just was'nt happy with my Sigma 150-600mm Sport, some results were excellent while others were shall we say lack lustre to say the least !

So I decided to take the plunge and sell it, it is no more !

Whilst on the subject of selling obviously we all want to get as much money as possible for our kit, selling on Ebay is going to cost you 14% of your sale price, to avoid this I posted my lens on Gumtree, I had three replies all of which were scam merchants, they say yeah want it and ask you to send payment details for your PayPal account and then they send you a dodgy email that looks like it has come from PayPal, saying that a payment has been received and will be held until a tracking number has been entered at which time the funds will be released into your account, yeah right ! 
The scammer then follows this email up with a " I have paid you can you dispatch today" they even say they will pay extra if you can get the item on next day delivery.

Don't fall for these scammers be careful with your stuff !!!

Next I have to decide what to replace it with, of course I would like to go out and buy a Canon 500mm f4 l is mk2 but even 2nd hand these beauties are over £6k so that is not going to happen, I just cannot warrant spending that sort of money on a lens, if I was earning a living from my photos it would be a different story.

Canon 7dmk2 Canon 100-400mm mk2 @ 400mm 1/640th f7.1 iso125

So the hunt is on, Sigma have a 500mm f4 in their armoury it has very good reviews, is the same weight as the Canon 500mm mk2 and according to a lot of the reviews I have read has a very similar image quality to the Canon version.

Currently the price for a new Sigma 500mm f4 is £4999 or very close to it everywhere I have looked I have seen it for £3999 on Amazon sold by a third party seller, I have emailed the seller but never had a response ! so that looks like a non starter.

Canon 7dmk2 Canon 100-400mm mk2 @ 400mm 1/640th f7.1 iso160

Other options are another Canon 500mm mk1 these can be had for around £2800 to £3800, mint condition being at the £3800 end of the scale.

I am tempted as the Canon 500mm f4 l is mk1 is a great lens, its also possible to pick up a Canon 600mm f4 l is for similar money, but is that going to be too heavy for my old bones ! and there is the repair issue should something go wrong with the lens, mk1's are getting a bit long in the tooth and are no longer supported by Canon.

As soon as I have made my choice I will put a new post up about it.

Sigma 150-600 Sport Further Update On Auto Focus Micro Adjustment

After the loss of the settings from the AFMA table, I was miffed to say the least and decided to do a bit more work and report on the method and accuracy of the results.

As mentioned previously the Sigma 150-600mm Sport has the ability to be MA'd at 16 different points across the focal range using the Sigma Dock.
Unfortunately there is a lot of guess work involved, by this I mean you have to

1. take a shot of your target, 
2. review it, 
3. remove the camera body from the lens,
4. put the dock on make an adjustment, 
5. remove the dock, 
6. put the body back on
7. repeat the process

This has to be repeated for all 16 points multiple times for each point, which is daunting and time consuming.

So I thought I would try and come up with a similar method or at least a more streamlined method.
The first thing I did was get a DOF calculator out, using the widest aperture and the following distances 2.6m,6m,15m and infinity @ 600mm gives the DOF as .55cm,3.34cm,22.9cm and 93.4cm
which is ok but you need a target with a front to back length of at least a metre if not more.

Repeat these DOF calcs @ 400mm and you get 1.36cm, 8cm, 52.2cm and 211.7cm
Repeat these DOF calcs @ 250mm and you get 3.72cm, 21cm, 135.1cm and 548.5cm
Repeat these DOF calcs @ 1500mm and you get 10.5cm, 59.6cm, 383.2cm and 1619.7cm
The infinity calcs were done at 30m which is questionable, and to be honest I never bothered attempt any infinity adjustments.

How the hell do can you see how accurate your focal point is when you have such a huge DOF ?
the smaller distances are fine you can easily see the edges of the DOF as the sharp edges become less defined.
As for attempting to MA 150mm @ infinity/30m I'm jiggered if I have a scale that is 16.197m long in me back pocket !

At this stage I kind of lost the will to live.

I  did MA the lens at all focal lengths up to 15m took a long time, I used Reikan Focal Pro, first off I used Canon's built in MA adjustment to see if the Sigma needed tweaking.
At 2.6m no adjustment required  across the focal range Reikan reported 0 was the correct setting
At 6m no adjustment required @ 150mm and 250mm, @ 400mm and 600mm it needed tweaking final setting of -5 and -3 respectively.
At 15m 150mm needed +1, 250mm 0, 400mm 0, 600mm +5

In my humble opinion whilst it sounds like a light bulb moment having all these focal points to MA at in reality and practically it is too much of a faff to use the Sigma Dock, whilst initially I had loads of enthusiasm for this facility it has gone down hill fast.

I will probably end up using the inbuilt Canon MA and just MA it at 150mm and 600mm and be done with it !
Life is too short to be spending any more time on it.

Strange But True

Recently the results I have been getting with my Sigma 150-600 have been somewhat dismal, so today I connected it too the Sigma USB Dock and checked the AF settings only to discover that the entire AF table was empty !!

Note to self: next time write the bloody settings down !!!!

What has happened to em I dont know but that will hopefully explain the soft focus results I have been seeing of late.

Now all I have to do is go through the long drawn out process of setting it back up grrr !
