I don't appreciate receiving Nigerian SPAM emails as private messages here. Which leads me to believe that like SO many of these kinds of forums, they are merely harvesting data for marketing reasons.
Do they really harvest data for marketing reasons?

I have never received spam email from Nigerian sources, at least not recently and definitely not through this forum.

RichA, you have made quite an impact with your entrance mate, and quick at the trigger.

You are prone to such nigerian spams from a variety of sources, unless of course you dont give your email to anyone or type your email anywhere at all

Stefan,
Danny (Unlocker) has put it spot on. I really couldn't see any sense if having the DA*200 for that extra stop. You would be amazed at the quality of DA*60-250 when you use it. And dont forget quite a few of us have the DA*300 which we all know how great it is so for us to be talking about the stunning quality of the DA*60-250 you have to consider it that its based also on the relative quality of the DA*300.

Danny is right when he says if you buy the DA*60-250 while it is still at this price and then later on sell your DA*50-135 you would be in a winner situation. I have never handled the DA*50-135 although I have read some great stuff and seen it also from it, but I think the DA*60-250 is also very very good.

If you were close by I would let you borrow the DA*60-250 and then you could make your own conclusions.

Well, you could also invest in the DA*60-250 and then check it and if you do not like it you could always sell it off. Buy it at the cheaper price and then you can always sell it and I dont think you would lose any money as prices are due to go up any moment now. I bought it and within days the prices jumped so much, glad Mike-P gave me the thumbs up soon he bought his and put it through some tests and knowing the amount of lenses he has had his hands on I knew I couldn't go wrong following his advice.

Mike, if you are reading this get Chris to process your commission on your next purchase

Nice shots Stefan
I like the second one best, that blue tone is really captivating
Well done

HI, thanks for the comments, just wanted to come and add that I have managed to work around it, thanks for your comments and help.

I have learned through experience that you can't generalise trends or attitudes based on region or culture, let alone nationality. In today's age when we live in such a multicultural society and where people can mix up and blend in ways far intense that one can even dare to describe you would be treading thin ice and could end up totally lost.

I purposely steered away from responding to the comment although rhetoric that Nathan put when he touched the subject about where I was from and that back where he is from they do things differently. This is the sort of questions that I would rather not respond because a simple answer which in fact is "I am British" which in fact I am would raise still more questions. I have been there and I know the avalanche of questions that come flooding such as "but were you born here?" or, "are you originally from here" or for example "oh but which is your mother tongue if not english" aaahhh the stuff I am asked is just ridiculous. This is my home and my signature shows that I am in London, that should suffice and I can't see any real reason for a point to be raised in a comment regarding where would I come from.

Oh by the way, this is just a friendly comment, no issues raised and I will make sure to add a smilie in the end

I wonder if someone could help me understand a couple of things with regard to a circuit that I am trying to assemble. Now I know this is supposed to be a very simple basic circuit but please bear in mind I am taking my first steps and have done a tiny progress in as much as managing to assemble the kit up to a certain point. There are couple of things that now I really would appreciate some help in.

1- the Thyristor or (SCR as mentioned in this diagram Comment Image
I am assuming I have connected the Anode, Gate and Cathode correctly. I get the flactuation in voltage when I shine white light on the PT. I am connecting the Gate which I am assuming is the middle pole to the resistor and then I am lost with regard to the Anode and Cathode. I see one of them to earth and also connected to the other one, so would that be the Anode?

With regard to the 2N2222 transistor I have managed to get it to work by finally finding out the correct way of fitting it, I am hoping, and now when I test the circuit with different PT of varied sensitivity I detect fluctuations in the voltage. I have managed to attach the meter on the Gate and Cathode of the SCR (which I am assuming again is the correct way and these is from where the leads should go to my flash cable that I have stripped). When I shine a white light the voltage goes down to almost 1.2V and when I cut it off it does go to between 5 and 8.8V depending on which PT I attach.

So I am assuming that I have managed to get there but now the problem is the flash doesn't fire when I attach the cables to the SCR. Am I missing something here? Is it because the PT is not getting enough light to bring it down to 0 totally and then cutting it out the flash is not getting the proper surge of voltage to fire it up? A bit lost here, so if someone could give me some hints or tips on what could be wrong here I could try again. The circuit does look straight forward and with the exception of the SCR and the N2222 transistor which gave me a bit of a headache to figure it out how to finally fit it I think I have the correct assembly.

I am off to Maplin again to see if I can get a laser light, am hoping that lack of concentrated beam of light might be affecting also so I want to get that one correct too, just in case its affecting.

One last thing, When I hold the stripped wire from the flashgun and touch the two poles of the SCR the flash does fire, its only when I have linked it and then play with the light shining on the PT that the flash doesn't fire at all. Is there something that I might be missing here too?

Thanks for all your help.
The diagram I am following is on this page under Photogate Trigger.

I just wanted to add a quick word on John's defence on the issue of one comment essentially that he removed from this thread in particular. He has also justified that leaving my comment made no sense as it was in response to the comment that needed to be deleted.

And as Martin also has mentioned it was really a comment that would have flared up emotions here to the extent that the issue of closure of the other thread would have even seemed tiny in comparision.

I fully support him in removing that. That was an excellent judgement call and I can assure you that if that had been left there this thread would definitely have turned pretty nasty. My comment was particularly in response to that one trying to soothe the tone of the previous comment and asking the OP to take it a bit easy. I remember even adding that this thread was on the verge of being closed.

Thankfully John immediately noticed it and removed it before it exploded into a nasty argument.

We certainly wouldn't have been having the continuing discussion more amicably in my opinion on this thread and it would have been rightly closed in my view.

Ooops, what happened to my comment and Bob's one that was in the thread just a few minutes ago? Been fumigated from the thread I think. I am lost here, I am sure I did click "Add Comment" at the end of it and now I don't see it here anymore.

Does this mean it wasn't suitable for the forum?

Totally lost now
Look's like they have been removed..Amin.
I am sure there wasn't anything offensive in those comments, unless I am missing something here.

Chris, this is still a friendly forum, we are just having a difference of opinion, that's all, but discussing it in a very civilised manner.
